Abstract
We found that the prevalence of heart failure with preserved ejection fraction among patients with a discharge diagnosis of heart failure increased significantly from 1987 to 2001. The prevalence of hypertension, atrial fibrillation, and diabetes increased during the study period, while the prevalence of coronary disease remained stable. Patients with preserved ejection fraction fared slightly better than patients with reduced ejection fraction. However, although survival improved during the study period among patients with reduced ejection fraction, it did not improve among patients with preserved ejection fraction.
