  • Model 1: Adjusted for age, sex, alcohol, smoking, diabetes, history of congestive heart failure, history of pulmonary disease, history of liver disease, haemoglobin, ejection fraction below 50% and New York Heart Association functional classification 3 or 4. Model 2: model 1 + quartiles of proANP. Model 3: model 1+ quartiles of NT-proBNP. Model 4: model 1+ quartiles of proANP + quartiles of NT-proBNP.
