[Radionuclide ventriculography in the evaluation of the diastolic function of the left heart ventricle].
Early changes of left ventricular diastolic function were revealed in patients with various types of coronary heart disease (CHD) on determination of a maximum filling rate (FRmax) and the time of maximum filling rate (T-FRmax) on the basis of radionuclide ventriculography data. A decrease in FRmax and a tendency to an increase in T-FRmax were noted in the group of patients with chronic CHD with normal ejection fraction at rest as well as in the groups of patients with chronic CHD and lowered total ejection fraction at rest and with acute myocardial infarction. Correlation of changes in left ventricular diastolic and systolic functions (the ratio of FRmax/stroke volume) with predominant change of the former was revealed in all the examinees. A high sensitivity of FRmax and T-FRmax in the detection of change of diastolic function in CHD patients was shown.
