Objective:This study aims to investigate the predictive value of first-time high-sensitivity troponin T(hs-TnT)in patients with acute myocarditis to receive extracorporeal membrane oxygenation(ECMO)support. Methods:A retrospective study was conducted for 98 patients with acute myocarditis. They were divided into ECMO group(n=32) and non-ECMO group(n=66). Baseline data,level of serum hs-TnT and N-terminal pro-B type natriuretic peptide (NT-proBNP) were collected and compared. Results:Total 98 patients were finally enrolled. The levels of serum hs-TnT- and NT-proBNP- in ECMO group[3 580(1 656,8 935)ng/L,10 577(3 701,24 164)pg/mL]were significantly higher than those in non-ECMO group[630(180,1 496)ng/L,565(240,3 736)pg/mL] ,respectively(P < 0.001). Logistic regression analysis showed first-time hs-TnT(OR=1.290,95%CI:1.024~1.626,P=0.031)and NT-proBNP level(OR=1.081,95%CI:1.019~1.146,P=0.009) were independently risk factors of ECMO therapy. Conclusion:The first-time hs-TnT and NT-proBNP level in patients with acute myocarditis could be used to predict whether the patient needs ECMO support.
