不同室壁段心肌梗塞患者左室形态和功能的超声心动图比较

COMPARATIVE STUDY OF LEFT VENTRICULAR STRUCTURE AND FUNCTION IN PATIENT WITH MYOCARDIAL INFARCTION BY DOPPLER ECHOCARDIOGRAPHY

应用多普勒超声心动图对226例不同部位心肌梗塞患者及64例正常人左室形态和功能参数进行对比分析研究.结果表明:心肌梗塞患者左室舒张及收缩末期内径、左室射血分数及短袖缩短率与正常人比较有显著性差异(P<0.01).陈旧心肌梗塞患者的左室扩大更为明显.陈旧前壁心肌梗塞患者的心功能减低更为显著.

The parameters of left ventricular structure and function were studied compared and analysed by doppler echocardiography in 226 patients with myocardial infarction and 64 normal ones for control. The results show: the indexes of LVDd, LVDs, EF and FS were significantly different from normal (P<0.01) . The left ventricular dilation were significantly in old myocardial infarction. The left ventricular function was more decreased in old anterior myocardial infarction.
