BACKGROUND Plasma B-type natriuretic peptide (BNP) is a useful biomarker for diagnosis and prognosis of heart failure (HF); however, urine BNP has never been calculated. We sought to compare urinary and plasma BNP levels and to investigate the potential diagnostic and prognostic value of this peptide in HF. METHODS AND RESULTS Urine and plasma BNP levels were measured in 92 HF patients and 30 control subjects. Urinary BNP levels were higher in HF patients than in control subjects (P < .0001… CONTINUE READING
