摘要Background Adult Fulminant myocarditis(FM)is the more serious form of acute myocarditis,and extracorpo-real membrane oxygenation(ECMO)is an effective adjunction that helps to maintain circulation while providing adequate treatment.The blood supply of vital organs is guaranteed,which helps patients to survive the acute attack and improves the survival rate of FM.Methods In this study,50 clinical data of adult FM patients received in our hospital from July 2018 to July 2023 were collected for retrospective analysis.According to different treatment methods,they were divided into ECMO group(n=25)and non-ECMO group(n=25).After 14 days of treatment,the level of left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),creatine kinase isoenzymes(CK-MB),cardiac troponin I(cTnI)and brain natri-uretic peptide(BNP),and the incidence of complications were compared between the two groups.Results Before treatment,there was no significant difference in cardiac function between the two groups(P＞0.05).After 14 days of treatment,ECMO group showed greater decline than non-ECMO group in LVESD and LVEDD,and LVEF was higher than that in the non-ECMO group(P＜0.05).The level of CK-MB,cTnl and BNP in ECMO group were lower than those in non-ECMO(P＜0.05).The overall incidence of complications was 8％in the ECMO group,which was lower than 32％in the non-ECMO group(P＜0.05).Conclusions The early efficacy of ECMO treatment in adult patients with FM is considerable,which is conducive to improving the cardiac function of patients and preventing complications.
