Abstract/OtherAbstract:
To investigate the secretion of the plasma levels of atrial natriuretic peptide (ANP) in patients with acute myocardial infarction (AMI), we evaluated the relationship between plasma levels of ANP and pulmonary capillary wedge pressure (PCWP) in 45 consecutive patients during the acute phase of AMI ( approximately 12 h after the attack) (group 1) and compared data with those obtained after 1 mo (group 2). In both groups 1 and 2, plasma ANP levels significantly correlated with PCWP. The slope of the linear regression line between the PCWP and ANP in group 1 was significantly lower, by about one-third, than that in group 2. In addition, we examined changes in ANP levels and left ventricular end-diastolic pressure (LVEDP) over 180 min after AMI induced by injection of microspheres into the left coronary arteries of three dogs. The LVEDP and ANP levels 30 min after AMI were significantly higher than those before; however, despite the persistent high LVEDP during the 180 min after AMI, ANP levels decreased gradually and significantly to 63% of the peak level at 150 min. These findings suggest that the secretion of ANP during the acute phase of myocardial infarction may be insufficient relative to the chronic phase.
