[Radionuclide ventriculography in the diagnosis of dilated cardiomyopathy].
Assessment of myocardial contractility function and its diastolic features (according to the results of radionuclide ventriculography with 99mTc-pertechnetate) in patients with dilatory cardiomyopathy (DCMP) revealed a significant decrease in the total ejection fraction, regional ejection fractions, cardiomegaly (an increase in the end-diastolic volume combined with an increase in end-systolic volume and a decrease in the stroke volume) and a decrease in ejection rate indices. Differential criteria for the diagnosis of DCMP and CHD were a greater degree of cardiodynamic indices and a diffuse decrease in myocardial regional contractility function in the former and heterogeneity of changes in regional contractility in the latter pathology. The process of diastolic filling in DCMP patients was characterized by a marked decrease in a filling rate at reduced time of its achievement, and in CHD patients by a decrease in a maximum filling rate in combination with increased time of its achievement.
