Abstract:
Objective To evaluate the value of the combination of troponin and copeptin in the early diagnosis of acute myocardial infarction(AMI) by a meta-analysis.Methods The studies about the application of the combination of troponin and copeptin in the early diagnosis of AMI were searched from Pubmed,CNKI,Wan Fang and VIP databases during their inception and May 2016,and were analyzed by the Meta-DiSc 1.4 software.Results A total of 19 relevant studies were enrolled,including 11 176 patients.95％ CI was calculated with the random effect model.The sensitivity,specificity,positive likelihood ratio,negative likelihood ratio,diagnostic odds ratio(DOR) and the area under curve(AUCROC) of troponin alone and the combination of troponin and copeptin in the early diagnosis of AMI were 77％ (75％-79％) and 92％ (91％-93％),0.85 (0.85-0.86) and 0.60 (0.59-0.61),5.78 (4.01-8.32) and 2.25 (1.98-2.55),0.22(0.18-0.28) and 0.12 (0.09-0.17),32.21 (23.72-43.75) and 20.23 (14.33-28.55),and 0.911 8 and 0.788 8,respectively.Conclusion The combined detection of troponin and copeptin has high sensitivity,which may reduce the rate of missed diagnosis of AMI.However,the detection of troponin alone has high specificity and diagnostic accuracy.
