An aortic dissection is one of the most time-sensitive medical emergencies encountered in medicine. Although relatively uncommon, it carries a high risk of death if not recognized and treated quickly. In this episode of Health in Harlem on WHCR 90.3 FM, Dr. Maurice Selby and the team discuss what an aortic dissection is, why it occurs, and how early recognition can save lives.
The program explains the anatomy and function of the aorta, common risk factors—including high blood pressure, connective tissue disorders, and smoking—and the warning signs that should never be ignored. Listeners will learn how an aortic dissection differs from a heart attack, why rapid diagnosis is essential, and how emergency physicians and cardiovascular surgeons work together to provide life-saving treatment. The episode also highlights the importance of controlling blood pressure and other cardiovascular risk factors to reduce the likelihood of this devastating condition.
As always, Health in Harlem is committed to improving health literacy by providing reliable, evidence-based medical information that helps listeners make informed decisions about their health and know when to seek emergency care.

Hello, folks. Dr. Maurice Selby here, medical director, producer,
00:00:08.087 --> 00:00:14.848
and co-host of Health in Harlem on WHCR 90.3 FM and the Health in Harlem podcast.
00:00:15.614 --> 00:00:19.887
While we strive to bring you the most up-to-date, reliable, evidence-based information
00:00:19.887 --> 00:00:24.227
to help you live the healthiest life possible, this show does not substitute
00:00:24.227 --> 00:00:28.467
for an evaluation by a trained and licensed medical professional.
00:00:29.332 --> 00:00:34.161
It is highly recommended that any advice or recommendations on medications,
00:00:34.446 --> 00:00:38.747
treatments, nutrition, fitness, preventive services, etc.
00:00:39.682 --> 00:00:44.401
Be implemented under the guidance and supervision of your primary medical provider
00:00:44.784 --> 00:00:46.311
or appropriate specialist.
00:00:46.938 --> 00:00:51.647
With that said, we hope that you enjoy and learn from our program and please
00:00:51.647 --> 00:00:55.646
be sure to let us know how we can best serve you in future shows.
00:01:22.004 --> 00:01:25.424
Ladies and gentlemen of the listening audience. My name is Maurice Selby,
00:01:25.744 --> 00:01:28.223
a.k.a. Dr. Mosel. My name is Reed.
00:01:28.995 --> 00:01:37.493
And you're listening to Health in Harlem on WHCR 90.3 FM New York and the Health in Harlem podcast.
00:01:37.969 --> 00:01:42.699
And ladies and gentlemen, we have a really special program.
00:01:43.308 --> 00:01:46.704
I think anytime you give us an opportunity, Reed and I were discussing this,
00:01:47.011 --> 00:01:50.694
anytime we get an opportunity to talk about heart disease in this country,
00:01:50.694 --> 00:01:54.954
cardiovascular disease, We're going to take it. All right. That's it. We're going to take it.
00:01:55.700 --> 00:02:03.054
Unfortunately, on Saturday, July 11th, 2026, Senator Lindsey Graham was reported
00:02:03.054 --> 00:02:05.887
to be deceased by media outlets.
00:02:06.305 --> 00:02:11.854
First and foremost, while I, me personally, and just as a disclaimer,
00:02:11.854 --> 00:02:16.179
this is not the opinion of Health in Harlem as a whole,
00:02:16.737 --> 00:02:19.654
but I personally did not agree with its politics, but I think it's important
00:02:19.654 --> 00:02:24.594
that we observe a moment of silence for Senator Graham before we proceed.
00:02:25.806 --> 00:02:30.000
Now, as tragic as Senator Graham's passing was, I'm hoping that we can have
00:02:30.000 --> 00:02:32.230
conversations about his,
00:02:33.296 --> 00:02:37.417
passing and that this might spawn more robust conversations in this country,
00:02:38.038 --> 00:02:40.810
that allow for a healthier, a healthier political climate.
00:02:40.810 --> 00:02:45.340
And really just in terms of our democracy, right, healthier conversations as
00:02:45.340 --> 00:02:50.057
a whole that can contribute to that as far as our political climate,
00:02:50.434 --> 00:02:54.960
having good faith debates and or you can even call them arguments.
00:02:54.960 --> 00:02:57.800
Right. But in good faith in that ultimately through compromise,
00:02:57.800 --> 00:03:03.586
we're able to ensure that Americans have what they need to live lives that are happy and productive.
00:03:03.962 --> 00:03:07.670
And on this program, of course, we talk about that from the standpoint of health.
00:03:07.670 --> 00:03:13.499
Primarily, there is still not a lot of information about what happened with Senator Graham.
00:03:13.714 --> 00:03:17.000
But some things that seem to be clear at this point was that it was reported
00:03:17.000 --> 00:03:21.507
that there was a call for emergency assistance to assistance to Senator Graham's residents.
00:03:22.041 --> 00:03:26.110
It was reported that there was a complaint of chest pain, and Senator Graham
00:03:26.110 --> 00:03:28.526
was taken to a local hospital where he ultimately...
00:03:29.382 --> 00:03:34.221
Was declared deceased. Preliminary reports from the medical examiner determined
00:03:34.221 --> 00:03:38.044
the cause of death to be due to an aortic dissection.
00:03:38.763 --> 00:03:43.829
And again, very tragic as far as the loss of Senator Graham.
00:03:44.636 --> 00:03:46.528
Politics and all of that stuff aside.
00:03:47.096 --> 00:03:53.417
But again, anytime on this program, anytime we have an opportunity to talk about
00:03:53.679 --> 00:03:58.671
things like cardiovascular disease, heart disease, the leading killer of Americans,
00:03:59.240 --> 00:04:00.848
right? We're going to take that opportunity.
00:04:01.335 --> 00:04:05.881
And I'm pretty sure Senator Graham would have been in agreement with that,
00:04:05.881 --> 00:04:07.741
us talking about this topic.
00:04:07.741 --> 00:04:11.531
Yeah, absolutely. And I just want to add the reason why we talk about this so
00:04:11.531 --> 00:04:15.871
much is not only is it the number one killer, and it's such an important topic,
00:04:15.871 --> 00:04:17.644
but largely preventable.
00:04:17.946 --> 00:04:21.651
If this were something that weren't preventable or something like that,
00:04:21.651 --> 00:04:23.433
we probably wouldn't harp on it that much.
00:04:23.908 --> 00:04:28.755
But this is something that with the right information the right treatment plans,
00:04:29.208 --> 00:04:33.731
talking about it can be one of the main causes of prevention just getting that
00:04:33.731 --> 00:04:36.505
information out there sharing it with everybody that you know,
00:04:37.092 --> 00:04:40.643
yeah it's crazy how something like this can be,
00:04:41.267 --> 00:04:46.921
with proper prevention and treatment can be almost eradicated and so it's crazy
00:04:46.921 --> 00:04:50.486
how it continues to persist so widespread,
00:04:51.043 --> 00:04:54.431
and that's why we're so passionate about it because we could save or,
00:04:54.891 --> 00:05:00.301
not we but there could be so many lives saved just with better access to information
00:05:00.301 --> 00:05:04.931
better access to health care prevention literature all that kind of stuff so
00:05:05.251 --> 00:05:08.485
that's why we feel so passionate about it on this show and just
00:05:08.844 --> 00:05:11.219
across the board in this country in the medical industry.
00:05:12.048 --> 00:05:14.601
Facts, man. And that's the thing, Reid. I'm glad you said it,
00:05:14.601 --> 00:05:18.688
put it in those terms, just because it seems like something like this just happens, right?
00:05:18.967 --> 00:05:24.701
Like Senator Graham coming from Ukraine, and there was no indication prior that
00:05:24.701 --> 00:05:28.876
something was amiss, right? And it seemed like this thing just happened.
00:05:29.468 --> 00:05:36.666
And while in the acute sense, yes, a person just develops an aortic dissection acutely often, right?
00:05:37.084 --> 00:05:40.831
The vast majority of cases, this is something that does not just happen,
00:05:40.831 --> 00:05:44.811
right? This is something that develops over a long period of time.
00:05:45.159 --> 00:05:47.342
And we're going to talk about some of the things that lead to that.
00:05:48.251 --> 00:05:52.221
And really from the standpoint of, hey, this is something that for the vast
00:05:52.221 --> 00:05:54.047
majority of people is preventable.
00:05:54.627 --> 00:06:00.101
And that's something that I'm hoping, as difficult as it is to talk about the
00:06:00.101 --> 00:06:05.231
passing of someone, as difficult as it is to just talk.
00:06:06.172 --> 00:06:10.431
About what it takes to live a happy, healthy life in this day and age,
00:06:10.771 --> 00:06:12.611
in this country, there are opportunities here.
00:06:12.611 --> 00:06:16.035
And I'm hoping that we can leave this conversation empowered as we get into that.
00:06:16.360 --> 00:06:21.387
Just a couple of things that we definitely need to before we delve into our main topic.
00:06:21.747 --> 00:06:27.767
We need to talk about this cyclospora outbreak, a lot of updates as far as.
00:06:28.582 --> 00:06:34.867
Taylor Farms de Mexico on July 17th announced that they were they were voluntarily
00:06:34.867 --> 00:06:40.303
removing all of iceberg lettuce sourced from central Mexico from the U.S. market.
00:06:40.831 --> 00:06:47.919
So they initiated a recall that included market side brand products available at Walmart.
00:06:48.395 --> 00:06:50.947
Also, there was a good amount of
00:06:50.947 --> 00:06:54.860
this stuff sent to Taco Bells throughout multiple states in the country.
