Abstract:
Objective To systematically evaluate the diagnostic value of treadmill exercise test (TET) compared with dynamic electrocardiography (DCG). Methods Databases including Cochrane library, MEDLINE,EMbase,Google Scholar and CNKI were retrieved to collect randomized clinical trials (RCT) and controlled clinical trials(CCT)focusing on comparison of TET and DCG. After screening according to the inclusion and exclusion criteria,all articles received Jadad quality assessment,and were analyzed using Review Manager Version 5.3 software(The Cochrane Collaboration,Oxford,United Kingdom). Results 9 papers with a total of 667 patients who underwent coronary angiography(CAG),TET and DCG were eventually enrolled. Results of the present Meta?analysis were as below.(1)Sensitivity:9 trials(n = 552)suggested that the sensitivity is 80.62% in TET Group versus 72.64%in DCG Group[RR=1.11,95%CI(1.04~1.18),P=0.002]. The difference was statistically significant.(2)Specificity:7 trails(n=126)indicated that no statistical significance[RR=0.86,95%CI(0.71~1.04),P=0.11]was found in specificity when comparing TET(68/115)and DCG(87/126). Conclusion TET has higher sensitivity but similar specificity in comparison with DCG,and it turns out to be a simple and feasible inspecting method in diagnosing coronary heart disease.
