Adjusted for demographic characteristics (age, gender, race, living arrangement, education level), risk factors and medical history (smoking status, hypercholesterolemia, hypertension, peripheral arterial disease, diabetes, chronic renal failure), healthcare access and utilization (avoided medical care due to cost), psychosocial factors (Patient Health Questionnaire score), clinical presentation (systolic blood pressure >140 at presentation, left ventricular systolic function, ST-elevation acute myocardial infarction, GRACE risk score), functional status (SF-12 Physical Component Summary scale, SF-12 Mental Component Summary scale, Seattle Angina Questionnaire scores), and quality of care received (revascularization procedure, patient instructions including weight management and cardiac rehabilitation, aspirin at arrival and discharge, and beta-blockers at discharge).
