摘要
对68例疑诊为冠心病患者行心肺运动试验和冠状动脉造影，根据心肺功能指标、心电图运动试验的结果分阳性组与阴性组，以冠状动脉造影结果为标准，评估心肺运动试验中心肺功能指标、心电图运动试验对冠心病诊断的预测价值。结果显示，心电图运动试验诊断冠心病的敏感性为51．28％，特异性为68．97％，阳性预测值为68．97％，阴性预测值为51．28％。心肺功能指标中以最大氧脉率比值作为诊断冠心病的一种预测指标，敏感性为51．28％，特异性为75．86％，阳性预测值为74．07％。提示心肺功能指标对冠心病诊断的预测价值与运动试验相当。
Cardiopulmonary exercise test and electrocardiogram exercise test were performed in 68 patients with suspected coronary artery disease, the diagnostic value of two tests was compared with c, oronary angiography results as the gold standard. The results show that the sensitivity, specificity, positive predictive value and negative predictive value of electrocardiogram exercise test for coronary heart disease were 51.28% , 68.97% , 68.97% and 51.28% respectively; those for ratio of 02 pulse peak in cardiopulmonary exercise test were 51.28% , 75.86% , 74.07% and 53.66% respectively. It suggests that the resuhs of cardiopulmonary exercise test may have the same value as electrocardiogram exercise test in diagnosis of coronary artery disease.
