Brain natriuretic peptide predicts survival in Chagas' disease more effectively than atrial natriuretic peptide

Abstract
Although atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are predictive of left ventricular hypertrophy and dysfunction, they respond differently, for example, to cardiac volume load in fetal circulation or diabetic cardiomyopathy.2 BNP has recently gained increased importance in the clinical diagnosis of cardiovascular diseases, and BNP guided treatment of CHF was found to reduce cardiovascular morbidity.3
