Surprising, but true: More women now die of heart disease than men, yet cardiovascular research has long focused on men. Pioneering doctor C. Noel Bairey Merz shares what we know and don't know about women's heart health -- including the remarkably different symptoms women present during a heart attack (and why they're often missed).

One out of two of you women
0
0
3000
00:18
will be impacted by cardiovascular disease
1
3000
2000
00:20
in your lifetime.
2
5000
3000
00:23
So this is the leading killer of women.
3
8000
4000
00:27
It's a closely held secret
4
12000
2000
00:29
for reasons I don't know.
5
14000
3000
00:32
In addition to making this personal --
6
17000
3000
00:35
so we're going to talk about your relationship with your heart
7
20000
2000
00:37
and all women's relationship with their heart --
8
22000
3000
00:40
we're going to wax into the politics.
9
25000
2000
00:42
Because the personal, as you know, is political.
10
27000
3000
00:45
And not enough is being done about this.
11
30000
3000
00:48
And as we have watched women
12
33000
2000
00:50
conquer breast cancer
13
35000
2000
00:52
through the breast cancer campaign,
14
37000
2000
00:54
this is what we need to do now with heart.
15
39000
3000
00:57
Since 1984,
16
42000
2000
00:59
more women die in the U.S. than men.
17
44000
4000
01:03
So where we used to think of heart disease
18
48000
3000
01:06
as being a man's problem primarily --
19
51000
3000
01:09
which that was never true,
20
54000
2000
01:11
but that was kind of how everybody thought in the 1950s and '60s,
21
56000
3000
01:14
and it was in all the textbooks.
22
59000
2000
01:16
It's certainly what I learned when I was training.
23
61000
3000
01:19
If we were to remain sexist, and that was not right,
24
64000
3000
01:22
but if we were going to go forward and be sexist,
25
67000
3000
01:25
it's actually a woman's disease.
26
70000
2000
01:27
So it's a woman's disease now.
27
72000
2000
01:29
And one of the things that you see
28
74000
2000
01:31
is that male line,
29
76000
2000
01:33
the mortality is going down, down, down, down, down.
30
78000
2000
01:35
And you see the female line since 1984,
31
80000
3000
01:38
the gap is widening.
32
83000
2000
01:40
More and more women, two, three, four times more women,
33
85000
3000
01:43
dying of heart disease than men.
34
88000
3000
01:46
And that's too short of a time period
35
91000
2000
01:48
for all the different risk factors that we know
36
93000
2000
01:50
to change.
37
95000
2000
01:52
So what this really suggested to us
38
97000
2000
01:54
at the national level
39
99000
2000
01:56
was that diagnostic and therapeutic strategies,
40
101000
4000
02:00
which had been developed in men, by men, for men
41
105000
3000
02:03
for the last 50 years --
42
108000
2000
02:05
and they work pretty well in men, don't they? --
43
110000
3000
02:08
weren't working so well for women.
44
113000
3000
02:11
So that was a big wake-up call
45
116000
2000
02:13
in the 1980's.
46
118000
2000
02:15
Heart disease kills more women
47
120000
3000
02:18
at all ages
48
123000
2000
02:20
than breast cancer.
49
125000
2000
02:22
And the breast cancer campaign --
50
127000
2000
02:24
again, this is not a competition.
51
129000
2000
02:26
We're trying to be as good as the breast cancer campaign.
52
131000
3000
02:29
We need to be as good as the breast cancer campaign
53
134000
3000
02:32
to address this crisis.
54
137000
2000
02:34
Now sometimes when people see this,
55
139000
2000
02:36
I hear this gasp.
56
141000
2000
02:38
We can all think of someone,
57
143000
2000
02:40
often a young woman,
58
145000
2000
02:42
who has been impacted by breast cancer.
59
147000
3000
02:45
We often can't think of a young woman
60
150000
2000
02:47
who has heart disease.
61
152000
2000
02:49
I'm going to tell you why.
