Table 2. Factors independently associated with short-term mortality in the current cohort of heart failure patients. The logistic regression model was also adjusted by age, sex, chronic kidney disease, New York Heart Association classification, and left ventricular ejection fraction.

Factor	Hazard ratio (95% CI)	P value
COPD	1.76 (1.03-3.02)	0.039
Sinus rhythm	0.56 (0.34-0.92)	0.022
Triple therapy	0.41 (0.23-0.73)	0.003
Nitrates use	3.01 (1.19-7.63)	0.020
Statins use	0.48 (0.28-0.80)	0.005
Anemia	1.85 (1.12-3.04)	0.016
Hyperkalemia	3.09 (1.64-5.83)	0.001
