[Survival for 48 months, survival predictors in patients with chronic heart failure of ischemic origin with systolic left ventricular dysfunction and preserved left ventricular ejection fraction].

354 patients with chronic heart failure (CHF) of ischemic origin with systolic left ventricular dysfunction (SLVD) and 227 patients with preserved left ventricular ejection fraction (PLVEF) were examined. This study was aimed at the studying of comparative aspect of survival of patients with CHF and SLVD and with PLVEF for 48 months of observation, and the studying of nonsurvival predictors. Survival of patients with PLVEF is significantly better compared with survival of patients with SLVD for 48 months (66% and 42% respectively). The most informative predictors of 48 month in patients with SLVD were: uric acid level (OR = 3,17), end-systolic volume (OR = 2,71), hemoglobin level (OR = 2,64), creatinine level (OR = 2,36), end-dyastolic volume (OR = 2,49), index of end-systolic volume (OR = 2,44). The most informative predictors in patients PLVEF were: cholesterol level (OR = 2,14) and distance of 6-minute walk (OR = 2,11).