62
154000
2000
02:51
Heart disease kills people,
63
156000
2000
02:53
often very quickly.
64
158000
2000
02:55
So the first time heart disease strikes in women and men,
65
160000
3000
02:58
half of the time it's sudden cardiac death --
66
163000
3000
03:01
no opportunity to say good-bye,
67
166000
2000
03:03
no opportunity to take her to the chemotherapy,
68
168000
2000
03:05
no opportunity to help her pick out a wig.
69
170000
3000
03:08
Breast cancer,
70
173000
2000
03:10
mortality is down to four percent.
71
175000
3000
03:13
And that is the 40 years
72
178000
2000
03:15
that women have advocated.
73
180000
4000
03:19
Betty Ford, Nancy Reagan stood up
74
184000
3000
03:22
and said, "I'm a breast cancer survivor,"
75
187000
2000
03:24
and it was okay to talk about it.
76
189000
2000
03:26
And then physicians have gone to bat.
77
191000
2000
03:28
We've done the research.
78
193000
2000
03:30
We have effective therapies now.
79
195000
2000
03:32
Women are living longer than ever.
80
197000
2000
03:34
That has to happen in heart disease, and it's time.
81
199000
3000
03:37
It's not happening, and it's time.
82
202000
3000
03:42
We owe an incredible debt of gratitude
83
207000
2000
03:44
to these two women.
84
209000
2000
03:46
As Barbara depicted
85
211000
2000
03:48
in one of her amazing movies, "Yentl,"
86
213000
4000
03:52
she portrayed a young woman
87
217000
2000
03:54
who wanted an education.
88
219000
3000
03:57
And she wanted to study the Talmud.
89
222000
2000
03:59
And so how did she get educated then?
90
224000
2000
04:01
She had to impersonate a man.
91
226000
2000
04:03
She had to look like a man.
92
228000
2000
04:05
She had to make other people believe that she looked like a man
93
230000
3000
04:08
and she could have the same rights
94
233000
2000
04:10
that the men had.
95
235000
2000
04:12
Bernadine Healy, Dr. Healy,
96
237000
3000
04:15
was a cardiologist.
97
240000
2000
04:17
And right around that time, in the 1980's,
98
242000
3000
04:20
that we saw women and heart disease deaths
99
245000
2000
04:22
going up, up, up, up, up,
100
247000
2000
04:24
she wrote an editorial
101
249000
2000
04:26
in the New England Journal of Medicine
102
251000
2000
04:28
and said, the Yentl syndrome.
103
253000
3000
04:31
Women are dying of heart disease,
104
256000
2000
04:33
two, three, four times more than men.
105
258000
3000
04:36
Mortality is not going down, it's going up.
106
261000
3000
04:39
And she questioned,
107
264000
2000
04:41
she hypothesized,
108
266000
2000
04:43
is this a Yentl syndrome?
109
268000
2000
04:45
And here's what the story is.
110
270000
2000
04:47
Is it because women don't look like men,
111
272000
3000
04:50
they don't look like that male-pattern heart disease
112
275000
3000
04:53
that we've spent the last 50 years understanding
113
278000
3000
04:56
and getting really good diagnostics
114
281000
2000
04:58
and really good therapeutics,
115
283000
2000
05:00
and therefore, they're not recognized for their heart disease.
116
285000
2000
05:02
And they're just passed.
117
287000
2000
05:04
They don't get treated, they don't get detected,
118
289000
3000
05:07
they don't get the benefit of all the modern medicines.
119
292000
3000
05:10
Doctor Healy then subsequently became
120
295000
2000
05:12
the first female director
121
297000
2000
05:14
of our National Institutes of Health.
122
299000
2000
05:16
And this is the biggest biomedical enterprise research
123
301000
3000
05:19
in the world.
124
304000
2000
05:21
And it funds a lot of my research.
125
306000
2000
05:23
It funds research all over the place.
