超声心动图有关指标对冠心病的诊断价值分析

目的:评价超声心动图各项指标对冠心病的诊断价值。方法:选择120例已诊断或疑似冠心病住院病人进行冠状动脉造影术(CAG)及彩色多普勒超声心动图检查。根据CAG结果将其分为冠心病组和正常组,以CAG结果为标准,对比分析两组超声心动图指标:室壁的节段性运动异常、瓣膜钙化、室壁增厚及左室顺应性降低的发生率.及与CAG结果的关系。结果:超声心动图指标心肌的节段性运动异常和瓣膜钙化与CAG结果存在着显著的相关性(P分别<0.01,<0.05).而心室肥厚和左室顺应性下降与CAG结果没有相关性。结论:超声心动图的心肌的节段性运动异常和瓣膜钙化可作为冠心病诊断依据,以提高冠心病诊断的准确性。

Analysis of thc diagnostic value of several indexes of echocardiography in coronary heart disease

Objective:To evaluate the diagnostic values of several indexes of echocardiography in coronary artery disease (CAD). Methods:A total of 120 inpatients diagnosed or suspected CAD were selected for coronary artery an-giography (CAG) and echocardiography. According to the results of CAG, all cases were divided into two groups: CAD group and normal group. Compared the echocardiography indexes:segmental movement disorder of ventricular wall, valvelar calcification, increased thickness of ventricular wall and reduced compliance of left ventricle between two groups to analyze relation between them and the results of CAG. Results: There was marked correlation among segmental movement disorder of ventricular wall, valvelar calcification and results of CAG (P<0. 01. <0. 05, respectively), but there was no correlation among increased thickness of ventricular wall, reduced compliance of left ventricle and results of CAG. Conclusion:Segmental movement disorder of ventricular wall and valvelar calcification may regard as diagnostic criteria of CAD.
