Plasma alpha natriuretic peptide in cardiac impairment.

摘要: Regional plasma alpha human atrial natriuretic peptide concentrations were measured, and their relation to intracardiac pressures assessed, in an unselected series of 45 patients undergoing diagnostic cardiac catheterisation. Arteriovenous gradients consistent with its secretion clearance by the liver kidneys. Plasma pulmonary artery, aorta, superior vena cava correlated closely mean right arterial pressures, similar, though weaker, positive relations seen left ventricular end diastolic artery wedge pressures. Concentrations both renin showed significant inverse serum sodium concentrations. are additional objective indicator severity haemodynamic compromise impairment.
