The survival, clinical and echocardiographic variables and the predictors of c ardiovascular death were determined for a group of 168 patients(mean age 63±13 years; 65 females; mean left ventricular ejection fraction 32±10%) with restri ctive filling of the left ventricle and depressed systolic function after a mean follow-up period of 2.7±1 years. Shorter deceleration time(DT) of the mitral inflow was the only variable significantly different between survivors and nonsu rvivors(p< 0.05) and the only predictor of death found by multivariate logistic regression analysis(odds ratio 2.2, 95%confidence interval 1.7-3.6). In this p atient population, a DT of the early wave of the mitral inflow < 140 ms identifi ed the patients with the highest risk of cardiac death. DT is a practical echoca rdiographic parameter for risk stratification of patients with significant left ventricular systolic dysfunction and restrictive filling of the left ventricle.