126
308000
2000
05:25
It was a very big deal
127
310000
2000
05:27
for her to become director.
128
312000
2000
05:29
And she started,
129
314000
2000
05:31
in the face of a lot of controversy,
130
316000
2000
05:33
the Women's Health Initiative.
131
318000
2000
05:35
And every woman in the room here
132
320000
2000
05:37
has benefited from that Women's Health Initiative.
133
322000
2000
05:39
It told us about hormone replacement therapy.
134
324000
3000
05:42
It's informed us about osteoporosis.
135
327000
2000
05:44
It informed us about breast cancer, colon cancer in women.
136
329000
3000
05:47
So a tremendous fund of knowledge
137
332000
3000
05:50
despite, again,
138
335000
2000
05:52
that so many people told her not to do it,
139
337000
2000
05:54
it was too expensive.
140
339000
2000
05:56
And the under-reading was women aren't worth it.
141
341000
3000
05:59
She was like, "Nope. Sorry. Women are worth it."
142
344000
3000
06:02
Well there was a little piece of that Women's Health Initiative
143
347000
3000
06:05
that went to National Heart, Lung, and Blood Institute,
144
350000
2000
06:07
which is the cardiology part of the NIH.
145
352000
3000
06:10
And we got to do the WISE study --
146
355000
2000
06:12
and the WISE stands for Women's Ischemia Syndrome Evaluation --
147
357000
4000
06:16
and I have chaired this study for the last 15 years.
148
361000
2000
06:18
It was a study to specifically ask,
149
363000
3000
06:21
what's going on with women?
150
366000
2000
06:23
Why are more and more women dying
151
368000
2000
06:25
of ischemic heart disease?
152
370000
2000
06:27
So in the WISE, 15 years ago,
153
372000
3000
06:30
we started out and said, "Well wow, there's a couple of key observations
154
375000
3000
06:33
and we should probably follow up on that."
155
378000
2000
06:35
And our colleagues in Washington, D.C.
156
380000
3000
06:38
had recently published
157
383000
3000
06:41
that when women have heart attacks and die,
158
386000
3000
06:44
compared to men who have heart attacks and die --
159
389000
3000
06:47
and again, this is millions of people,
160
392000
2000
06:49
happening every day --
161
394000
3000
06:52
women, in their fatty plaque --
162
397000
2000
06:54
and this is their coronary artery,
163
399000
2000
06:56
so the main blood supply going into the heart muscle --
164
401000
2000
06:58
women erode,
165
403000
2000
07:00
men explode.
166
405000
3000
07:03
You're going to find some interesting analogies
167
408000
2000
07:05
in this physiology.
168
410000
2000
07:07
(Laughter)
169
412000
3000
07:10
So I'll describe the male-pattern heart attack first.
170
415000
3000
07:13
Hollywood heart attack. Ughhhh.
171
418000
2000
07:15
Horrible chest pain.
172
420000
2000
07:17
EKG goes pbbrrhh,
173
422000
2000
07:19
so the doctors can see this hugely abnormal EKG.
174
424000
3000
07:22
There's a big clot in the middle of the artery.
175
427000
2000
07:24
And they go up to the cath lab
176
429000
2000
07:26
and boom, boom, boom get rid of the clot.
177
431000
2000
07:28
That's a man heart attack.
178
433000
2000
07:30
Some women have those heart attacks,
179
435000
2000
07:32
but a whole bunch of women have this kind of heart attack,
180
437000
2000
07:34
where it erodes,
181
439000
2000
07:36
doesn't completely fill with clot, symptoms are subtle,
182
441000
3000
07:39
EKG findings are different --
183
444000
2000
07:41
female-pattern.
184
446000
2000
07:43
So what do you think happens to these gals?
185
448000
3000
07:46
They're often not recognized, sent home.
186
451000
2000
07:48
I'm not sure what it was. Might have been gas.
