Multivariate linear regression results for detecting independent factors on log-transformed plasma NT-proBNP in AF patients.

NT-proBNP = N-terminal proB-type natriuretic peptide; AF = Atrial fibrillation; CHD = Coronary heart disease; LAD = Left atrial diameter; LVEDD = Left ventricular end diastolic diameter; LVEF = Left ventricular ejection fraction; ACEI = Angiotensin-converting enzyme inhibitor; ARB = Angiotensin receptor blocker; CCB = Calcium channel blocker; BMI = body mass index.
