Why the study?
Does preserved ejection fraction compared to decreased ejection fraction predict mortality and quality of life in long-term survivors with heart failure?
Does preserved ejection fraction compared to decreased ejection fraction predict mortality and quality of life in long-term survivors with heart failure?
While HFpEF confers a modest survival advantage over HFrEF, long-term survivors experience similar functional decline and quality of life impairments regardless of ejection fraction.
Heart failure patients with preserved EF have a modest survival advantage compared with those with decreased EF, but health related QOL scores and functional decline in survivors are similar regardless of systolic function.
