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.
对扩张型心肌病（DCMP）患者心肌收缩功能及其舒张特征的评估（根据使用高锝[99mTc]酸盐进行放射性核素心室造影的结果）显示，总射血分数、局部射血分数显著降低，心脏扩大（舒张末期容积增加，同时收缩末期容积增加，每搏量减少）以及射血速率指数降低。DCMP和冠心病诊断的鉴别标准是，前者心脏动力学指标程度更高，心肌局部收缩功能弥漫性降低，而后者病变中局部收缩性变化存在异质性。DCMP患者的舒张期充盈过程的特征是，充盈率在达到该值所需时间缩短时显著降低，而冠心病患者的特征是最大充盈率降低，同时达到该值所需时间增加。
