In community-dwelling heart failure patients, mortality remains high with a significant proportion of non-cardiovascular deaths, particularly among those with preserved ejection fraction.
Community subjects with HF experience a persistently high mortality and a large proportion of deaths are non-cardiovascular. Subjects with preserved EF have less cardiovascular disease before death, are less likely to experience cardiovascular deaths than those with reduced EF and the proportion of cardiovascular deaths declined over time.
Henkel et al. (Thu,) studied this question.
