脉冲多普勒超声心动图对冠心病舒张功能的研究

A STUDY OF THE DIASTOLIC FUNCTION OF PATIENTS WITH CORONARY HEART DISEASE BY USING PULSED DOPPLER ECHOCARDIOGRAPHY

本研究应用脉冲多普勒超声心动图(PDE)技术,记录20例正常人和37例慢性冠心病伴充血性心力衰竭(CHF)患者的二尖瓣血流频谱。测值分析发现,冠心病伴CHF患者左室舒张早期充盈流速显著降低,晚期充盈流速补偿性升高,提示左室舒张功能障碍普遍存在。

In this study pulsed Doppler eehocardiography (PDE) was used for the recording of mitral blood flow spectra of 20 healthy subjects and 37 coronary heart disease patients with congestive heart failure (CHF). The results indicated that for coronary heart disease patients with CHF, the occurrence of abnormal left vetrieular diastolic function is very common. The main characteristics are the decrease of early filling rate and the compensatory increase of late filling rate.
