title: B-type natriuretic peptide level in a patient with constrictive pericarditis.
abstract: We report the case of a 35-year-old man with constrictive pericarditis who had a B-type natriuretic peptide (BNP) level of 129 pg/dl despite a left ventricular end diastolic pressure of 35 mmHg. We discuss a possible explanation for the relatively low BNP level given this patient's markedly elevated intracavitary pressures in the setting of constrictive pericarditis.
