Black bars show percent prevalence; lower portion of the bars show the proportion of cases associated with preserved systolic function. LV = left ventricular.

Where more than one ejection fraction measurement was available, the most recent one was used. Fifty-one percent of men but only 28% of women had a left ventricular ejection fraction <40%.
