Abstract:
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.
