Abstract
Objective To investigate the value of ambulatory electrocardiography(AECG)combined with total ischemic burden(TIB)on the diagnosis of silent myocardial ischemia(SMI)in patients with coronary heart disease(CHD).Methods A total of 95 patients with suspected CHD and SMI were selected.All patients underwent AECG examination,TIB calculation and coronary angiography(CAG)examination.The CAG results were regarded as the gold standard;by using the Kappa consistency test,the consistency between the diagnostic results of AECG,TIB alone or their combination,and the CAG examination results were analyzed in the diagnosis of CHD and SMI.Chi-square test was used to compare the efficiency of AECG,TIB alone and their combination in the diagnosis of CHD and SMI.Results Seventy patients(73.68%)were confirmed with SMI(by CAG examination).In the diagnosis of CHD and SMI,the consistency between the results by AECG combined with TIB and CAG results was both higher than that of AECG or TIB alone(both P<0.01).The sensitivity,specificity,accuracy rate,positive predictive value and negative predictive value of AECG combined with TIB in the diagnosis of CHD and SMI were all significantly higher than those of AECG and TIB alone(all P<0.05).Conclusion The consistency between the results by AECG combined with TIB and CAG examination results in the diagnosis of CHD and SMI proves to be good,and the diagnostic efficiency is higher.关键词
