Dynamics of parameters of intraventricular filling flows were studied in 83 men (46 older and 37 younger than 60 years) admitted within 12 hours after onset of Q-wave myocardial infarction. Echocardiography was carried out on days 1, 3, 5, and 21 of hospitalization with registration of standard characteristics of left ventricular systolic and diastolic function as well as velocity and time of propagation of intraventricular filling flow. At initial study older patients more often had cardiac failure and ventricular dysfunction. During treatment younger patients had more noticeable decrease of active myocardial relaxation and increase of E/FPV reflecting elevation of intraventricular pressure. Left ventricular remodeling (increases of ventricular diameter and sphericity index) and dilatation were more pronounced in older patients.
