核素心室造影对冠心病心功能的评价

THE EVALUATION OF CARDIAC FUNCTION IN PATIENTS WITH CORONARY HEARTDISEASE BY RADIONUCLIDE VENTRICULOGRAPHY

目的：评价冠心病病人的心脏功能受损及恢复情况。方法：用核素心室造影的方法测定９０例冠心病病人心脏的收缩功能和舒张功能。结果：心绞痛病人心脏的收缩功能正常，舒张功能异常。心肌梗死病人心脏的早期收缩和舒张功能均受损，后期均有所改善。下壁心肌梗死病人心脏收缩功能完全恢复，舒张功能仍低于正常。前壁心肌梗死病人心脏收缩和舒张功能恢复得均较慢。结论：不同类型的冠心病心功能受到不同程度的损害，心脏舒张功能受损先于收缩功能而其恢复则迟于收缩功能。

Objective:To evaluate the cardiac function in patients with coronary heart disease. Methods: Radionuclide ventriculography was used to measure the systolic and diastolic functions of the heart in 90 patients with coronary heart disease. Results:In the group of patients with angina pectoris the diastolic function was abnormal. In the group of patients with myocardial infarction both systolic and diastolic functions were impaired in the early stage, which were improved thereafter. In the patients with inferior wall infarction the systolic function returned to normal, but the diastolic function remained lower. In patients with anterior wall myocardial infarction, the systolic and diastolic functions of the heart were improved slowly after myocardial infarction. Conclusion:In different kinds of coronary heart disease, the cardiac functions were damaged in different ways, the diastolic function was impaired earlier than the systolic function. But the diastolic function was improved later than the systolic function.
