Crude and Standardized Risk of 30‐Day Readmission After Hospital Discharge, Stratified By MI Type Among Patients Admitted With NSTEMI
| Readmission, % | RD | 95% CIa | RR | 95% CIa | ||
|---|---|---|---|---|---|---|
| Type 2 MI | Type 1 MI | |||||
| Any readmission | ||||||

CI indicates confidence interval; MI, myocardial infarction; NSTEMI, non–ST‐segment–elevation myocardial infarction; RD, risk difference; RR, risk ratio.
CIs determined using the standard deviation estimated from 500 nonparametric bootstrap resamples.
Standardized for patient age, sex, body mass index, hypertension, diabetes mellitus, hyperlipidemia, peripheral vascular disease, chronic kidney disease, smoking status, previous percutaneous coronary intervention, previous coronary artery bypass grafting, and whether aspirin, statins, or beta blockers were prescribed at discharge.
Readmission diagnosis of myocardial infarction, congestive heart failure, cerebrovascular accident, cardiac arrhythmia, cardiac device complication, or structural heart abnormality.
