目的对照平板运动试验与冠状动脉造影结果,探讨平板运动试验可疑阳性的原因。方法101例平板运动试验可疑阳性患者,其中54例在行平板运动试验检查后1～2周内均行冠状动脉造影术,分析这54例患者的平板运动试验和冠状动脉造影结果。结果54例平板运动试验可疑阳性者中有15例冠状动脉造影阳性,39例冠状动脉造影阴性。15例阳性中冠状动脉单支病变12例,双支病变2例,三支病变1例;39例阴性中女性30例,男性9例。结论在平板运动试验可疑阳性而冠状动脉造影阳性病例中男性占50%以上,值得重视;而冠状动脉造影阴性病例女性占80%以上,若能进一步排除各种干扰因素,平板运动试验诊断冠心病的准确性还会有所提高。
Objective To compare the results of treadmill exercise test and coronary angiography to explore the reasons for the suspicious positive of treadmill exercise test. Methods One hundred and eleven patients with suspected positive treadmill exercise test were included in this study. Among them, 54 patients underwent coronary angiography within one to two weeks after treadmill exercise test. The treadmill test and coronary angiography were performed in 54 patients. Results Of the 54 patients with suspected treadmill exercise test, 15 were positive for coronary angiography and 39 were negative for coronary angiography. Among the 15 cases, there were 12 cases with single coronary artery disease, 2 cases with double-vessel disease and 1 case with 3-vessel disease. Thirty cases were negative in 39 cases and 9 cases in males. Conclusions Male patients account for more than 50% of suspected positive cases of treadmill exercise test and coronary angiography. It is worth noting that more than 80% of female patients have negative coronary angiography test. If treadmill exercise test can further diagnose coronary heart disease The accuracy will be improved.
