Abbreviations: CI, confidence interval; HR, hazard ratio.
Numbers in table represent no. (95% CI).
a
Discharge aspirin vs. no discharge aspirin, includes adjustment for age and gender.
b
Discharge aspirin vs nondischarge aspirin, includes adjustment for age, gender, diabetes, hypertension, elevated systolic blood pressure, hypercholesterolemia, family history of heart disease, prior aspirin use, prior revascularization, prior myocardial infarction or history of coronary artery disease, ST‐segment depression ≥ 1 mm on electrocardiogram, extracardiac vascular disease, pulmonary edema related to ischemia, and ever smoked.
