[Diastolic function of the left heart ventricle in patients after myocardial infarct].
Altogether 129 patients were investigated 3 months after the onset of myocardial infarction (MI). Left ventricular diastolic function was assessed using a set of parameters of radionuclide ventriculography, including fractions of filling of the first and second thirds of the diastole, increments of volumes in the phases of fast and slow filling, a maximum rate of filling and the time of achieving it. Marked disorders of isovolumetric relaxation (indices of filling of the first third of the diastole) as well as changes of volumetric compliance (a ratio of increments of volumes of filling of the first and second thirds of the diastole) were revealed in the patients. A degree of disorder of left ventricular diastolic function and MI localization showed no correlation, however more noticeable changes were observed in the group of patients with the anterio-apical localization of myocardial lesion as compared to patients with lesions of posterior-lateral localization.
