男性冠心病患者平板运动试验的意义

目的 探讨平板运动试验诊断男性冠心病的价值.方法 选择拟诊冠心病的男性患者224例,入选病例全部行冠状动脉造影检查,且造影前或造影后1个月行平板运动试验,对比观察以冠状动脉造影直径法确定的冠状动脉狭窄程度和范围与平板运动试验的结果.结果 在224例冠状动脉造影中,阳性171例,阴性53例.其中单支病变87例,双支病变55例,三支病变29例.在平板运动试验中,阳性143例,阴性81例;以冠状动脉造影结果为标准,平板运动试验诊断冠心病的灵敏度为81.3％,阳性预测值为97.2％.同时发现合并高血压或糖尿病患者比单纯冠状动脉病变患者在平板运动试验中ST段下降时间早、持续时间也长,多支病变在平板运动试验中出现ST段下降时间长于单支病变,出现的导联数也多于单支病变.结论 平板运动试验是诊断冠心病的重要手段,并可初步估测冠状动脉狭窄程度.

The significance of treadmill exercise test in male patients with coronary heart disease

Objective To investigate the significance of treadmill exercise test in male patients with coronary heart disease.Methods Two hundred and twenty-four male patients who diagnosed as coronary heart disease by coronary angiography were enrolled in this study,and treadmill exercise test were performed before and 1 month after coronary angiography.The coronary artery stenosis degree and scope were compared between two methods.Results In coronary angiography of 224 patients,the positive was 171 patients and negative was 53 patients.The single stenosis,double stenosis and triple stenosis was 87,55,29 patients.In treadmill exercise test of 224 patients,the positive was 143 patients and negative was 81 patients.The sensibility of treadmill exercise test compared the standard of coronary angiography was 81.3%,positive predictive value was 97.2%.Meanwhile in patients combined with hypertension or diabetic,treadmill exercise test found that the ST segment depression appeared earlier,persistence time longer.The persistence time and the number of down lead in double stenosis and triple stenosis was higher than that in single stenosis.Conclusion Treadmill exercise test is an important method in the diagnosis of coronary artery disease,and can preliminarily estimate the extent of coronary artery stenosis.
