Values are n (%), except as noted.

CI = confidence interval; NICM = nonischemic cardiomyopathy; OR = odds ratio.

  • Includes all patients with NICM irrespective of whether further etiology was classified.

  • Patients with NICM were the reference group. Model was adjusted for demographics, including age, sex, race/ethnicity, insurance status, body mass index; medical history, including atrial arrhythmia, diabetes, hypertension, smoking, hyperlipidemia, hypertension, lung disease, stroke/transient ischemic attack, peripheral vascular disease, renal insufficiency, depression, valvular heart disease; presentation characteristics, including systolic blood pressure, ejection fraction, heart rate; and hospital characteristics, including region, urban versus rural location, number of beds, academic status.
