Although the syndrome of heart failure with preserved systolic function may occur in up to 40% of all heart failure patients, the clinical, angiographic characteristics, and long-term outcomes of these patients are poorly understood. We prospectively evaluated 2,498 consecutive patients with New York Heart Association class II to IV symptoms and ejection fractions of >40%, who underwent cardiac catheterization between January 1984 and December 1996 at Duke University Medical Center. The median age for the entire cohort was 63 years; 25% of the population was >71 years old. In addition, 55% of the patients were women, 65% had ischemic heart disease, 28% had a history of diabetes, and 62% had a history of hypertension. The median ejection fraction was 58%. One third of the patients had multivessel disease by coronary angiography. The overall 5-year mortality of the total population was 28%. The independent predictors of mortality (p <0.05) using a multivariable Cox proportional hazard model were age, class IV symptoms, ejection fraction, coronary artery disease index, diabetes, peripheral vascular disease, and minority ethnic group. Heart failure with preserved systolic function is characterized by unique clinical and angiographic characteristics associated with a 5-year mortality rate of 28%. Furthermore, several clinical and angiographic characteristics are predictive of long-term survival.
