0156: Heart failure in the elderly: comparison between reduced ejection fraction and preserved ejection fraction

Abstract

Heart failure is a common problem in elderly people. In the elderly population, heart failure with preserved ejection fraction (HFPEF) has been increasingly recognized. The aim of this study was to compare clinical features and clinical outcomes between HFPEF and HFREF in patients older than 65 years. We enrolled 30 patients over 65 years old, who were admitted for heart failure between April 2009 and February 2010. We retrospectively analysed the clinical features including laboratory data and echocardiography parameters. In 19 patients (63%) left ventricular ejection fraction was preserved. Acute pulmonary edema (74% vs 27%) is the most frequent presentation in patients with HFPEF. Those patients have thicker left ventricular wall (68% vs 27%). The ischemic heart diseases as background disease is more frequent in HFREF (46% vs 5, 2%). There was no difference in short-term outcomes between HFPEF and HFREF. Our study has shown that more than the half of the CHF patients over 65 years of age had HFPEF. Left ventricular hypertrophy was one of the risk factors for HFPEF, and the short-term outcomes of HFPEF in this population were not different from that of HFREF.