00:06:55.435 --> 00:07:00.077
And so we've seen these recalls. We've seen Taco Bell even sort of put out notices
00:07:00.077 --> 00:07:04.565
that they were removing iceberg lettuce from their menus in affected states.
00:07:05.198 --> 00:07:09.507
And and so, right, we see this thing going around is cyclospora infection.
00:07:09.507 --> 00:07:12.157
And this is what we were talking about last week on the program.
00:07:12.157 --> 00:07:15.997
Ladies and gentlemen, it's just paying attention to these bulletins as far as
00:07:15.997 --> 00:07:23.181
these recalls, as far as restaurants and restaurant chains that have been affected in order to avoid this.
00:07:23.588 --> 00:07:26.327
And again, I mean, from the standpoint, right, the bright side,
00:07:26.327 --> 00:07:35.077
we were talking about, yeah, this is not COVID or an equally morbid or mortal disease, right?
00:07:35.077 --> 00:07:39.238
Something that is causing widespread death. This is not it. But we talk about just.
00:07:40.058 --> 00:07:46.564
Inconvenience, to put it lightly, right? You know, really bad diarrhea and other
00:07:46.564 --> 00:07:50.954
GI upset, gastrointestinal upset. This could be avoided by avoiding this infection.
00:07:50.954 --> 00:07:53.938
So really pay attention to these advisories.
00:07:54.489 --> 00:07:55.993
Taylor Fresh Foods, right?
00:07:56.560 --> 00:08:03.317
Distributed these recalled iceberg products from June 29th through July 16th.
00:08:03.840 --> 00:08:08.254
There are a number of states. We'll actually put the link to the CDC advisory
00:08:08.254 --> 00:08:12.716
on this. So you can look at the affected states, but it is a wide range of them.
00:08:12.913 --> 00:08:16.884
I think they predominantly sort of narrowed it down to five states that are
00:08:16.884 --> 00:08:21.584
most severely affected, but I'm looking at a list of at least 20 here in which
00:08:21.584 --> 00:08:23.315
we need to be on the lookout for.
00:08:24.264 --> 00:08:29.644
And again, this is still something that is emerging as far as this information.
00:08:29.644 --> 00:08:33.039
And so we might see these recalls extended right to other states,
00:08:33.550 --> 00:08:36.934
other products, and as we said, even other restaurants involved.
00:08:36.934 --> 00:08:39.767
So just be on the lookout for that information.
00:08:40.272 --> 00:08:45.384
Yeah. And from what I understand even about the CDC test for cyclospora in the
00:08:45.384 --> 00:08:51.156
Taylor Farms products was that the initial positive tests turned out to be a false positive.
00:08:51.574 --> 00:08:57.005
So like you said, it was all voluntary recalls by Taylor Farms to take their products off the shelf.
00:08:57.400 --> 00:09:02.374
But as of right now, the CDC still has not had a confirmed positive test for
00:09:02.374 --> 00:09:06.711
cyclospora in any of their samples so continues to be out there,
00:09:07.303 --> 00:09:13.549
could be one huge batch of contaminated produce it could be a couple different things.
00:09:14.165 --> 00:09:18.704
So I think just like we said in the last show, paying attention to where your
00:09:18.704 --> 00:09:22.367
produce comes from, maybe buying local produce could be a bit safer.
00:09:22.895 --> 00:09:27.854
Cooking your food, cooking your greens, switching to maybe cutting out the salad
00:09:27.854 --> 00:09:33.074
and going for something, baked cauliflower or something that might be a little bit low risk.
00:09:33.074 --> 00:09:38.454
I think part of the difficulty with cyclospora is because of the long incubation
00:09:38.454 --> 00:09:42.205
period, it's really difficult to tie down to a specific thing.
00:09:42.524 --> 00:09:45.964
Whereas if you get food poisoning or something it's like oh okay yeah i had
00:09:45.964 --> 00:09:49.914
that sketchy nachos from 7-eleven last night that probably did it,
00:09:50.494 --> 00:09:55.794
whereas you have to think back up what did i have 10 days ago within that incubation
00:09:55.794 --> 00:10:01.128
time frame and another point of complication without getting too into politics
00:10:01.546 --> 00:10:06.514
but the cdc had a cyclospora lab they still do but it did receive very significant
00:10:06.514 --> 00:10:10.851
cuts with the doge cuts the department of government efficiency,
00:10:11.600 --> 00:10:15.734
that was led by elon musk this is probably another thing that's hampering their
00:10:15.734 --> 00:10:19.854
abilities to get out there and test as many samples as possible it's just their
00:10:19.854 --> 00:10:22.351
reduced capacities for these kinds of things.
00:10:24.252 --> 00:10:30.944
Yeah man another thing that's going on probably as we are recording this they
00:10:30.944 --> 00:10:35.663
are getting started on this There is a,
00:10:36.317 --> 00:10:44.008
convening of the FDA Advisory Committee Thursday, July 23rd and July 24th.
00:10:44.118 --> 00:10:47.774
This will be a meeting mainly to determine whether specialized pharmacies can
00:10:47.774 --> 00:10:53.084
produce injectable peptides, several injectable peptides that were banned by
00:10:53.084 --> 00:10:55.785
the Food and Drug Administration several years ago.
00:10:56.406 --> 00:10:59.874
This is a 19-member committee of largely pharmacists, physicians,
00:10:59.874 --> 00:11:04.818
and scientists that I will meet over the course of the next couple of days. And.
00:11:05.462 --> 00:11:09.638
There is concern that some of the experts on this panel or some of the individuals
00:11:09.638 --> 00:11:13.970
on this panel are members of the committee that sell or dispense peptides,
00:11:14.237 --> 00:11:17.948
thus presenting a potential serious conflicts of interest with respect to the
00:11:17.948 --> 00:11:20.147
issues to be discussed at this meeting.
00:11:20.692 --> 00:11:24.108
This is just one of those things that really we're talking about this on Health
00:11:24.108 --> 00:11:27.939
in Harlem from the standpoint, ladies and gentlemen, of peptides, right?
00:11:28.253 --> 00:11:34.162
On many corners of the Internet and especially on social media are all the rage.
00:11:34.592 --> 00:11:37.438
You see a lot of influencers sort of talking about this stuff,
00:11:37.438 --> 00:11:42.048
the stacks, quote unquote, that they do or the regimens that they sort of abide
00:11:42.048 --> 00:11:48.006
by with various peptides to achieve certain outcomes, wellness outcomes.
00:11:48.634 --> 00:11:53.048
Just be mindful that now it's not right to sit here and say that,
00:11:53.048 --> 00:11:57.558
oh, man, peptides are just, you know, evil and, you know, totally disregard
00:11:57.558 --> 00:11:59.891
this stuff. That's not what we're saying on Health and Harlem.
00:12:00.262 --> 00:12:05.628
There are peptides that are in regular use, that are part of regular pharmacologic
00:12:05.628 --> 00:12:10.788
therapies, things like insulin, even GLP-1 medications, right,
00:12:10.788 --> 00:12:13.474
such as terzepazide, ozempic,
00:12:13.916 --> 00:12:15.971
you know, those things. Those are peptides.
00:12:16.546 --> 00:12:21.028
The difference is that these are peptides that have been studied through randomized
00:12:21.028 --> 00:12:25.038
controlled trials, looked at for not only their primarily safety,
00:12:25.378 --> 00:12:28.828
first and foremost, but their efficacy, right, that they actually work and achieve
00:12:28.828 --> 00:12:31.448
the health outcomes that they were designed to achieve.
00:12:32.336 --> 00:12:37.451
Sort of lead to, right? So blood sugar control, especially with diabetes or
00:12:37.451 --> 00:12:44.055
even with the recent use of GOP-1s, right, for dealing with challenges in obesity and overweight.
00:12:44.981 --> 00:12:49.761
That's what those were, right, studied for. These peptides, these other things
00:12:49.761 --> 00:12:53.824
that are out there, we need to be careful because there's just not sufficient evidence.
00:12:54.242 --> 00:12:58.031
And I think that'll be sort of what will be hashed out today or over the next
00:12:58.031 --> 00:13:01.509
couple of days with this committee, right, is what is the evidence showing us?
00:13:01.945 --> 00:13:05.161
Are they, number one, first and foremost, safe, right?
00:13:05.161 --> 00:13:09.221
And especially we're talking about doling these out to compounding pharmacies
00:13:09.221 --> 00:13:12.041
that'll sort of be producing this stuff, right?
00:13:12.041 --> 00:13:15.131
What is the safety around them? What is the evidence as far as efficacy,
00:13:15.131 --> 00:13:21.885
right? As far as how they work and are they effective at achieving the goals, right?
00:13:22.445 --> 00:13:24.851
That they're designed for. That's the, those are the questions.
00:13:24.851 --> 00:13:26.381
That's what's going to be up for debate.
00:13:26.886 --> 00:13:30.259
And it's just something to be on the lookout for.
00:13:30.758 --> 00:13:35.239
We'll be definitely, we talked about already, like we need to devote time to this
00:13:35.646 --> 00:13:39.391
on Health in Harlem so that folks, regardless of what happens over the next
00:13:39.391 --> 00:13:44.461
couple of days with this advisory committee meeting, right, we can inform you
00:13:44.461 --> 00:13:46.174
all, give you information that you can make,
00:13:46.766 --> 00:13:48.577
really informed decisions about this.
