Abstract

Background: Little has been known about clinical features and prognosis of very old patients with heart failure with preserved ejection fraction (HFPEF). The aim of this study was to compare clinical features and clinical outcomes between HFPEF and heart failure with reduced ejection fraction (HFREF) in patients older than 80 years. Methods: We enrolled a total of 113 patients over 80 years old, who were admitted for heart failure between 2006 and 2009. We retrospectively analyzed the clinical features including laboratory data and echocardiography parameters. Results: In 53 patients (49%) left ventricular ejection fraction was preserved. The clinical characteristics and treatment between HFPEF and HFREF showed that anemia was one of the risk factors for HFPEF, and the long-term outcomes of HFPEF in this population were not different from that of HFREF. Conclusion: These results suggest that anemia is one of the important risk factors for HFPEF in the very elderly. © 2011 Japanese College of Cardiology.
