Thirty-Day Readmissions After Myocardial Infarction: Evolving Patterns of Risk Hospital readmissions after myocardial infarction remain a critical marker of care quality and healthcare burden. This large database analysis of over 2.5 million admissions between 2016 and 2020 evaluated trends, predictors, and complications associated with 30-day readmissions. Overall, 8.6% of patients (221,910 cases) were readmitted within 30 days, with a significant decline in readmission risk over time.
Mortality during initial hospitalization also improved (OR 0.92) , reflecting advancements in acute care. However, the patient profile is evolving, with increasing comorbidity burden and a mean age of 66.9 years , both contributing to ongoing risk. Key predictors of readmission included older age (HR 1.01) , higher comorbidity index (HR 1.07), and arrhythmias (HR 1.51), while male sex appeared protective…
