AMY‐pEF indicates acute myocarditis with preserved ejection fraction; AUC, area under the curve; LAEe, left atrial passive strain; LASRs, left atrial peak positive strain rate; LASRe, left atrial peak early negative strain rate; LVCS, left ventricular circumferential strain; LVLS, left ventricular longitudinal strain; ROC, receiver operating characteristic; and RVLS, right ventricular longitudinal strain.
