Abstract Aims Patients who survive acute myocardial infarction (AMI) are at risk of being rehospitalized owing to the occurrence of acute decompensated heart failure (HF). However, the clinical characteristics of HF after AMI, especially the frequency of each HF subtype, are unclear. Methods and results We retrospectively studied 1055 patients with AMI. We excluded 257 patients, who were admitted >48 h after the onset of AMI, died during hospitalization or after discharge, and whose echocardiogram data at index hospitalization and follow‐up data were missing. The remaining 798 patients (mean age: 66.5 ± 11.7 years) were investigated for a mean follow‐up period of 4.9 years. All patients underwent emergency coronary angiography. The mean maximum creatine kinase levels were 2898 ± 2627 IU/L, and mean left ventricular ejection fraction (LVEF) was 58.9 ± 10.2%. Eighty‐one patients (10.2%) were rehospitalized because of unexpected worsening of HF. Echocardiography data were available for 74 of the 81 patients during the acute phase of the second hospitalization, of which 30, 20, and 24 patients (41%, 27%, and 32%, respectively) were diagnosed as having HF with preserved LVEF (LVEF ≥ 50%), HF with mid‐range LVEF (40% ≤ LVEF
