Effect of troponin T decrease rate within 24 h on the prognosis of patients with acute fulminant myocarditis treated with extracorporeal membrane oxygenation / 中华急诊医学杂志

ABSTRACT

Objective:To analyze the effect of troponin T decrease rate on the prognosis of patients with acute fulminant myocarditis (AFM) following extracorporeal membrane oxygenation (ECMO).Methods:AFM patients treated with ECMO from April 2015 to December 2018 in our hospital were enrolled in this study. According to the hospital survival, patients were divided into the survival group and non-survival group. The decrease rate of troponin T within 24, 48 and 72 h were compared in the two groups.Results:A total of 18 patients with a mean age of 31 years were enrolled. Fifteen patients survived and 3 patients died with an in-hospital survival rate of 83.3%. The decrease rate of troponin T within 24 h was higher in the survival group than that in the non-survival group (49.36% vs.-59.57%, P<0.05), while there were no statistical differences in 48 h and 72 h between the two groups (57.17% vs.-35.67%, 65.53% vs. 58.96%; all P>0.05). Conclusions:ECMO is an effective treatment for cardiogenic shock or cardiac arrest caused by AFM. The decrease rate of troponin T within 24 h supported by ECMO is higher in the survival group.