00:13:49.030 --> 00:13:53.071
But it's something that I would say in general, I would be very careful with
00:13:53.071 --> 00:13:56.681
using any of these substances right now with the limited evidence that is out
00:13:56.681 --> 00:14:00.741
there as far as their safety and even regarding their efficacy or.
00:14:01.381 --> 00:14:06.451
You know their ability to achieve the outcomes that are desired and we've seen
00:14:06.451 --> 00:14:08.860
it all right read read as far as weight loss and,
00:14:09.394 --> 00:14:15.001
individuals using them for like muscle you know yeah anti-aging and anti-aging
00:14:15.321 --> 00:14:17.225
everything there's no evidence for a lot of these things.
00:14:18.534 --> 00:14:20.870
That people are promoting them for, sleep and all that stuff,
00:14:20.870 --> 00:14:22.874
like just be wary of that.
00:14:23.106 --> 00:14:26.433
And they come with costs too. So even outside of just safety,
00:14:26.960 --> 00:14:30.980
right, first and foremost, and do they actually work, but people doling out
00:14:30.980 --> 00:14:34.920
a lot of funds, a lot of money that can be put to other things that could achieve
00:14:34.920 --> 00:14:35.946
better health outcomes,
00:14:36.596 --> 00:14:39.990
right, and that have better evidence behind them, such as getting some good,
00:14:40.450 --> 00:14:42.741
running or walking shoes, right?
00:14:43.008 --> 00:14:45.980
If you're going to do a lot, a couple hundred dollars, maybe it's for an investment
00:14:45.980 --> 00:14:51.500
in a nice pair of shoes you can go out and get physical activity that'll help you with a lot of things,
00:14:52.132 --> 00:14:56.500
yeah just an example absolutely and i just want to echo what you said with currently
00:14:56.500 --> 00:15:00.582
there's no fda approved peptides i believe right.
00:15:01.444 --> 00:15:04.927
Well, I mean, aside from what we mentioned as far as like things like insulin,
00:15:05.217 --> 00:15:08.503
Ozempic or, you know, the GOP ones, those are peptides.
00:15:08.694 --> 00:15:12.334
So that's the thing that I think was misconstrued because some of the really
00:15:12.334 --> 00:15:17.715
vocal proponents of this are like, well, you know, this is this is revolutionary and we need to.
00:15:18.000 --> 00:15:21.680
It's like, no, nobody ever said that these things don't deserve to be studied.
00:15:22.133 --> 00:15:26.910
Right. Or investigated further. What we said is that right now is not sufficient evidence.
00:15:27.299 --> 00:15:31.874
Oh, I think what I was thinking is there's no currently FDA-approved compound
00:15:31.874 --> 00:15:34.637
peptides, right? They don't approve anything compounded.
00:15:34.984 --> 00:15:40.794
So a lot of the stuff that you're seeing for sale on websites like HIMSS or
00:15:40.794 --> 00:15:44.204
those sort of direct-to-consumer things where you just kind of fill out a survey
00:15:44.204 --> 00:15:47.770
and you get a prescription for a compounded peptide thing.
00:15:48.182 --> 00:15:53.424
None of that is FDA-approved. And while it may turn out in the future to be,
00:15:53.944 --> 00:15:56.750
useful with limited side effects, none of that is really studied.
00:15:57.127 --> 00:16:02.404
And so, again, it's just like a risk sort of benefit scenario.
00:16:02.787 --> 00:16:07.404
Whereas it really worth taking a drug that is largely untested,
00:16:07.404 --> 00:16:14.264
side effects unknown, long-term use unknown, for aesthetic reasons or whatever it might be.
00:16:14.699 --> 00:16:19.574
That's up for you to decide but I definitely lean more on the safety side of
00:16:19.574 --> 00:16:22.843
things so that's just where I stand with those kinds of things.
00:16:23.778 --> 00:16:28.448
No, I hear you, man. Be careful. That's what we're saying. And I'm really going
00:16:28.448 --> 00:16:32.078
to be looking at this and seeing what develops or what comes out of this committee
00:16:32.078 --> 00:16:33.778
meeting over the next couple of days.
00:16:33.778 --> 00:16:36.958
And we'll bring that to you on this program so you can make,
00:16:36.958 --> 00:16:38.990
again, more informed decision.
00:16:39.228 --> 00:16:43.038
I would not be surprised, honestly, if they came out of this.
00:16:43.038 --> 00:16:47.042
Now, one thing to understand is that this is not binding as far as what this committee says.
00:16:47.367 --> 00:16:49.368
Right. That does not mean that
00:16:49.368 --> 00:16:55.613
the FDA commissioner or the agency is obligated to follow that advice.
00:16:56.107 --> 00:17:01.108
Right. And it can even be overruled by the secretary of the Department of Health
00:17:01.108 --> 00:17:05.127
and Human Services, RFK, who is a proponent of these things.
00:17:05.331 --> 00:17:09.644
But just be wary of, again, right, making an informed decision,
00:17:09.998 --> 00:17:13.318
because unfortunately, and this is kind of what we alluded to,
00:17:13.318 --> 00:17:15.547
right, six members of this committee,
00:17:16.194 --> 00:17:20.808
having some conflicts of interest, even just politically, right?
00:17:20.808 --> 00:17:25.818
There are things that might be informing this committee or informing this decision
00:17:25.818 --> 00:17:31.967
ultimately of the FDA that might not necessarily be have the backing of,
00:17:32.576 --> 00:17:35.850
you know, the large consensus of the scientific community.
00:17:36.274 --> 00:17:39.821
And especially when we talk about the evidence behind them, right, might be lacking.
00:17:40.198 --> 00:17:44.686
So that is that's why we want you to be careful in making decisions about this stuff.
00:17:46.250 --> 00:17:50.081
With that said, whew, that was a lot, man. Oh my goodness. Just those two topics.
00:17:50.308 --> 00:17:52.086
I mean, those are shows in and of itself.
00:17:52.986 --> 00:17:55.758
Let's get to the topic at hand, man. Let's get to the topic at hand.
00:17:55.985 --> 00:17:57.099
We're going to start with a fist.
00:17:57.471 --> 00:18:03.106
Folks, simple enough. I think this sets up a solid analogy. So just hang on to that thought.
00:18:03.946 --> 00:18:07.516
Ball up your fist in front of you right now and just look at it.
00:18:07.516 --> 00:18:09.353
Or if you want to picture it, close your eyes.
00:18:10.086 --> 00:18:13.536
Fist is powerful. That's one thing, at least in my mind that pops,
00:18:13.536 --> 00:18:17.086
you know, if I make a random association, but just picture your mind,
00:18:17.086 --> 00:18:21.468
just the size or even before you of your fist and,
00:18:22.101 --> 00:18:25.396
take into account the size of your fist and understand, right,
00:18:25.396 --> 00:18:27.718
this is about the size of the average heart.
00:18:28.298 --> 00:18:33.196
The average heart weighs about 250 grams or so. So you can even maybe think
00:18:33.196 --> 00:18:37.615
about holding an apple or grapefruit to get an idea as to just the solid weight
00:18:38.028 --> 00:18:40.001
of our heart. And you got it right, right there.
00:18:40.576 --> 00:18:45.076
And now just, we're going to take a second to just talk about the cardiac cycle
00:18:45.076 --> 00:18:47.246
and a little bit of hemodynamics.
00:18:47.803 --> 00:18:53.482
So the heart, right, in and of itself beats about 70 to 80 beats per minute.
00:18:53.922 --> 00:18:58.216
We're talking about well over 100,000 beats per day over the course of one's
00:18:58.216 --> 00:19:02.399
lifetime, 2.5 billion beats over the course of our lives.
00:19:03.188 --> 00:19:07.728
And now let's go back to that fist, right? Because we're talking about pressure, essentially.
00:19:08.204 --> 00:19:12.006
Now, pressure is not a bad thing. It actually facilitates flow.
00:19:12.883 --> 00:19:16.156
And ideally, right, we talk about our hearts pumping, right?
00:19:16.156 --> 00:19:18.946
We need pressure in order to get blood where it needs to be,
00:19:18.946 --> 00:19:23.106
right? To our vital organs, to our periphery, right? Our muscle,
00:19:23.106 --> 00:19:26.506
our musculoskeletal system, so we can go on and do the things that we need to
00:19:26.506 --> 00:19:27.951
do in our day-to-day lives.
00:19:28.590 --> 00:19:31.996
And especially when we talk about nourishing our vital organs,
00:19:31.996 --> 00:19:36.945
so our heart, brain, kidneys, right? Pressure is not a bad thing,
00:19:37.189 --> 00:19:41.653
right? This allows us to carry on our vital functions in our bodies.
00:19:42.448 --> 00:19:46.128
And we think about the aorta, right, the topic of this program,
00:19:46.604 --> 00:19:50.139
it is held under constant tension as it carries blood from the heart.
00:19:50.627 --> 00:19:54.634
And depending on the needs of our body, right, it can even auto-regulate, right?
00:19:55.114 --> 00:19:58.597
It is an elastic vessel, has multiple layers.
00:19:58.708 --> 00:20:04.338
If we imagine a garden hose, right, you have an inner lining or the core layer, right, an inner tube.
00:20:04.901 --> 00:20:08.959
You also have a reinforcement layer, right, which is usually a sort of a mesh
00:20:09.389 --> 00:20:12.326
or polyester line or nylon fibers, right?
00:20:12.912 --> 00:20:16.436
Typically arranged in an array to give support to that.
00:20:16.953 --> 00:20:21.770
And then finally, we have sort of an outer layer that provides protection,
00:20:22.129 --> 00:20:25.711
right, for the hose as a whole, garden hose as a whole.
