目的探讨冠心病的常规超声心动图特征。方法将258例冠心病患者的常规超声心动图资料与冠状动脉造影、左室造影对照分析。结果常规超声心动图诊断符合率为97.7%。主要异常有:左室舒张功能减低184例(71.3%),左室节段性室壁运动异常112例(43.4%),左房扩大92例(35.7%),左室扩大84例(32.6%),二尖瓣反流56例(21.7%)。结论休息状态下大部分冠心病患者并不出现节段性室壁运动异常,左室舒张功能减低是其主要特征。
Objective To investigate the echocardiographic features of coronary heart disease. Methods 258 cases of coronary heart disease in patients with conventional echocardiography data and coronary angiography, left ventricular contrast control analysis. Results The coincidence rate of routine echocardiography was 97.7%. The main abnormalities included left ventricular diastolic function in 184 cases (71.3%), left ventricular segmental wall motion abnormalities in 112 cases (43.4%), left atrium enlargement in 92 cases (35.7%), left ventricular enlargement in 84 cases (32.6% ), Mitral regurgitation in 56 cases (21.7%). Conclusions Most patients with coronary heart disease do not show segmental wall motion abnormalities at rest, and the reduction of left ventricular diastolic function is the main feature.
