Epidemiology of Heart Failure:
The Need for Sex Specific Data
Sharon A. Hunt, MD
Stanford University, California
INTRODUCTION
There is actually some good data on
gender specific epidemiology in
heart failure*
*See (among others): Rosamond et al Heart
disease and stroke statistics—2008 update: a
report from the AHA statistics committee and
stroke statistics subcommittee. Circ
2008;117:e25-146.
HEART FAILURE ITSELF APPEARS TO HAVE
DIFFERENT EPIDEMIOLOGIC CHARACTERISTICS
IN MEN AND WOMEN, ATTRIBUTABLE TO…

Age.
Women older at onset

Ventricular function.
Systolic more often preserved in women

Cause of HF.
Less often ischemic in women.

Survival
Overall better for women

Hsich, E. M. et al. J Am Coll Cardiol 2009;54:491-498
Better LVEF, more CHF
 Despite having a more preserved LV ejection fraction
than men, women have higher rates of heart failure,
likely reflecting differences in LV modeling and
incidence of diastolic heart failure in women

Overall, however, HF is getting more
prevalent and costing more
REASONS INCLUDE
Increasing survival post-MI
Better therapy prolonging lives
“Ageing” of the population

Cost is Astronomical
Estimated direct and indirect cost of
HF in the US alone for the year 2008
$34.8 BILLION
Despite these striking epidemiological
differences in HF between the sexes…
Most clinical trials have not planned to
prospectively analyze the female
cohort or enroll any certain
percentage of women.
Enrollment of Women in NHLBI RCTs
Kim et al. J Am Coll Cardiol 2008;52:672-675
Mean percent of
women enrolled in all
trials (27%) vs. mean
percent of all patients
with CVD who were
women (53%)
Some data have been teased out
with meta-analyses:
ACE INHIBITORS
Probably work as well in women as
in men, at least for treatment
 Possibly not for prevention of HF

Effect of angiotensin-converting enzyme inhibitors on mortality in male and
female patients with heart failure (random effects pooled estimate)

Some data have been teased out
with meta-analyses:
BETA BLOCKERS
Similar meta-analysis strongly
suggests similar reduced mortality
when men and women with
symptomatic HF treated with beta
blockers
There are, of course, no prevention
Trials with beta blockers
Some data have been teased out with
post-hoc analyses:
ALDOSTERONE ANTAGONISTS
Both RALES and EPHESUS show a total mortality
benefit for women with systolic HF
HYDRALAZINE/NITRATES
A-HeFT was stopped prematurely for
benefit in both men and women
Some data have been teased out with
post-hoc analyses:
DEVICE THERAPY
CRT and ICD’S
Few of the large multicenter trials
have reported sex-specific data
Post-hoc analyses of the few women
enrolled suggest that they do benefit
