September 29, 2019 updated by: LI ZHAO

Acute Effect of Recombinant Human Brain Natriuretic Peptide in Patients With Pulmonary Hypertension Associated With Acute Exacerbation of Chronic Pulmonary Disease

To evaluate the acute effect of recombinant human brain natriuretic peptide(rhBNP) on pulmonary hypertension of acute exacerbations of chronic pulmonary disease. rhBNP was administered as a continuous infusion for 24 hours , pulmonary artery pressure and other hemodynamic parameters were monitored by Swan- Ganz catheter.

Detailed Description

Pulmonary hypertension (PH) is a descriptive name for abnormally elevated pressures in the pulmonary vasculature, which seriously affects the quality of life and survival of patients. Currently, no effective drugs treatment was used in patients with pulmonary hypertension due to acute exacerbation of lung disease. Recombinant Human Brain Natriuretic Peptide (rhBNP)was approved in 2001 for use in patients with acute heart failure on the basis of studies showing a reduction in pulmonary-capillary wedge pressure(PCWP) and pulmonary arterial pressure (PAP) and improvement cardiac output (CO) . Thus, the study was designed to administer rhBNP as a continuous infusion for 24 hours on pulmonary hypertension of acute exacerbations of chronic pulmonary disease monitoring by Swan- Ganz catheter. Each patient was studied on two occasions (6 hours apart). One occasion the subject received rhBNP 1.5ug/kg IV bolus followed by an infusion of 0.0075ug/kg/min for 24 hours; other occasion the subject received IV placebo bolus followed by a placebo infusion for 24 hours .these were administered in random order in double blind fashion.
