Aims: This study was designed to identify the characteristics and long-term prognosis of heart failure with preserved ejection fraction (HFPEF) in patients hospitalized for a first episode of HF.
Methods and results: Consecutive patients (n = 799) hospitalized for a first episode of HF during 2000 in the Somme department (France) were recruited. EF was available in 662 (83%) patients, representing the study population. Patients with HFPEF (55.6% of cases) were significantly older, with a high proportion of women. During the 5 year follow-up, 370 patients (56%) died. Patients with HFPEF had a significantly lower 5 year survival than the age- and sex-matched general population (43 vs. 72%). Five year survival rates were not significantly different in patients with preserved and reduced EF (43 vs. 46%; P = 0.95). Both groups had similar relative 5 year survival rates compared with the general population. Multivariable analysis identified age, stroke, chronic obstructive pulmonary disease, cancer, diabetes, low glomerular filtration rate, and hyponatraemia as independent predictors of 5 year mortality in patients with HFPEF.
Conclusions: Heart failure with preserved ejection fraction has a poor prognosis, comparable with that of HF with reduced EF, with a 5 year survival rate after a first episode of 43% and a high excess mortality compared with the general population.
