摘要
目的探讨64排螺旋CT冠状动脉成像与平板运动试验在冠心病诊治中联合应用的价值。方法以选择性冠状动脉造影结果为标准,对比分析64排螺旋CT冠状动脉成像和运动平板试验对114例疑诊冠心病和53例冠心病介入治疗患者诊断的敏感度、特异度、准确度、阳性预测值和阴性预测值。结果64排螺旋CT冠状动脉成像诊断冠心病的敏感度为92.6%,特异度为98.8%,准确度98.4%,阳性预测值为82.5%,阴性预测值为99.5%。64排螺旋CT冠状动脉成像与平板运动试验两者联合应用诊断冠心病的敏感度为90.2%,特异度为99.5%,准确度为99.0%,阳性预测值为91.7%,阴性预测值为99.4%。结论64排螺旋CT冠状动脉成像与平板运动试验均是简便、易行及无创的冠心病诊断方法,两者联合应用可进一步提高诊断冠心病的准确度,并为冠心病介入疗效评价提供依据。
Objective To investigate the value of 64 slice computed tomography and treadmill exercise test in diagnosis of coronary artery disease and to evalute the effect of intervention treatment. Methods Selected coronary arteriography （SCA）,computed tomography angiography （CTA） and treadmill exercise test（TET） were performed in 114 patients with suspected coronary artery disease and 53 patients underwent intervention treatment. The SCA results were served as ＂gold standard＂ to evaluate the diagnostic accuracy of 64-slice computed tomography and treadmill exercise test. Results Compared with SCA,the sensitivity, specificity, accuracy rate,positive and negative predictive values for detecting coronary artery disease were 92.6% ,98.8% ,98.4% ,82.5% and 99.5% in CTA;90.2% ,99.5%, 99.0% ,91.7% and 99.4% in combination detection. Conclusion 64-slice computed tomography and treadmill exercise test are safe,simple and reliable noninvasive methods for diagnosis of coronary artery disease. Combined detection of two methods may improve the diagnostic accuracy of coronary artery disease.
