Figure 4 Distribution of left ventricular ejection fraction measured within 12 months of the survey among women (n = 2,048; 41% of total enrolled) and men (n = 3,249; 57% of total enrolled) enrolled in the EuroHeart Failure survey. 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%.