00:20:26.471 --> 00:20:29.484
But thinking about it, right, the pressure subjected to, you can't just have
00:20:29.484 --> 00:20:33.994
a solid tube or a simple tube because, right, it'd be more prone to rupture.
00:20:33.994 --> 00:20:38.261
It might not be as elastic if it were just like, let's say plastic that it was made out of.
00:20:38.824 --> 00:20:44.343
And so we have this multi-layered hose that allow us to sort of water our garden,
00:20:44.837 --> 00:20:49.076
and carry out other sort of home care things, right?
00:20:49.668 --> 00:20:51.914
But then we think about the layer of our arterial system, right?
00:20:51.914 --> 00:20:55.674
And we're talking about something that is, right, multi-layered, right?
00:20:55.674 --> 00:20:58.354
And there's a purpose for that because it carries out different functions.
00:20:58.354 --> 00:21:03.004
So the layers of our arterial system are very similar in that we have an intimal
00:21:03.004 --> 00:21:08.294
layer composed of cells that are very closely aligned or approximated there, right?
00:21:08.294 --> 00:21:12.274
Think intimate, Right. When we think of the intima, something is very close
00:21:12.274 --> 00:21:17.244
and it even keeps things within it. Right. Such as our blood volume circulating
00:21:17.244 --> 00:21:19.034
throughout the body, even keeps
00:21:19.034 --> 00:21:22.168
things out of it, such as contaminants and stuff from the environment.
00:21:22.901 --> 00:21:27.017
And then we think about the media layer, right? So this is the sort of middle layer.
00:21:27.452 --> 00:21:36.032
It is very much composed of smooth muscle that facilitates blood flow in our circulatory system.
00:21:36.032 --> 00:21:41.062
And so this smooth muscle can contract and lessen the diameter of those blood
00:21:41.062 --> 00:21:45.274
vessels, right? And increase the pressure to distribute blood throughout our bodies.
00:21:45.535 --> 00:21:51.232
They can also relax, right? And also decrease our blood pressure through that.
00:21:51.232 --> 00:21:54.862
But again, to facilitate the movement of blood throughout our bodies to nourish
00:21:54.862 --> 00:21:56.971
our cardiovascular system.
00:21:57.525 --> 00:22:02.349
And then finally, we have the adventitial layer or the tunica adventitia,
00:22:02.599 --> 00:22:05.995
which is mostly a lot of connective tissue.
00:22:06.215 --> 00:22:11.706
There's a lot of collagen and elastin in that layer to allow flexibility of those blood vessels.
00:22:12.125 --> 00:22:16.352
And then also there are blood vessels in that, microscopic blood vessels that
00:22:16.352 --> 00:22:22.522
supply nourishment to the blood vessel itself, in addition to nerves that are in that layer that.
00:22:24.062 --> 00:22:30.282
Allow our bodies to communicate, our brains to communicate to the smooth muscle
00:22:30.282 --> 00:22:35.914
on whether to constrict or to dilate in order to facilitate blood flow throughout the body.
00:22:36.601 --> 00:22:41.252
And we can go on, man. We can have a whole show where we're just talking about,
00:22:41.732 --> 00:22:44.610
hemodynamics and blood flow throughout the body.
00:22:44.954 --> 00:22:50.562
But one of the things to really understand, the organ itself is an incredible organ, right?
00:22:50.956 --> 00:22:57.959
It is the most elastic portion of our circulatory system, the arterial system.
00:22:58.401 --> 00:23:01.232
And that is really because it needs to accommodate the blood flow that's coming
00:23:01.232 --> 00:23:04.632
from the heart, that is being pumped from the heart, right? And direct that
00:23:04.632 --> 00:23:06.580
blood to our vital organs, right?
00:23:06.899 --> 00:23:10.552
Sending it up to our brains to provide nourishment for our neurons so that we
00:23:10.552 --> 00:23:18.172
can think, we can carry out our, you know, automatic functions such as breathing, right?
00:23:18.172 --> 00:23:21.842
But also those things that we do voluntarily, such as, you know,
00:23:21.842 --> 00:23:26.240
moving around, walking around, manipulating our environment in space.
00:23:26.870 --> 00:23:31.712
But then also it has to get that blood to our other organs, right,
00:23:31.712 --> 00:23:36.204
to our gastrointestinal system, shunting that blood down to our extremities
00:23:36.529 --> 00:23:41.620
so that we can move around, really just carrying out all of the vital functions of our body.
00:23:42.857 --> 00:23:45.684
This is what our aorta is designed to do.
00:23:46.281 --> 00:23:50.452
And the fascinating thing is, right, as we said, pressure is not a bad thing,
00:23:50.452 --> 00:23:54.165
folks, right? This is what allows our bodies to redistribute blood,
00:23:54.803 --> 00:23:59.312
but there is a limit to that, right? And that's what we're going to get into.
00:23:59.652 --> 00:24:04.152
Kind of what Reed alluded to earlier is that a lot of the complications that
00:24:04.152 --> 00:24:07.562
we see when we talk about somebody having an aortic dissection,
00:24:07.562 --> 00:24:12.173
we are talking about, right, an endpoint, if you will.
00:24:12.832 --> 00:24:17.726
Right? You didn't just wake up with an aortic dissection one day,
00:24:17.726 --> 00:24:20.251
you know, just randomly somebody develops that.
00:24:20.530 --> 00:24:24.296
In very, very few instances, that's the case. We're talking about something,
00:24:24.296 --> 00:24:29.046
right? A disease that builds up over time that ultimately makes you more prone
00:24:29.197 --> 00:24:31.014
to developing a complication like this.
00:24:31.368 --> 00:24:36.772
And unfortunately, when you reach that stage, right, we're at a point where,
00:24:37.370 --> 00:24:39.786
I'm not going to say very little can be done for you, but we're talking about
00:24:39.786 --> 00:24:44.490
a serious complication that can not only be life-threatening,
00:24:44.989 --> 00:24:47.726
but even if you survive, we're talking about something that could lead to serious,
00:24:48.266 --> 00:24:50.277
disability and something that,
00:24:51.366 --> 00:24:56.516
the vast majority of cases we can entirely avoid by paying attention to some
00:24:56.516 --> 00:25:01.366
of the things that we talk about week in, week out on this show with regards to prevention.
00:25:02.545 --> 00:25:05.766
That's one of the things that we need to get to. Yeah, absolutely.
00:25:05.766 --> 00:25:08.900
And like you said, pressure is not a bad thing. In fact, it's a good thing.
00:25:09.300 --> 00:25:13.406
It's usually the inability to withstand that pressure that causes issues.
00:25:13.406 --> 00:25:17.206
So we'll talk about it in a little bit, but things like hypertension,
00:25:17.206 --> 00:25:23.326
atherosclerosis that affects the ability of the aorta and other components within the,
00:25:23.926 --> 00:25:30.175
circulatory system to expand and contract like it needs to, that's when you run into some issues.
00:25:30.628 --> 00:25:34.566
But let's talk about the topic at hand, aortic dissection. So it's pretty,
00:25:35.226 --> 00:25:38.586
from a comforting level, it's a pretty rare condition, but it's caused by the
00:25:38.586 --> 00:25:39.956
tearing of the aortic wall.
00:25:39.956 --> 00:25:42.714
It's life-threatening and requires immediate medical attention,
00:25:43.190 --> 00:25:48.206
but in terms of rarity, in cases per million people per year,
00:25:48.206 --> 00:25:50.957
it only accounts about 5 to 30 cases.
00:25:51.549 --> 00:25:57.296
For ER visits, specifically ER visits about acute abdominal chest or back pain,
00:25:57.296 --> 00:26:01.493
aortic dissection accounts for about 3 in 1,000 visits.
00:26:01.940 --> 00:26:07.895
So these are people already going to the ER for specifically abdominal chest or back pain.
00:26:08.179 --> 00:26:12.086
A lot of that time, it tends to be cardiovascular. It could be a lot of other
00:26:12.086 --> 00:26:17.554
things, but aortic dissection is only about 3 in 1,000 visits of those kinds of cases.
00:26:18.106 --> 00:26:21.937
Real quick read. I say, thank God. Yeah, I can imagine.
00:26:22.320 --> 00:26:28.596
As an ER doc, man, this is one of those things like you want to get an ER doc's attention. Right.
00:26:29.296 --> 00:26:33.656
This is this is one of those diagnoses to mention or to write.
00:26:33.656 --> 00:26:37.987
Think about it like you. You mentioned this to any emergency room physician,
00:26:38.272 --> 00:26:42.476
you know, physician assistant, nurse practitioner, even nurses that are caring
00:26:42.476 --> 00:26:45.412
for patients that that suffer this complication.
00:26:45.876 --> 00:26:47.322
Right. This diagnosis.
00:26:47.856 --> 00:26:51.686
Right. This is hair raising on all levels. I mean, not only for the patients
00:26:51.686 --> 00:26:55.266
coming through, because we're talking about, you know, at least the way it's
00:26:55.266 --> 00:27:00.238
been described to me by patients, right, is, you know, the worst pain imaginable.
00:27:00.610 --> 00:27:04.439
And just thinking about tearing, you know, tearing discomfort,
00:27:04.915 --> 00:27:08.014
you know, 10 out of 10 pain in severity.
00:27:08.281 --> 00:27:09.768
This is what patients describe.
00:27:10.371 --> 00:27:13.476
Not every patient, because there are some more subtle presentations.
