摘要
目的探讨平板运动试验 (TET)诊断冠状动脉粥样硬化性心脏病 (冠心病 )的临床意义。方法选择发作性胸闷、胸痛的患者 3 6例。同期 (1～ 2周内 )进行冠状动脉造影 (CAG)和记录TET心电图变化。冠状动脉狭窄≥ 5 0 %的为冠心病组 ,冠状动脉狭窄 <5 0 %或正常冠状动脉为对照组 ,将两组检查的结果进行对照分析。结果TET检出冠心病的敏感性 95 .45 % (2 1/ 2 2 ) ,特异性 71.42 % (10 / 14) ,准确度 86.11% (3 1/ 3 6)。运动时间、ST段下移幅度及峰心率冠心病组与对照组比较差异显著 (P <0 .0 5 ,P <0 .0 1)。运动试验早期低运动量时出现的心肌缺血提示 2、3支病变。结论利用TET诊断冠心病简便易行、准确高度 。
Objective To investigate the clinical significance of treadmill exercise test(TET)in the diagnosis of coronary heart disease(CHD).Methods 36 patients with onset of chest discomfort were examined by coronary angiography(CAG)and TET in 1 2 weeks.The patients with coronary artery stenosis≥50% were served as CHD group while the patients with coronary artery stenosis <50% or normal coronary artery were served as control group.The results of CAG were compared with that of TET.Results The sensitivity,specificity and accuracy rate of TET in the diagnosis of CHD were 95.45%(21/22),71.42%(10/14)and 86.11%(31/36),respectively.There was a significant difference between the CHD group and control group in the exercise time,the extent of ST segment depression and peak of heart rate(P<0.05,P<0.001).Myocardial ischemia induced at early stage of exercise test and low workload suggested the patients with two or three vessels diseases.Conclusion Treadmill exercise test is a simple and reliable method in the diagnosis of CHD.Some parameters in TET is helpful to predict the severity of CHD.
