摘　　要：目的了解平板运动试验（TET）对高血压合并冠心病患者的诊断价值。方法回顾分析1082例高血压患者的TET结果和TET阳性行冠状动脉造影（CAG）情况，与同期检查的非高血压患者检查结果进行对比分析。结果（1）高血压患者TET阳性率36．7％、可疑阳性率25．0％，均显著高于非高血压患者（20．8％，15．9％，均为P〈0．05）。（2）高血压患者TET阳性或可疑阳性时，CAG阳性率分别为41．0％和28．1％，均显著低于非高血压患者（59．1％，45．1％，均为P〈0．05）。（3）高血压患者TET真阳性时，其CAG冠状动脉重度病变比例显著高于非高血压TET真阳性者（57．3％比31．7％，P〈0．05）。结论高血压患者的TET假阳性率较高，特异性较低，但TET真阳性时，其CAG冠状动脉重度病变比例高。Objective To elucidate the value of treadmill exercise testing （TET） in diagnosis of hypertension （HP） combined with coronary heart disease （CHD）. Methods The results of TET and coronary angiography （CAG） of 1082 hypertensive （HTN） and non-HTN patients were analyzed. Results The positive and doubtful positive percentages were significantly increased in HTN patients than in non-HTN patients （36. 7% vs. 20. 8% , 25.0% vs. 15.9% , both P 〈 0. 05 ） ; （2） The patients with HTN and positive TET demonstrated significantly lower percentages of positive CAG than in non-HTN patients （41.0% vs. 59. 1%, P 〈0. 05） ; The patients with HTN and doubtful positive TET demonstrated significantly lower percentages of positive CAG than in non-HTN patients （28. 1% vs. 45.1%, P 〈 0. 05 ） ; （3） The percentages of severe coronary lesion in CHD patients with HTN was significantly higher than without HTN （ 57. 3% vs. 31.7%, P 〈 0. 05）. Conclusions Patients with HTN have a higher false positive rate and a lower specificity, but HTN patients with CHD have relative severe coronary Lesion.
