Abstract

Background: Left ventricle diastolic dysfunction is attracting increasing attention of one of the etiologies of chronic heart failure (CHF). Methods and Results: The study sample included 560 patients with CHF who were hospitalized during the 5-year period. They were classified into 2 groups according to the left ventricular ejection fraction (LVEF): reduced group (LVEF<50%, n=431); or preserved group (LVEF≥50%, n=129). The degree of cardiac symptoms did not differ between the 2 groups; however, no difference was found between the 2 groups in the mortality rate (P=0.898), and readmission rates (P=0.674). The results of a multivariate analysis using a Cox proportional hazards model to identify predictors of the prognosis of heart failure revealed no difference in prognosis according to the presence/absence of decreased LVEF, whereas renal dysfunction and anemia were identified as significant prognostic determinants. Also, in the reduced group, the administration of angiotensin-converting enzyme inhibitors (ACE-I) and/or angiotensin II receptor blockers (ARB), β-blockers reduced mortality. In the preserved group, ACE-I and/or ARB administration reduced mortality, whereas β-blockers did not. Conclusion In the present study, the likelihood of LVEF influencing prognosis was considered to be low, with the contribution of non-cardiac factors such as renal function and anemia concluded to be greater.
