目的探讨影响平板运动试验结果的各种因素。方法选择我院2005～2006年临床拟诊为冠心病并行平板运动试验(TET)及冠状动脉造影(CAG)的住院患者278例,对TET阳性与CAG诊断进行对比研究。结果假阳性(TET阳性而CAG阴性)32例,其中自主神经功能紊乱11例,高血压病9例,糖尿病6例,其他疾病6例。假阴性(TET阴性而CAG阳性)14例。其中冠状动脉单支病变12例,双支和三支病变各1例。结论TET如能排除自主神经功能紊乱、高血压病、糖尿病等因素的影响,对诊断冠心病有较高的价值,实际诊断过程中应结合冠状动脉造影才能达到准确的诊断结果。
Objective To explore various factors affecting the outcome of treadmill exercise test. Methods A total of 278 hospitalized patients with coronary heart disease complicated with treadmill exercise test (TET) and coronary angiography (CAG) in our hospital from 2005 to 2006 were selected for the comparative study between TET positive and CAG diagnosis. Results Fake positive (TET positive and negative CAG) 32 cases, of which 11 cases of autonomic dysfunction, hypertension in 9 cases, 6 cases of diabetes, 6 cases of other diseases. False negative (TET negative and CAG positive) in 14 cases. One coronary artery disease in 12 cases, double and triple lesions in 1 case. Conclusion If TET can exclude the autonomic nervous dysfunction, hypertension, diabetes and other factors, it has high value in the diagnosis of coronary heart disease. In the actual diagnosis, coronary angiography should be combined to achieve accurate diagnosis.
