室壁节段性运动异常在冠状动脉疾病中的诊断价值

Clinical value of regional wall motion abnormality in the coronary artery disease

目的:应用超声心动图探讨室壁节段性运动异常与冠状动脉疾病的关系及其临床应用价值。方法:分析200例冠心痛患者(其中心绞痛138例,急性心肌梗死11例,非Q波心肌梗死6例),全部病例行冠状动脉造影示单支或多支病变。超声心动图选用标准左室短轴和长轴观声像图,显示室壁节段性运动异常。结果:200例冠状动脉疾病患者中,室壁节段性运动异常170例,阳性率达85%。其中多支病变患者室壁运动异常节段与病变血管支配的供血区域较一致,前壁心尖段及后下壁一致程度稍低,前侧壁最低。结论:无创性超声心动图提示室壁节段性运动异常对临床诊断冠状动脉疾病提供较可靠依据。

Objective To explore the relation between regional wall motion abnormality and coronary artery disease and the clinical application values of regional wall motion abnormality by echocardiography. Methods Two hundreds patients with coronary heart disease were analyzed, in which there were 138 patients with angina pectoris,11 with acute myocardial infarction, 6 myocardial infarction without Q-wave. All cases were shown single or multiple lesions by coronary arteriography. Using echocardiography,standard short and long axis image of left ventricle were chosen,displaying regional wall motion abnormality. Results Regional wall motion abnormality in 170 cases (85%) with coronary artery disease was displayed,among which abnormal motion segment of left ventricular wall of multiple pathology was in accordance with the area that pathological vessel dominate, apex segment of anterior wall and posterior inferior wall was lower in consistent degree,and anterior lateral wall was the lowest. Conclusion Regional wall motion abnormality in echocardiography provides more reliable basis for diagnosing coronary artery disease.
