[摘 要] 目的：为了进一步明确诊断冠心病及冠状动脉病变的部位及程度，对冠心病及可疑冠心病患者分别进行运动试验和冠状动脉造影(CAG)，以评估二者之间的相关性。方法：选择运动试验阳性患者100例与CAG情况进行分析比较以便提高临床诊断符合率。结果：有典型的心绞痛，平板试验(TET)阳性与CAG阳性符合率较高；不典型的心绞痛和冠心病危险因素，活动TET与CAG阳性符合率较低。运动试验阳性中，ST段呈水平型或下斜型压低，CAG阳性率高；冠状动脉分支病变，运动试验中出现ST段压低持续时间长，导联数多，两者均多于冠状动脉单支病变。合并高血压或糖尿病患者，运动试验中出现ST段下移的时间早，持续的时间长，与单纯性冠状动脉病变差异有显著的意义。结论：TET阳性患者与冠状动脉病变的关系密切。对冠心病的诊断有较高的敏感性和特异性。[关键词] TET；CAG；冠心病

Abstract：Objective In order to diagnose coronary heart and artery diseases more accurately,and to do exercise test and coronary angiography (CAG) on patients and suspect patients of coronary diseases so as to evaluate the relationship between them.Methods Choose 100 positive patients of exercise test and compare them with the cases of coronary angiography (CAG)so as to raise the rate of conformity in clinical diagnoses.Results With typical angina pectoris,there's a higher conformity rate of positive treadmill exercise test (TET) and positive coronary angiography (CAG).Without typical angina pectoris and dangerous factors of coronary heart diseases,the conformity rate of treadmill exercise test (TET) and positive coronary angiography (CAG) is lower.In positive exercise test,ST segment depresses in horizontal or in slope.The positive rate of coronary angiography (CAG) is high.If there are diseases in some branches of coronary artery,the ST segment depression time becomes long and there are more leads.Both are more than in the case of one branch of coronary artery diseases.Consider patients with high blood pressure or diabetes,the depression time of ST segment in exercise tests comes early and it lasts olng.This is completely different from that of pure coronary artery diseases.Conclusion The positive patients of treadmill exercise test (TET) are closely related to diseases of coronary artery.And it has higher sensitivity and specificity in diagnosing coronary artery diseases. ......