00:27:13.476 --> 00:27:17.906
I always teach our resident physicians and medical students.
00:27:17.906 --> 00:27:22.808
I'm like, you know, this is one of those illnesses that typically present atypically,
00:27:23.359 --> 00:27:25.716
meaning sort of the way it's described in textbooks.
00:27:26.099 --> 00:27:29.516
You know, patients coming in, tearing chest pain as radiating to their back
00:27:29.516 --> 00:27:32.815
or moving to their back. Not everybody comes in like that.
00:27:33.332 --> 00:27:37.726
Right. And they can have variable presentations or variable signs and symptoms.
00:27:38.133 --> 00:27:41.372
But this is something that, you know, is not only scary for patients,
00:27:41.819 --> 00:27:43.506
but the providers caring for these
00:27:43.506 --> 00:27:47.421
patients really because we know how devastating it could be, you know.
00:27:48.182 --> 00:27:54.109
Yeah, absolutely. Like you said, signs and symptoms, typically chest pain, tearing or ripping.
00:27:54.486 --> 00:27:59.212
But it's often severe, not always. Like you said, it can even manifest as kind
00:27:59.212 --> 00:28:04.945
of pain in the back, might even be abdominal pain, neck pain, maybe even a headache.
00:28:05.352 --> 00:28:09.485
So it's not super clear. Sometimes it can masquerade as a heart attack.
00:28:09.839 --> 00:28:14.227
It might not be super clear exactly what it is. But I think.
00:28:14.956 --> 00:28:19.334
With everything taken into account, the signs and symptoms, I think it's also
00:28:19.334 --> 00:28:22.717
important to know who is most at risk for these kinds of things.
00:28:23.100 --> 00:28:27.697
So about 75% of cases occur in those aged 50 to 65 years.
00:28:28.098 --> 00:28:30.345
I think Lindsey Graham was just over 70.
00:28:30.867 --> 00:28:34.153
So a little bit past that age range, but right around there.
00:28:34.513 --> 00:28:37.323
Male gender is the majority of people.
00:28:37.729 --> 00:28:42.504
Those with a history of hypertension atherosclerosis cardiac surgery and connective
00:28:42.504 --> 00:28:47.454
tissue disorders other risk factors include high cholesterol cigarette smoking
00:28:47.774 --> 00:28:52.274
drug use that kind of stuff especially things like cocaine or what we call,
00:28:52.794 --> 00:28:55.254
sympathomimetics yes it can also be,
00:28:55.854 --> 00:29:00.794
the onset of it can be associated with maybe physical exertion leaning down
00:29:00.794 --> 00:29:04.054
to pick up something heavy exercising very heavily,
00:29:04.554 --> 00:29:07.018
weightlifting, that kind of stuff, but not always.
00:29:07.488 --> 00:29:11.848
From what I understand, Lindsey Graham had just gotten home from an overseas trip.
00:29:12.266 --> 00:29:15.794
And so I don't know what he was up to. Maybe he was making his bed,
00:29:15.794 --> 00:29:19.377
moving his mattress around something, but maybe he was just hanging out and sitting down.
00:29:19.806 --> 00:29:22.906
So it's not always associated with physical exertion, but it can be.
00:29:23.522 --> 00:29:28.994
As well as, yeah, just a family history is, I think, one of the most important
00:29:28.994 --> 00:29:31.324
things in these kinds of cases as well.
00:29:31.324 --> 00:29:33.878
And one of the most important things when it comes to prevention,
00:29:34.267 --> 00:29:37.984
knowing your family history of these kinds of things, family history of heart
00:29:37.984 --> 00:29:40.397
attacks, stroke, cardiovascular disease.
00:29:40.774 --> 00:29:45.014
Looking at Lindsey Graham's family history, his parents both died when he was
00:29:45.014 --> 00:29:47.102
20 or when he was in his 20s.
00:29:47.525 --> 00:29:51.934
His mother died of Hodgkin's lymphoma. His father died at age 68,
00:29:51.934 --> 00:29:53.673
I believe, of a heart attack.
00:29:54.033 --> 00:29:57.654
And so this is the kind of thing where if you know your family history and you're
00:29:57.654 --> 00:30:02.854
paying close attention to it, getting checked out from an earlier age and getting
00:30:02.854 --> 00:30:06.974
continual checkups, I think, can play a large role in prevention of these kinds
00:30:06.974 --> 00:30:08.997
of disastrous incidents.
00:30:11.044 --> 00:30:15.218
And especially when we talk about the connective tissue disease component of this reed,
00:30:15.847 --> 00:30:21.367
just because those typically, and we're talking about things such as Marfan's
00:30:21.707 --> 00:30:24.297
syndrome, Ehrlich-Danlos syndrome,
00:30:24.825 --> 00:30:30.467
basically syndromes that are heavily influenced by genetics, right?
00:30:30.467 --> 00:30:36.497
So familial syndromes that can literally change the composition of these blood vessels, right?
00:30:36.497 --> 00:30:40.545
As we said, this multilayered system, the intimal, medial layer,
00:30:40.905 --> 00:30:44.907
and the tunica adventitia could change the composition of those vessels to make
00:30:44.907 --> 00:30:47.888
them more prone to weakening in areas,
00:30:48.266 --> 00:30:51.795
aneurysms developing, and ultimately to things like aortic dissection.
00:30:52.219 --> 00:30:56.747
But we mainly know that through family history. Now, in each of those syndromes,
00:30:56.747 --> 00:31:00.957
there are other things, other characteristics to look out for that can maybe
00:31:00.957 --> 00:31:03.822
hint at somebody having a disorder like that.
00:31:04.170 --> 00:31:09.637
But again, just knowing that family history can be vital, not only for making
00:31:09.637 --> 00:31:13.607
a diagnosis like this, but even right before we even get to the point of diagnosis,
00:31:13.607 --> 00:31:16.087
how do we prevent individuals from having this.
00:31:17.027 --> 00:31:22.816
Complication, even if they do have some some things that make them more predisposed to developing it?
00:31:23.251 --> 00:31:28.876
Right. If you have, let's say, Marfan syndrome, you know, maybe this is something that through,
00:31:29.323 --> 00:31:35.637
surveillance, right, keeping an eye on any aneurysmal or dilated or widened
00:31:35.637 --> 00:31:38.425
segments of the aorta, right, we can reduce,
00:31:38.930 --> 00:31:42.617
the complication of somebody developing an aortic dissection.
00:31:42.930 --> 00:31:46.663
And that's where, as Reed said, right, sort of that regular...
00:31:47.266 --> 00:31:52.512
Care that an individual receives through a primary care physician or a primary
00:31:52.512 --> 00:31:53.726
care provider, whether it's,
00:31:54.208 --> 00:31:58.898
a physician assistant, a nurse practitioner, somebody that you see on a regular basis,
00:31:59.380 --> 00:32:04.202
that makes sure, right, you are staying healthy, that makes sure they are screening
00:32:04.202 --> 00:32:10.160
appropriately for illnesses like this, including the predisposing factors such as hypertension.
00:32:10.992 --> 00:32:15.083
Hypercholesterolemia, those things, right, that is paramount.
00:32:15.245 --> 00:32:16.720
That is of paramount importance.
00:32:17.010 --> 00:32:19.506
And we talk about preventing illnesses like this.
00:32:20.114 --> 00:32:23.835
And I just want to just take a second to talk about, right, the long-term exposure,
00:32:24.341 --> 00:32:29.972
to just high pulsatile pressure and how that can lead to the development of this.
00:32:29.972 --> 00:32:35.324
And we said, right, we're talking, you know, more than 100,000 beats per day of our heart.
00:32:35.672 --> 00:32:41.918
We're talking about over the course of one's lifetime, billions, right, of heartbeats.
00:32:42.295 --> 00:32:48.025
And our arterial system being subjected to that constant pressure over the course of a lifetime.
00:32:48.553 --> 00:32:52.482
So going back to our fist, right? Just thinking about it, I got to create a
00:32:52.482 --> 00:32:58.032
sound effect for this read other than my fist like this, but we can do this
00:32:58.032 --> 00:32:59.063
and just think about, right?
00:32:59.872 --> 00:33:04.712
The walls of our arterial system, the aorta being constantly subjected to that
00:33:04.712 --> 00:33:07.898
pressure over time. And for the most part, right?
00:33:08.327 --> 00:33:10.905
Just again, our...
00:33:11.517 --> 00:33:15.766
Aorta being a very compliant portion of the circulatory system,
00:33:16.079 --> 00:33:22.164
right, with that elastin, the collagen that is embedded in those layers of the
00:33:22.164 --> 00:33:24.824
aorta, right, it can handle that pressure.
00:33:24.824 --> 00:33:28.954
It is designed to accommodate that pressure and redistribute it in order to
00:33:28.954 --> 00:33:31.974
get blood throughout our body, our circulatory system.
00:33:32.438 --> 00:33:35.462
But like we know, right, everything kind of has a limit.
00:33:36.020 --> 00:33:41.418
And eventually from long-term exposure to high pulsatile pressure.
00:33:41.830 --> 00:33:44.144
So meaning, right, we are in the
00:33:44.144 --> 00:33:49.834
realm of high blood pressure that is uncontrolled for a long time, right?
00:33:49.834 --> 00:33:55.124
We talk about eventually, right, this high pressure, sheer stress being exerted
00:33:55.124 --> 00:33:57.284
on the aortic walls leading to,
00:33:57.804 --> 00:34:03.754
damage and eventual weakening, right, of that blood vessel that leads to things
00:34:03.754 --> 00:34:08.484
like mucoid accumulation, So literally mucus and inflammation developing in
00:34:08.484 --> 00:34:11.619
the arterial walls, resulting from that constant,
00:34:12.147 --> 00:34:15.074
bombardment with those high pressures, right?
