Predictors for mortality during follow-up by univariate and multivariate Cox proportional hazard regression analysis.

BMI, body mass index; NYHA class, New York Heart Association functional class; COPD, chronic obstructive pulmonary disease; ACEI, angiotensin-converting enzyme inhibitor; AII-blocker, angiotensin II blocker; LV, left ventricular; LVEF, left ventricular ejection fraction NT-proBNP, N-terminal pro-B-type natriuretic peptide; and miR, micro-RNA.
NT-proBNP levels were transformed by the natural logarithm prior to regression analysis due to a right-skewed distribution.
