Table 4. Higher and lower discharge heart rates and hazard ratio and 95% confidence interval of post-discharge outcomes.

	All-cause mortality	p value	Heart failure re-admission	p value
Discharge HR (categorical) (higher/lower discharge heart rate)*	1.03 (0.43-2.47)	0.96	0.94 (0.50-1.77)	0.85

Covariates: age, sex, blood pressure, New York Heart Association functional class, left ventricular ejection fraction, brain natriuretic peptide, creatinine, troponin I, rhythm, antihypertensive medications, and history of smoking, alcohol, diabetes, dyslipidemia, and coronary artery disease.

* Heart rates were categorized into higher or lower group based on the median of the discharge heart rate.