00:34:15.074 --> 00:34:17.814
We talk about changes in the smooth muscle layers, right?
00:34:17.814 --> 00:34:22.434
And dysfunction in those smooth muscle layers that lead to the generation of
00:34:22.434 --> 00:34:24.104
that smooth muscle, right?
00:34:24.104 --> 00:34:28.984
And the loss of the ability to control the diameter of those blood vessels and
00:34:28.984 --> 00:34:32.865
how it accommodates that stress that is being subjected to constantly,
00:34:33.237 --> 00:34:35.594
right? from that pressure.
00:34:36.238 --> 00:34:41.672
And then we also talk about fibrosis developing, right, in those vessels.
00:34:42.107 --> 00:34:46.424
And ultimately, the vessel wall is becoming more stiff and, again,
00:34:46.424 --> 00:34:51.624
less compliant and less able to accommodate the pressures that it is being subjected
00:34:51.624 --> 00:34:54.714
to, especially when we talk about high blood pressure.
00:34:54.714 --> 00:34:59.318
And ultimately, we end up with a situation where there is so much damage,
00:34:59.653 --> 00:35:04.355
right, and eventual weakening of those layers that the vessel can tear,
00:35:04.918 --> 00:35:10.957
leading to a, what we call a false lumen or tract that develops and ultimately can be catastrophic.
00:35:11.252 --> 00:35:15.664
Everything from, right, loss of blood volume in these layers and not able to
00:35:15.664 --> 00:35:17.388
get blood to our vital organs.
00:35:17.788 --> 00:35:22.534
But we also talk about complications such as things like cardiac tamponade,
00:35:22.534 --> 00:35:27.164
where blood accumulates around the heart and literally shuts it down to everything
00:35:27.164 --> 00:35:29.454
from complications from stroke, right?
00:35:29.454 --> 00:35:35.494
That blood vessel lumen being interrupted and the normal smooth blood flow through
00:35:35.494 --> 00:35:38.404
that vessel being disrupted to the point where there's more turbulent blood
00:35:38.404 --> 00:35:42.378
flow that leads to clot formation and sending that to,
00:35:42.901 --> 00:35:45.070
you know, regions including the brain.
00:35:45.587 --> 00:35:49.014
Thus, right, there are some individuals that have an eric dissection,
00:35:49.014 --> 00:35:53.104
but it comes off or presents as like a stroke-like syndrome.
00:35:53.964 --> 00:35:58.524
Because of blood clots that have been sent to other parts of the body or whole
00:35:58.524 --> 00:36:03.474
parts of the body not receiving enough blood flow and individuals maybe sometimes
00:36:03.474 --> 00:36:06.370
presenting with what we call limb ischemia.
00:36:07.084 --> 00:36:13.364
So it seems like the leg or your upper extremity is not getting enough blood
00:36:13.364 --> 00:36:18.234
supply because that distribution of blood has been disrupted because of the
00:36:18.234 --> 00:36:20.906
tear in that aortic wall.
00:36:21.494 --> 00:36:23.564
But I think we all get the image in our minds, right?
00:36:24.814 --> 00:36:30.244
This is not a complication that you want from longstanding hypertension and
00:36:30.244 --> 00:36:34.038
these other risk factors that can largely be controlled, Reed.
00:36:34.799 --> 00:36:38.463
Yeah, absolutely. It's like you said, it's all largely controlled.
00:36:38.463 --> 00:36:42.703
And so it's incredibly important to know your family history,
00:36:42.703 --> 00:36:45.804
know your risks, and get regular checkups.
00:36:46.291 --> 00:36:51.301
So yeah, let's talk about aortic dissections. There's essentially two different categories.
00:36:51.614 --> 00:36:54.783
But I think to talk about them a little bit deeper, we need to understand the
00:36:54.783 --> 00:37:01.007
anatomy of the aorta a little bit better. So the aorta is the main artery that
00:37:01.122 --> 00:37:04.699
all the blood that the heart is pumping out goes into.
00:37:05.122 --> 00:37:09.513
So you've got the ascending aorta, which goes up, that then turns into the arch
00:37:09.513 --> 00:37:13.087
of the aorta, which from the arch, it branches off into the.
00:37:13.801 --> 00:37:18.973
Carotid and subclavian arteries, which essentially supply all of the blood supply
00:37:18.973 --> 00:37:22.427
to the head, the brain, neck, arms, your upper body.
00:37:22.975 --> 00:37:27.053
And then the descending aorta goes down and branches out into all of the arteries
00:37:27.053 --> 00:37:32.216
that supply your lower body, your abdomen, your legs, everything else with blood.
00:37:32.529 --> 00:37:36.613
And so the ascending aorta is before all of these branches.
00:37:36.613 --> 00:37:40.833
And so it handles pretty much all of the blood flow that comes out of the heart.
00:37:40.833 --> 00:37:46.033
So you can imagine how much blood this aorta handles, how high the pressure
00:37:46.033 --> 00:37:50.303
is there, the expanding and contracting that it does with every pump of the
00:37:50.303 --> 00:37:55.329
heart, like you said, over 2.5 billion times in your lifetime.
00:37:55.904 --> 00:38:00.246
And so this is an incredibly, Yeah, it's an incredibly important part of the body.
00:38:00.705 --> 00:38:07.531
And with it being as incredibly important, there's also if things go wrong there, they can go very wrong.
00:38:07.926 --> 00:38:10.993
So there's this very quick. Exactly. Yeah. So there's the Stanford system,
00:38:10.993 --> 00:38:15.333
which divides aortic dissection into two categories, type A being all those
00:38:15.333 --> 00:38:16.860
that involve the ascending aorta.
00:38:17.435 --> 00:38:22.718
This is the most common and the most urgent, so it requires immediate emergency
00:38:22.718 --> 00:38:27.848
surgical procedures, open heart surgery essentially, and this is including graft
00:38:27.848 --> 00:38:30.968
replacement of the damaged section of the aorta, endovascular.
00:38:31.738 --> 00:38:34.518
Stent graft repair, or a hybrid approach
00:38:34.518 --> 00:38:37.967
using techniques from both graft replacement and stent graft repair.
00:38:38.453 --> 00:38:43.308
Type B aortic dissection are all those that do not involve the ascending aorta,
00:38:43.608 --> 00:38:48.345
so it can involve the aortic arch as long as the ascending aorta is spared.
00:38:48.850 --> 00:38:54.371
And these are often less serious. They may not require surgical procedure to treat.
00:38:54.910 --> 00:38:59.438
They can be treated sometimes with beta blockers and other medications that
00:38:59.438 --> 00:39:02.728
would then lower your blood pressure and your heart rate, essentially lowering
00:39:02.728 --> 00:39:04.715
the pressure on that tear there.
00:39:05.046 --> 00:39:10.008
More severe ones may require surgery. Ideally, endovascular stent graft repair,
00:39:10.008 --> 00:39:14.630
something a little bit less invasive and can be done laparoscopically.
00:39:15.887 --> 00:39:19.767
And I wouldn't say necessarily less severe as far as the type B.
00:39:20.658 --> 00:39:25.237
I mean, you know, definitely not an emergent surgical case where they're rushing
00:39:25.237 --> 00:39:29.007
you to the operating room. And as Reed was saying, right, with the type A doing
00:39:29.007 --> 00:39:33.882
open heart surgery and putting you on cardiac bypass and things like that.
00:39:34.288 --> 00:39:38.517
But it still is very serious. And the reason being is that not only does it
00:39:38.517 --> 00:39:41.659
suck for the patient, because a lot of times patients are really uncomfortable
00:39:41.873 --> 00:39:46.820
feeling this, but the damage can propagate, meaning that tear in the wall.
00:39:47.013 --> 00:39:51.447
If you think of it like a zipper or even, you know, let's say even thinking
00:39:51.447 --> 00:39:53.077
about the garden hose analogy, right?
00:39:53.077 --> 00:39:56.747
You tear the garden hose and let's say you're manipulating it or you're running
00:39:56.747 --> 00:40:00.987
water through it, right? The pressure from inside that with the fluid flowing
00:40:00.987 --> 00:40:05.576
inside, it can propagate that disruption, meaning it can worsen that tear.
00:40:05.802 --> 00:40:09.777
That's why the blood pressure control is so clutch and the heart rate control
00:40:09.777 --> 00:40:13.857
with the beta blockers and other medications is so important because the longer
00:40:13.857 --> 00:40:16.901
that the person has an elevated blood pressure
00:40:17.337 --> 00:40:21.801
or even an elevated heart rate, which is typical for somebody that is very uncomfortable
00:40:22.126 --> 00:40:25.247
and suffering serious complication like this, right?
00:40:25.247 --> 00:40:28.437
The more that their blood pressure is elevated, the more their heart rate is
00:40:28.437 --> 00:40:33.482
elevated, that injury can propagate, meaning that a tear in the vessel wall,
00:40:33.963 --> 00:40:35.444
can continue and it can put.
00:40:36.036 --> 00:40:42.137
Those other organs at risk, even if it is type B and going down into the descending aorta, right?
00:40:42.137 --> 00:40:45.107
That's how individuals can end up with things like limb ischemia,
00:40:45.107 --> 00:40:48.672
where one of their legs might not be getting enough blood supply,
00:40:49.107 --> 00:40:52.091
or gut ischemia even, where the.
