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。
Objective: To investigate the characteristics and clinical value of coronary perfusion pressure in patients with dilated cardiomyopathy (DCM) and ischemic cardiomyopathy (ICM). Methods: Coronary perfusion pressure was measured in 40 DCM patients with mild aortic regurgitation and 40 patients with ICM with mild aortic regurgitation using continuous Doppler echocardiography (CWDE). Results: There was no significant difference in cardiac structure, cardiac function and coronary perfusion pressure between the two groups. CONCLUSIONS: There was no significant difference in coronary perfusion pressure between DCM and ICM patients with chronic systolic heart failure.
