NT-proBNP as a marker of cardiopulmonary status in sickle cell anaemia in Africa.

N-terminal (NT) pro-brain natriuretic peptide (proBNP) > or =160 ng/l has a 78% positive predictive value for pulmonary hypertension and is associated with increased mortality in US sickle cell disease patients, but the importance in sickle cell disease patients in Africa is not known. In a cross-sectional study at Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria, we studied 133 hydroxycarbamide-naïve Nigerian sickle cell anaemia patients aged 18-52 years at steady-state and 65 healthy controls. Twenty-six percent of patients versus 5% of controls had NT-proBNP > or =160 ng/l (P = 0.
