Abstract:
Objective To investigate the diagnostic value of the combination of exercise electrocardiography test(EET) and coronary artery calcification(CAC) determined by electron beam computed tomography(EBCT) in coronary artery disease.Methods One hundred and thirty-five patients underwent coronary angiography,EET and EBCT.The value of calcium score(CS) and EET in diagnosing coronary artery disease were separately and unitedly evaluated.Results According to calcification score cut points by age and gender,the sensitivity,specificity,positive and negative predictive value of CAC for diagnosing coronary artery disease were 77%,81%,74% and 83%,respectively.The corresponding parameters of EET were 73%,76%,68% and 80%.After combining CAC and EET,the sensitivity and negative predictive value of parallel test were 93% and 92%,and the specificity and positive predictive value were 96% and 91%,respectively.Conclusions Exercise electrocardiography test combined with coronary artery calcification determined by electron beam computed tomography can significantly improve their diagnostic value for coronary artery disease.
