*Adjusted for age, sex, race, education, marital status, home census tract area deprivation index, comorbid conditions (coronary artery disease, arrhythmias, heart failure, peripheral arterial disease, cerebrovascular disease, chronic obstructive pulmonary disease, chronic kidney disease, any cancer, and diabetes), index hospitalization characteristics (length of stay, whether revascularization was performed, and ejection fraction), post-hospitalization cardiac rehabilitation or physical therapy, and physical functioning (TICS, timed up and go, and impairment in activities of daily living).
