Abstract
Heart Failure with preserved Ejection Fraction (HFpEF), like other heart failure syndromes, is
heterogeneous in etiology and pathophysiology, rather than a single disease. HFpEF may account
for about half of all patients with heart failure. Patients have symptoms and signs of HF with
normal or near normal left ventricular EF (LV EF>50 %). The classical risk factors for
developing HFpEF include advanced age and co-morbidities, notably hypertension, atrial
fibrillation, and the metabolic syndrome. When complicated by increasing congestion requiring
hospital admission, the prognosis is poor; 30% or more of such patients will die within 1 year
(nearly two-thirds die from cardiovascular causes). Patients with chronic stable symptoms have a
better prognosis. Patients with HFpEF represent an important group of patients presenting in
clinical practice with HF. Overall, it appears that patients with HFpEF are at lower risk of death
than patients with HFrEF, although mortality remains high in both groups. Application of the
same therapeutic hypotheses that have been successfully utilized among patients with HFrEF
have not been demonstrated to result in improved survival.