187
453000
3000
07:51
So we picked up on that
188
456000
2000
07:53
and we said, "You know, we now have the ability
189
458000
3000
07:56
to look inside human beings
190
461000
3000
07:59
with these special catheters called IVUS:
191
464000
2000
08:01
intravascular ultrasound."
192
466000
2000
08:03
And we said, "We're going to hypothesize
193
468000
3000
08:06
that the fatty plaque in women
194
471000
3000
08:09
is actually probably different,
195
474000
2000
08:11
and deposited differently, than men."
196
476000
2000
08:13
And because of the common knowledge
197
478000
4000
08:17
of how women and men get fat.
198
482000
2000
08:19
When we watch people become obese,
199
484000
4000
08:23
where do men get fat?
200
488000
3000
08:26
Right here, it's just a focal -- right there.
201
491000
4000
08:30
Where do women get fat?
202
495000
3000
08:33
All over.
203
498000
2000
08:35
Cellulite here, cellulite here.
204
500000
3000
08:38
So we said, "Look, women look like they're pretty good
205
503000
2000
08:40
about putting kind of the garbage away,
206
505000
2000
08:42
smoothly putting it away.
207
507000
2000
08:44
Men just have to dump it in a single area."
208
509000
3000
08:47
So we said, "Let's look at these."
209
512000
2000
08:49
And so the yellow is the fatty plaque,
210
514000
3000
08:52
and panel A is a man.
211
517000
2000
08:54
And you can see, it's lumpy bumpy.
212
519000
2000
08:56
He's got a beer belly in his coronary arteries.
213
521000
3000
08:59
Panel B is the woman, very smooth.
214
524000
2000
09:01
She's just laid it down nice and tidy.
215
526000
2000
09:03
(Laughter)
216
528000
2000
09:05
And if you did that angiogram,
217
530000
2000
09:07
which is the red,
218
532000
2000
09:09
you can see the man's disease.
219
534000
2000
09:11
So 50 years
220
536000
2000
09:13
of honing and crafting these angiograms,
221
538000
2000
09:15
we easily recognize
222
540000
2000
09:17
male-pattern disease.
223
542000
2000
09:19
Kind of hard to see that female-pattern disease.
224
544000
2000
09:21
So that was a discovery.
225
546000
2000
09:23
Now what are the implications of that?
226
548000
3000
09:26
Well once again, women get the angiogram
227
551000
2000
09:28
and nobody can tell that they have a problem.
228
553000
3000
09:31
So we are working now on a non-invasive --
229
556000
3000
09:34
again, these are all invasive studies.
230
559000
2000
09:36
Ideally you would love to do all this non-invasively.
231
561000
3000
09:39
And again, 50 years
232
564000
2000
09:41
of good non-invasive stress testing,
233
566000
2000
09:43
we're pretty good at recognizing male-pattern disease
234
568000
2000
09:45
with stress tests.
235
570000
2000
09:47
So this is cardiac magnetic resonance imaging.
236
572000
2000
09:49
We're doing this at the Cedars-Sinai Heart Institute
237
574000
3000
09:52
in the Women's Heart Center.
238
577000
2000
09:54
We selected this for the research.
239
579000
3000
09:57
This is not in your community hospital,
240
582000
2000
09:59
but we would hope to translate this.
241
584000
2000
10:01
And we're about two and a half years
242
586000
2000
10:03
into a five-year study.
243
588000
2000
10:05
This was the only modality
244
590000
2000
10:07
that can see the inner lining of the heart.
245
592000
2000
10:09
And if you look carefully, you can see
246
594000
2000
10:11
that there's a black blush right there.
247
596000
2000
10:13
And that is microvascular obstruction.
248
598000
3000
10:16
The syndrome, the female-pattern
249
601000
3000
10:19
now is called microvascular coronary dysfunction, or obstruction.
250
604000
4000
10:23
The second reason we really liked MRI
251
608000
3000
10:26
is that there's no radiation.