00:40:52.694 --> 00:40:57.389
You know, intestines and some of our vital gastrointestinal organs are not getting
00:40:57.389 --> 00:41:00.502
enough blood supply. And we have literally the gut dying off,
00:41:01.037 --> 00:41:04.793
right? Because of ischemia or lack of blood supply to those organs.
00:41:05.240 --> 00:41:09.139
Like this is, I'm sorry, and I know you didn't mean to not minimize the severity,
00:41:09.519 --> 00:41:15.049
but I have a clear picture of like, this is something that is in many cases,
00:41:15.049 --> 00:41:17.399
unfortunately, catastrophic, right?
00:41:17.399 --> 00:41:22.147
Where one, you know, you make it to the hospital live, that is fortunate,
00:41:22.542 --> 00:41:26.344
but it's something that we need to, you know, identify and diagnose,
00:41:26.756 --> 00:41:29.553
which can be challenging. That's a whole other conversation.
00:41:30.156 --> 00:41:34.559
But then, you know, I think really going back to sort of what we hoped was an
00:41:34.559 --> 00:41:39.861
opportunity in this program and talking about this was prevention.
00:41:40.453 --> 00:41:44.109
Like, we don't want you to get to this point, you know, especially if we're
00:41:44.109 --> 00:41:48.609
talking about modifiable risk factors, things like hypertension,
00:41:48.899 --> 00:41:52.429
things like smoking, cigarette smoking, which I think we've already,
00:41:53.079 --> 00:41:56.779
I think we did a decent job, but we tried, Reed, right, illustrating sort of
00:41:56.779 --> 00:42:00.119
what has happened from a pathophysiologic level, right?
00:42:00.119 --> 00:42:03.551
What is happening to these blood vessels as they're being bombarded with pressure.
00:42:03.929 --> 00:42:06.759
But just imagine that you got uncontrolled high blood pressure bombarding that
00:42:06.759 --> 00:42:08.729
blood vessel second to second.
00:42:09.380 --> 00:42:12.979
Right. But then add to that, you smoke cigarettes and now you have all of these,
00:42:13.461 --> 00:42:18.818
compounds, these chemicals that add additional insult to injury already.
00:42:19.295 --> 00:42:23.098
Right. And further denude or break down those blood vessel walls.
00:42:23.336 --> 00:42:26.023
We're just talking about a setup for catastrophe. Right.
00:42:26.651 --> 00:42:29.372
And that's something that we want to avoid as much as we can.
00:42:29.761 --> 00:42:32.410
Yeah, absolutely. Because it's harder treating your dissection.
00:42:33.366 --> 00:42:35.610
You come with a dissection, getting you to the operating room,
00:42:35.610 --> 00:42:39.170
whether you got a type A or controlling your blood pressure with beta blockers.
00:42:39.170 --> 00:42:42.470
And your heart rate and giving you all these medications and controlling your
00:42:42.470 --> 00:42:47.400
pain, right? If we can just take that off the table by focusing on these modifiable
00:42:47.400 --> 00:42:52.731
risk factors that lead up to dissection, like if we can avoid this, that's the thing.
00:42:53.056 --> 00:42:54.380
You do not want to be in our emergency
00:42:54.380 --> 00:42:57.557
department with this or anybody's emergency department with this.
00:42:57.900 --> 00:43:01.900
Exactly. And thank you, Mo, for making that distinction that type B is still
00:43:01.900 --> 00:43:05.603
incredibly urgent, can be extremely bad.
00:43:06.027 --> 00:43:10.710
Type A obviously being something that requires immediate surgery,
00:43:10.710 --> 00:43:15.100
immediate open heart surgery, cardiac bypass, they're going to be in there for a while.
00:43:15.442 --> 00:43:20.970
Type B may not require that, but you can see how interrelated these two are
00:43:20.970 --> 00:43:24.209
in terms of seriousness when you look at the numbers.
00:43:24.760 --> 00:43:31.580
So following prompt surgical repair of type A dissection, in-hospital mortality is about 15% to 30%.
00:43:31.998 --> 00:43:35.940
And these are people that have gone to the hospital, immediately had prompt
00:43:35.940 --> 00:43:40.508
surgical repair, they still die 15% to 30% of the time.
00:43:41.007 --> 00:43:46.609
Five-year survival rate after this is 70% to 80%, 10-year survival is 50% to 60%.
00:43:47.092 --> 00:43:51.250
When we talk about type B aortic dissections that are medically managed and
00:43:51.650 --> 00:43:56.211
they have an in-hospital mortality rate of around 10-15%.
00:43:56.594 --> 00:44:02.353
So that's still extremely high for cases where they've gotten to the hospital right away.
00:44:02.603 --> 00:44:09.313
It's been very prompt. 10-15% is still really high for a rate of mortality.
00:44:09.661 --> 00:44:12.808
The rate for patients is complicated. You know what we're into though?
00:44:14.561 --> 00:44:20.441
Oh, real fast. The thing is, this is all improved over the last few decades.
00:44:20.807 --> 00:44:24.305
These are quote unquote good numbers from where we used to be where people would
00:44:24.305 --> 00:44:30.095
just, right, you know, catastrophically just die or be severely disabled because
00:44:30.095 --> 00:44:32.188
there was not as much that could be done.
00:44:32.450 --> 00:44:35.715
Like we are in a different era where we can do a lot for patients with aortic
00:44:35.715 --> 00:44:39.694
dissection, but you can see that, right, still the outcomes are still,
00:44:40.321 --> 00:44:42.887
yeah, could be better. Let's say that. Yeah, absolutely.
00:44:43.265 --> 00:44:46.475
And better as in, let's prevent this entirely.
00:44:46.910 --> 00:44:49.985
For those with type B dissections that are not promptly treated,
00:44:49.985 --> 00:44:52.808
the mortality rate is about 30 to 40%.
00:44:53.775 --> 00:44:58.485
The five-year survival rate is approximately 75 to 80%. So slightly higher than
00:44:58.485 --> 00:45:02.538
70 to 80%, but still abysmally low.
00:45:02.735 --> 00:45:06.365
And not only that, those who do survive aortic dissection, like you mentioned,
00:45:06.365 --> 00:45:10.188
often experience decreased quality of life, reduced functional status.
00:45:10.612 --> 00:45:15.018
It's extremely common to have persistent pain reduced exercise capacity,
00:45:15.483 --> 00:45:20.355
and along with that anxiety and depression because i don't think that the mental
00:45:20.355 --> 00:45:22.621
toll of these kinds of conditions is
00:45:22.952 --> 00:45:27.555
spoken about as much but the fact that you have reduced quality of life reduced
00:45:27.555 --> 00:45:32.475
mobility you're thinking about the next catastrophic event potentially happening
00:45:32.475 --> 00:45:35.200
that can all lead to a lot of anxiety and depression,
00:45:35.688 --> 00:45:43.065
and knowing that you need to get out and exercise or do things or change lifestyle
00:45:43.065 --> 00:45:46.515
behaviors in order to reduce your risk of a future event.
00:45:46.515 --> 00:45:52.580
But also after suffering an event, not being able to exercise very much, being very sedentary.
00:45:52.981 --> 00:45:58.185
I think those all play a large factor into, yeah, just like the overall mental
00:45:58.185 --> 00:45:59.767
toll that it takes on a person. Yeah.
00:46:01.694 --> 00:46:06.360
No facts, man. And so I think I think folks got their our drift right as far
00:46:06.360 --> 00:46:11.597
as why we really held the best treatment for this is just entirely preventing it.
00:46:12.205 --> 00:46:17.210
And it does not. Right. I think that is the opportunity here is that there's
00:46:17.210 --> 00:46:22.650
a lot of considering the extent of surgery, as we just discussed.
00:46:22.650 --> 00:46:28.661
And being managed with antihypertensives and stuff when you've suffered an aortic dissection.
00:46:29.350 --> 00:46:34.090
I think, Reed, nobody has to agree with me on this, but I think it's much lower
00:46:34.090 --> 00:46:37.970
hanging fruit when we talk about the things we can do as far as prevention.
00:46:37.970 --> 00:46:42.240
Yeah, absolutely. And I just want to talk about it one more time that Lindsey
00:46:42.240 --> 00:46:48.468
Graham's father died when Lindsey was in his 20s when the father was 68 due to heart attack.
00:46:48.874 --> 00:46:52.510
And so this is something that Lindsey probably knew and was on his radar since
00:46:52.510 --> 00:46:56.333
he was in his 20s, that he had a family history of cardiovascular disease.
00:46:56.757 --> 00:47:00.670
I have no idea how they went about managing it. You'd think being that high
00:47:00.670 --> 00:47:05.865
up in government, you'd have regular checkups and have some of the best doctors in the world.
00:47:06.405 --> 00:47:11.610
But people are difficult to change. And so unless somebody truly wants to change,
00:47:11.610 --> 00:47:13.261
they're often not going to.
00:47:13.806 --> 00:47:17.420
But yeah, I can only imagine that there were many conversations,
00:47:17.420 --> 00:47:22.582
at least with his doctors, about his risk for some sort of event like this.
00:47:22.942 --> 00:47:26.820
And so, yeah, I think the warning signs, you should have seen him coming,
00:47:27.273 --> 00:47:29.640
at least from a doctor check-in point.
00:47:29.640 --> 00:47:33.990
A lot of times these things may be sleeper kind of things. And in hindsight,
00:47:33.990 --> 00:47:38.100
you'll notice, okay, yeah, I had a history of atherosclerosis,
00:47:38.100 --> 00:47:39.939
which put me at risk to an event like this.
