SNF indicates skilled nursing facility; CVA/TIA, cerebrovascular accident/transient ischemic attack; LVEF, left ventricular ejection fraction; ICD, implantable cardioverter-defibrillator; CABG/PCI, coronary artery bypass graft surgery/percutaneous coronary intervention; BUN, blood urea nitrogen; COPD, chronic obstructive pulmonary disease; and CAD, coronary artery disease.

Full model of all patient covariates considered. n=14 599 (excludes 860 patients with all laboratory data missing).
