[Prognostic value of parameters of diastolic left ventricular function and muscular status in elderly patients - survivors of myocardial infarction].
Aim of the study was to assess prognostic value of intraventricular filling flows and parameters of muscular status in patients of elder age group who had survived myocardial infarction. Patients (n=96) aged more than 60 years with Q-wave myocardial infarction were subjected to echocardiographical examination with study of traditional parameters of systolic and diastolic function, as well as velocity (IVFPV) and time of intraventricular filling flow propagation, and calculation of E/IVFPV ratio. Functional state of patients was assessed by means of veloergometry, 6-minute walk test, hand dynamometry, statico-dynamic and static tests. During 2 years of prospective follow-up 29 patients died of cardiovascular pathology. In the group of the deceased parameter E/IVFPV was significantly higher, IVFPV was lower. Significantly lower parameters of tolerance to physical work load, 6-min walk test, strength and endurance of the studied muscle groups were also noted in this group. In the process of regression analysis more strong prognostic parameters of lethal outcome were clinical sighs of heart failure, higher values of E/IVFPV ratio, lowering of muscle strength.
