case_images: Electrocardiography showed (A) ST-T elevation (red arrow) in the anterolateral and inferior leads in the municipal hospital. (B) Type III atrioventricular block on admission. (C) Sinus rhythm with Q waves (red arrow) in the anterior and inferior leads on day 7 of hospitalization.

case_images: Electrocardiography showed ST-T elevation in the anterolateral and inferior leads at that time (Figure 1A). Electrocardiography revealed a type III atrioventricular block (Figure 1B). Echocardiography showed improved ventricular wall motion (LVEF 53%), while electrocardiography showed sinus rhythm with Q waves in the anterior and inferior leads (Figure 1C).
case_images: (A) CAG excluded coronary artery stenosis. (B) Chest radiography revealed enlarged cardiac size and a lung infection.

case_images: She was suspected to have acute myocardial infarction, but urgent CAG excluded coronary artery stenosis (Figure 2A). Chest radiography revealed enlarged cardiac silhouette and pulmonary infiltrates (Figure 2B).
case_images: (A) Combined treatment of IABP, VA-ECMO, temporary pacemaker, respirator, CRRT with immunosuppression therapy. Changes in (B) cTnI, (C) NT pro-BNP, (D) lactic acid, (E) ALT and creatinine, (F) LVEF during hospitalization.

case_images: The subsequent days of treatment used a combination of IABP, VA-ECMO, temporary pacemaker, respirator, and CRRT with immunosuppression therapy (Figure 3A). The cardiac injury marker cTnI (Figure 3B), NT pro-BNP (Figure 3C), lactic acid (Figure 3D), ALT, and creatinine (Figure 3E) gradually decreased. Echocardiography indicated a progressively improved LVEF (Figure 3F).
case_images: CMR examination showed (A) cardiomyocyte necrosis, diffuse edema, ventricular wall thinning (red arrow), and reduced movement in the left ventricle on day 10 of hospitalization, and (B) slight ventricular septal fibrosis and inflammatory edema at 1 year.

case_images: A CMR examination performed on day 10 revealed cardiomyocyte necrosis, diffuse edema, ventricular wall thinning, and decreased contractility of left ventricle (Figure 4A). Nevertheless, a CMR examination revealed slight ventricular septal fibrosis and inflammatory edema at 1 year (Figure 4B).
