Congestive heart failure (CHF) is characterized by increased salt and water retention by the kidneys in response to decreased renal blood flow. Increased sympathetic nerve activity is also seen in response to a low cardiac output. Although these compensatory mechanisms are initially important for augmenting cardiac output in a failing ventricle, they ultimately lead to volume overload. B-type natriuretic peptide (BNP), a hormone secreted by the heart in response to increased left ventricular wall tension, is now available as a pharmacolgic agent. BNP interferes with renal mechanisms for salt and water retention and may also inhibit sympathetic nerve activity. We report a patient with New York Heart Association (NYHA) class IV CHF who had dramatic, cyclic clinical improvement due to three repeated courses of intravenous BNP. This patient's
