平板运动试验与冠状动脉造影的对比研究

Analysis of treadmill exercise test and coronary angiography

目的通过和冠状动脉造影结果的对比,探讨平板运动试验诊断冠心病的敏感性、假阴性率和临床意义。方法 2011年5月至2013年2月期间我院心内科行平板运动试验检查的患者151例,均于2周内住院进一步完善冠状动脉造影检查,严重者同时给予支架植入术治疗。将冠状动脉造影和平板运动试验的结果进行分析。结果 151例患者中,冠状动脉造影阴性29例,单支病变40例,双支病变26例,三支病变18例,心肌桥38例;平板运动试验阳性113例,阴性38例,平板运动试验诊断冠心病的敏感性90.16%,特异性89.66%,假阴性率9.84%,假阳性率10.34%,其中三支病变的敏感性为100%,与单支病变和心肌桥相比差异有显著统计学差异。结论平板运动试验不仅无创、安全、简便、客观、费用低廉,而且对冠心病的诊断也具有高敏感性、高特异性的特点,尤其对冠状动脉三支病变,是冠心病的首选无创筛查手段,值得临床医师进一步推广研究。

Objective To evaluate the clinical significance of treadmill exercise test on the diagnostic value of coronary artery disease. Methods A total of 151 patients who had undergone treadmill exercise test at least 2 weeks before coronary angiography were enrolled in the study, SPSS 14.0 software was used to analysis the outcomes. Results Of all 151 patients who had undergone coronary angiography, triple vessel stenosis were found in 18cases, double vessel stenosis 26 cases, single vessel stenosis 40 cases, the coronary artery were normal in 29 cases. Of all 151 patients, 38 cases were negative on treadmill exercise test, 113 cases were positive. The sensitivity, specificity, false positive rate, false negative rate were 90.16%, 89.66%, 10.34% and 9.84% individully. Conclusion The treadmill exercise test as a noninvasive method has a important diagnostic value in coronary artery disease, deserved to be studied and developed deeply.