00:47:40.351 --> 00:47:44.200
But knowing your family history, I think it's oftentimes a superpower because
00:47:44.200 --> 00:47:45.558
you share the same genetics.
00:47:46.228 --> 00:47:50.170
You share the same risk factors. You grew up in a similar environment,
00:47:50.170 --> 00:47:52.091
too. You know what you've been exposed to.
00:47:52.590 --> 00:47:58.594
And so, yeah, knowing your family history can be incredibly powerful in terms of prevention.
00:47:59.485 --> 00:48:04.437
And, you know, not to really comment on Senator Graham's, right, I don't know.
00:48:04.857 --> 00:48:07.797
I mean, I don't know if his blood pressure was uncontrolled.
00:48:07.797 --> 00:48:11.347
I don't think anybody knows. And who knows if that'll ever come to light as
00:48:11.347 --> 00:48:16.941
far as, you know, his overall health status and how he regarded his health.
00:48:17.443 --> 00:48:22.617
And, I mean, as you said, right, even if he had the best access to care in the
00:48:22.617 --> 00:48:28.641
world, I think it just shows how, right, this can technically happen to anyone. Yeah.
00:48:29.111 --> 00:48:32.707
And and Senator Graham, maybe he did take his medications every day.
00:48:32.707 --> 00:48:36.935
Maybe he did his best to engage in physical activity to reduce his risk.
00:48:37.440 --> 00:48:44.074
You know, we can't really say what you know how he engaged this or did things to prevent it.
00:48:44.539 --> 00:48:47.197
But what we are doing is just letting you know that there are things that we
00:48:47.197 --> 00:48:51.458
can do to, right, lower our risk of suffering a complication like this.
00:48:51.725 --> 00:48:55.587
And who knows, maybe it was just he came from a long trip overseas doing what
00:48:55.587 --> 00:48:59.447
I would imagine is a very stressful thing that is happening over in Ukraine.
00:48:59.447 --> 00:49:03.109
And maybe that was the thing that spiked this pressure at that time and led to this.
00:49:03.510 --> 00:49:07.087
But just understand, ladies and gentlemen, that there are things that we can
00:49:07.087 --> 00:49:11.077
do to lower our risk. And a lot of it boils down to we had a conversation with
00:49:11.077 --> 00:49:12.506
Dr. Donald Lloyd-Jones.
00:49:12.737 --> 00:49:16.487
He's the director of the Framingham Center for Population and Prevention Science
00:49:16.899 --> 00:49:19.664
and a former president of the American Heart Association.
00:49:20.076 --> 00:49:24.607
And we had a whole talk about lysoscentral aid, right? And basically eight things
00:49:24.607 --> 00:49:28.977
that we can do to reduce our risk of cardiovascular disease as a whole.
00:49:28.977 --> 00:49:33.038
That's everything from heart attacks, strokes, complications like aortic dissection.
00:49:33.630 --> 00:49:37.214
And these are the things we need to be mindful of, right?
00:49:37.214 --> 00:49:40.984
We need to be mindful of things like eating better. So eating more fresh fruits
00:49:40.984 --> 00:49:45.654
and vegetables, whole grains, lean proteins, being more active,
00:49:45.654 --> 00:49:50.471
right? Two and a half hours of moderate activity or 75 minutes of vigorous activity each week.
00:49:50.760 --> 00:49:53.254
But I'm not going to, you don't got to remember all of this right now because
00:49:53.254 --> 00:49:56.164
it's in the previous show and it's in our show notes, right?
00:49:56.164 --> 00:49:59.497
Getting healthy sleep, healthy amounts of sleep, quitting smoking,
00:49:59.817 --> 00:50:05.864
managing our body weight, right? Making sure that our levels of non-HDL cholesterol
00:50:05.864 --> 00:50:09.799
are controlled, right? AKA bad cholesterol. We want to control that.
00:50:10.217 --> 00:50:13.568
Blood pressure control, right? If there's anything to take away from this,
00:50:13.881 --> 00:50:17.172
it is that we really need to make sure that, right,
00:50:17.602 --> 00:50:22.984
we have access to a primary care physician or provider and that our blood pressure
00:50:22.984 --> 00:50:27.624
is uncontrolled because chief among them, the major risk factor in all of this,
00:50:27.624 --> 00:50:30.849
right, is blood pressure not be in control.
00:50:31.128 --> 00:50:34.114
On top of all these other things, blood sugar control, right,
00:50:34.114 --> 00:50:37.078
making sure we are not developing things like diabetes.
00:50:37.484 --> 00:50:41.455
But a lot of these things we can modify and control.
00:50:41.792 --> 00:50:45.826
And the more we do so, the less likely we are to suffer a complication like this.
00:50:46.441 --> 00:50:50.784
Now, as we close, you know, again, And it's just one of those things,
00:50:50.784 --> 00:50:56.044
as we reflect on the life and legacy of Senator Graham, regardless of whether
00:50:56.044 --> 00:51:01.029
you agree with his politics or not, I think he would be...
00:51:01.755 --> 00:51:05.383
In terms of us discussing this and passing from something like this,
00:51:05.620 --> 00:51:09.486
I think it would have been a proponent of folks being empowered with information
00:51:09.486 --> 00:51:14.736
that, hey, this is something that we can reduce our risk of suffering by paying
00:51:14.736 --> 00:51:16.612
attention to those factors.
00:51:18.121 --> 00:51:21.296
And is everybody going to avoid it, Reed? That is not something that we could
00:51:21.296 --> 00:51:25.580
say on this program. I would argue that there are going to be people that suffer this complication.
00:51:25.953 --> 00:51:27.936
And that's why when my family calls me, they're like, man, yo,
00:51:27.936 --> 00:51:30.926
Mo, I got this chest pain. What do I do about it?
00:51:31.386 --> 00:51:34.276
Something is uncomfortable enough for you to call me about it,
00:51:34.276 --> 00:51:39.116
especially chest pain, you need to go to the emergency department and be evaluated
00:51:39.116 --> 00:51:40.615
to make sure that you are safe.
00:51:40.993 --> 00:51:44.673
Are they going to send you for a CT angiogram to look for a dissection?
00:51:44.824 --> 00:51:48.036
It depends on what's going on, what your signs and symptoms are like,
00:51:48.036 --> 00:51:49.173
what your risk factors are like.
00:51:49.601 --> 00:51:52.886
But anytime you're uncomfortable, whether it's abdominal pain,
00:51:52.886 --> 00:51:58.187
severe headache, being evaluated in an acute care setting, emergency department,
00:51:58.589 --> 00:52:01.756
Some folks go to urgent care and they might very well refer you to an emergency
00:52:01.756 --> 00:52:03.476
department to be evaluated.
00:52:03.476 --> 00:52:05.976
But I want you to take those symptoms seriously.
00:52:06.458 --> 00:52:09.413
But on a prevention standpoint, there's a lot that can be done,
00:52:09.767 --> 00:52:14.498
as we stated, to reduce our risk of suffering a devastating outcome like this.
00:52:14.829 --> 00:52:18.606
And we wanted to take that opportunity to share that with you all.
00:52:18.606 --> 00:52:23.306
Yeah, absolutely. Thank you for bringing that up, Mo, because outside of prevention,
00:52:23.306 --> 00:52:25.126
early intervention is the best.
00:52:25.486 --> 00:52:29.336
So taking symptoms seriously i'm sure you see it all the time where people come
00:52:29.336 --> 00:52:32.246
in and they're like yeah i've been having chest pain for the past week and you
00:52:32.246 --> 00:52:34.814
figure out oh you're it's a heart attack yeah,
00:52:35.412 --> 00:52:41.016
and so i think getting in to see a doctor whether it's in urgent care or the
00:52:41.016 --> 00:52:46.662
er or whatever it is as soon as possible early intervention is always going to be better.
00:52:47.509 --> 00:52:50.575
Facts, man. And I've definitely had patients that have had a dissection for
00:52:50.575 --> 00:52:55.015
like days that is like, you finally came in and you were, you couldn't sleep
00:52:55.015 --> 00:52:56.686
last night because of this tearing pain.
00:52:57.168 --> 00:53:01.675
Like, you know, fortunately those people were okay. At least when they presented,
00:53:01.675 --> 00:53:05.695
you know, they were still alive, but this is something that can evolve rather quickly.
00:53:06.055 --> 00:53:09.115
And so it's not one of those things you want to put to the wayside.
00:53:09.115 --> 00:53:12.725
If it's enough to distract you from what you're doing and you got to pay attention
00:53:12.725 --> 00:53:16.195
to any sort of discomfort like that, whether it's in the back,
00:53:16.195 --> 00:53:19.755
the chest, abdomen, headache, whatever, as we discussed, like you need to be
00:53:19.755 --> 00:53:23.275
evaluated in an emergency setting. All right. I'm not going to belabor the point, man.
00:53:25.234 --> 00:53:29.530
I want to thank you all. Well, first and foremost, Reid, thank you for jumping on.
00:53:30.029 --> 00:53:33.309
Always. Always a pleasure talking with you, man, about this stuff.
00:53:33.669 --> 00:53:36.995
And I also want to thank our listening audience for listening to this program.
00:53:36.995 --> 00:53:40.954
And in advance, we thank you for spreading this information with anyone that will listen.
00:53:41.569 --> 00:53:48.239
Ladies and gentlemen, as always, this show is dedicated to the memory of Miss Gloria Thomas.
