title: Cardiac natriuretic peptide hormones during artificial cardiac pacemaker stimulation and left heart catheterization.
abstract: Brain natriuretic peptide (BNP) is synthesized and released predominantly in the ventricular myocardium whereas atrial natriuretic peptide (ANP) is produced mainly in the atria. This study evaluated whether artificial pacemaker stimulation or left heart catheterization results in specific changes in BNP and ANP plasma levels. Both BNP and ANP responded sensitively to changes in pacemaker stimulation (single-chamber pacemakers; pacing rates of 72 and 92/min) and during the left heart catheterization procedure. However, whereas higher pacing resulted in a more pronounced increase in plasma BNP levels, a stronger ANP release followed catheterization. This incongruous rise in ANP and BNP plasma concentrations points to at least partly independent mechanisms governing the release of BNP and ANP.
