Li J, et al. - Researchers examined consecutive patients with acute myocardial infarction admitted at 53 geographically diverse hospitals in China to describe readmission following acute myocardial infarction in China. According to findings, 6.3% of the 3,387 people in the cohort had unplanned 30-day readmission, most of which (77.7%) were attributed to cardiovascular diagnoses. The occurrence of almost half (41.9% of all-cause readmissions; 44.3% of cardiovascular readmissions) was reported within 5 days of discharge. Factors that were related to higher unplanned all-cause readmission were Mini-Global Registry of Acute Coronary Events scores at admission, longer length of stay, and in-hospital recurrent angina. Lower risks of all-cause readmission were reported in relation to revascularization during the index hospitalization. Higher risk of unplanned cardiovascular readmission was observed in relation to factors such as left ventricular ejection fraction <0.4 and in-hospital complication. Lower risk of unplanned cardiovascular readmission was noted in relation to ST-segment–elevation myocardial infarction.