252
611000
2000
10:28
So unlike the CAT scans, X-rays, thalliums,
253
613000
3000
10:31
for women
254
616000
2000
10:33
whose breast is in the way
255
618000
2000
10:35
of looking at the heart,
256
620000
2000
10:37
every time we order something that has even a small amount of radiation,
257
622000
3000
10:40
we say, "Do we really need that test?"
258
625000
2000
10:42
So we're very excited about M.R.
259
627000
2000
10:44
You can't go and order it yet,
260
629000
2000
10:46
but this is an area of active inquiry
261
631000
2000
10:48
where actually studying women
262
633000
2000
10:50
is going to advance the field for women and men.
263
635000
3000
10:54
What are the downstream consequences
264
639000
3000
10:57
then, when female-pattern heart disease
265
642000
3000
11:00
is not recognized?
266
645000
2000
11:02
This is a figure
267
647000
2000
11:04
from an editorial that I published
268
649000
2000
11:06
in the European Heart Journal this last summer.
269
651000
3000
11:09
And it was just a pictogram
270
654000
2000
11:11
to sort of show
271
656000
2000
11:13
why more women are dying of heart disease,
272
658000
2000
11:15
despite these good treatments
273
660000
2000
11:17
that we know and we have work.
274
662000
3000
11:20
And when the woman
275
665000
2000
11:22
has male-pattern disease --
276
667000
2000
11:24
so she looks like Barbara in the movie --
277
669000
3000
11:27
they get treated.
278
672000
2000
11:29
And when you have female-pattern and you look like a woman,
279
674000
3000
11:32
as Barbara does here with her husband,
280
677000
3000
11:35
they don't get the treatment.
281
680000
2000
11:37
These are our life-saving treatments.
282
682000
2000
11:39
And those little red boxes are deaths.
283
684000
3000
11:42
So those are the consequences.
284
687000
2000
11:44
And that is female-pattern
285
689000
2000
11:46
and why we think the Yentl syndrome
286
691000
2000
11:48
actually is explaining
287
693000
2000
11:50
a lot of these gaps.
288
695000
3000
11:53
There's been wonderful news also
289
698000
3000
11:56
about studying women,
290
701000
2000
11:58
finally, in heart disease.
291
703000
2000
12:00
And one of the the cutting-edge areas
292
705000
2000
12:02
that we're just incredibly excited about
293
707000
2000
12:04
is stem cell therapy.
294
709000
2000
12:06
If you ask, what is the big difference
295
711000
3000
12:09
between women and men physiologically?
296
714000
2000
12:11
Why are there women and men?
297
716000
3000
12:14
Because women bring new life into the world.
298
719000
3000
12:17
That's all stem cells.
299
722000
2000
12:19
So we hypothesized
300
724000
2000
12:21
that female stem cells might be better
301
726000
3000
12:24
at identifying the injury,
302
729000
3000
12:27
doing some cellular repair
303
732000
2000
12:29
or even producing new organs,
304
734000
2000
12:31
which is one of the things
305
736000
2000
12:33
that we're trying to do with stem cell therapy.
306
738000
3000
12:36
These are female and male stem cells.
307
741000
3000
12:39
And if you had an injured organ,
308
744000
2000
12:41
if you had a heart attack
309
746000
2000
12:43
and we wanted to repair that injured area,
310
748000
3000
12:46
do you want those robust,
311
751000
2000
12:48
plentiful stem cells on the top?
312
753000
3000
12:51
Or do you want these guys,
313
756000
2000
12:53
that look like they're out to lunch?
314
758000
2000
12:55
(Laughter)
315
760000
2000
12:57
And some of our investigative teams
316
762000
3000
13:00
have demonstrated
317
765000
2000
13:02
that female stem cells --
318
767000
2000
13:04
and this is in animals
319
769000
2000
13:06
and increasingly we're showing this in humans --
320
771000
2000
13:08
that female stem cells,
321
773000
2000
13:10
when put even into a male body,
322
775000
2000
13:12
do better than male stem cells
323
777000
3000
13:15
going into a male body.
