不同类型心肌病伴慢性收缩性心力衰竭患者冠脉灌注压的临床分析

Clinical analysis of coronary perfusion pressure in patients with different classified cardiomyopathies with chronic congestive heart failure

摘要: 目的:探讨扩张型心肌病（DCM）和缺血性心肌病(ICM)的冠脉灌注压的特点及临床价值。方法：应用连续多普勒超声心动图（CWDE）测量40例DCM伴轻度主动脉瓣反流患者和40例ICM伴轻度主动脉瓣反流患者冠状动脉灌注压。结果：两组在心脏结构、心功能和冠状动脉灌注压等方面均无统计学差异。结论: 伴慢性收缩性心力衰竭的DCM和ICM患者冠状动脉灌注压无显著差异。

Abstract: AIM:To study coronary perfusion in dilated cardiomyopathy (DCM) and ischemic cardiomyopathy (ICM) with chronic systolic heart failure. METHODS: Ultrasound examinations were performed in two groups with mild aortic regurgitation: DCM group (n=40) and ICM group (n=40). Left ventricular end-diastolic dimension (LVEDd), ejection fraction (EF), left ventricular end-diastolic pressure (LVEDP) and coronary perfusion pressure were compared between groups. RESULTS: There were no differences in cardiac structure, function and coronary perfusion pressure between DCM group and ICM group. CONCLUSION: Patients with ischemic cardiomyopathy or nonischemic cardiomyopathy plus systolic heart failure have low coronary perfusion pressure without demonstrating any significant differences between them.
