Patients’ characteristics and differences between the two treatment groups.

NYHA, New York Heart Association; ACS, acute coronary syndrome; CAD, coronary artery disease; CHF, chronic heart failure; BNP, B-type natriuretic peptide; renal disease, history of chronic renal failure; CPAP, continuous positive airway pressure; PCI, percutaneous coronary intervention ACEI/ARB, angiotensin-converting-enzyme inhibitors/angiotensin II receptor blockers. The systolic blood pressure (SBP), the heart rate (HR), the BNP, the serum creatinine and the left ventricular ejection fraction (LVEF) are presented as the median [IQR]. For categorical variables, the sum of the different categories might be inferior to the sample size because patients’ characteristics were analyzed from complete cases. The p values refer to the comparison of inopressors alone vs. inopressors and inodilators.