324
780000
2000
13:17
One of the things that we say
325
782000
2000
13:19
about all of this female physiology --
326
784000
2000
13:21
because again, as much as we're talking about women and heart disease,
327
786000
3000
13:24
women do, on average,
328
789000
2000
13:26
have better longevity than men --
329
791000
2000
13:28
is that unfolding the secrets of female physiology
330
793000
3000
13:31
and understanding that
331
796000
2000
13:33
is going to help men and women.
332
798000
3000
13:36
So this is not a zero-sum game in anyway.
333
801000
3000
13:39
Okay, so here's where we started.
334
804000
2000
13:41
And remember, paths crossed in 1984,
335
806000
4000
13:45
and more and more women
336
810000
2000
13:47
were dying of cardiovascular disease.
337
812000
2000
13:49
What has happened in the last 15 years with this work?
338
814000
3000
13:52
We are bending the curve.
339
817000
2000
13:54
We're bending the curve.
340
819000
2000
13:56
So just like the breast cancer story,
341
821000
3000
13:59
doing research, getting awareness going,
342
824000
3000
14:02
it works, you just have to get it going.
343
827000
3000
14:05
Now are we happy with this?
344
830000
2000
14:07
We still have two to three more women dying for every man.
345
832000
3000
14:10
And I would propose,
346
835000
2000
14:12
with the better longevity
347
837000
2000
14:14
that women have overall,
348
839000
2000
14:16
that women probably should theoretically do better,
349
841000
2000
14:18
if we could just get treated.
350
843000
2000
14:20
So this is where we are,
351
845000
3000
14:23
but we have a long row to hoe.
352
848000
2000
14:25
We've worked on this for 15 years.
353
850000
2000
14:27
And I've told you, we've been working on male-pattern heart disease
354
852000
3000
14:30
for 50 years.
355
855000
2000
14:32
So we're 35 years behind.
356
857000
2000
14:34
And we'd like to think it's not going to take 35 years.
357
859000
3000
14:37
And in fact, it probably won't.
358
862000
2000
14:39
But we cannot stop now.
359
864000
2000
14:41
Too many lives are at stake.
360
866000
3000
14:44
So what do we need to do?
361
869000
3000
14:47
You now, hopefully, have a more personal relationship
362
872000
2000
14:49
with your heart.
363
874000
2000
14:51
Women have heard the call
364
876000
2000
14:53
for breast cancer
365
878000
2000
14:55
and they have come out
366
880000
2000
14:57
for awareness campaigns.
367
882000
2000
14:59
The women are very good about getting mammograms now.
368
884000
3000
15:02
And women do fundraising.
369
887000
2000
15:04
Women participate.
370
889000
2000
15:06
They have put their money where their mouth is
371
891000
2000
15:08
and they have done advocacy and they have joined campaigns.
372
893000
3000
15:11
This is what we need to do with heart disease now.
373
896000
3000
15:14
And it's political.
374
899000
2000
15:16
Women's health, from a federal funding standpoint,
375
901000
3000
15:19
sometimes it's popular,
376
904000
2000
15:21
sometimes it's not so popular.
377
906000
3000
15:24
So we have these feast and famine cycles.
378
909000
2000
15:26
So I implore you
379
911000
2000
15:28
to join the Red Dress Campaign
380
913000
2000
15:30
in this fundraising.
381
915000
2000
15:32
Breast cancer, as we said,
382
917000
2000
15:34
kills women,
383
919000
2000
15:36
but heart disease kills a whole bunch more.
384
921000
3000
15:39
So if we can be as good as breast cancer
385
924000
2000
15:41
and give women this new charge,
386
926000
2000
15:43
we have a lot of lives to save.
387
928000
2000
15:45
So thank you for your attention.
388
930000
2000
15:47
(Applause)
