P interaction<0.001 for smoking and age. STEMI indicates ST‐segment elevation myocardial infarction.
Adjusted for sex, primary payer status, weekend admission, median household income for patient ZIP code, hospital characteristics (bed size, region, location, teaching status), all Elixhauser comorbidities, other clinically relevant comorbidities (known coronary artery disease, carotid artery disease, atrial fibrillation, dementia, dyslipidemia, family history of coronary artery disease, prior myocardial infarction, prior percutaneous coronary intervention, prior coronary bypass surgery), and STEMI location.
