Response of atrial natriuretic factor to surgical pericardial drainage in patients with chronic pericardial effusion.
Previous studies have demonstrated the importance of atrial transmural pressure in the secretion of atrial natriuretic peptide. These studies have been performed in patients with pericardial effusion and hemodynamic compromise. The response of atrial natriuretic peptide to the drainage of chronic pericardial effusion without clinical evidence of tamponade is unknown. We studied 13 patients with chronic abundant pericardial effusion but without hemodynamic compromise. Blood samples for hormonal determinations were drawn before and after surgical pericardiocentesis. Right atrial pressure was measured during the procedure. Drainage induced a significant increase of atrial natriuretic peptide (from 12 +/- 3.9 to 105 +/- 22.8 pmol/l, P < 0.001, mean +/- S.E.M.), correlated with the fall in right atrial pressure (from 7.65 +/- 1.18 to 4.31 +/- 1.46 mmHg, P < 0.05, r = 0.68, P = 0.01). This increase was inversely correlated with the rise of mean blood pressure after surgery (from 84 +/- 2.37 to 100 +/- 5.3 mmHg, P < 0.05, r = 0.65, P < 0.02). Plasma renin activity decreased after drainage (from 8.12 +/- 2.57 to 3.27 +/- 0.65 ng/ml/h, P < 0.05). Surgery induced an increase of plasma levels of aldosterone (from 811 +/- 241 to 1199 +/- 249 pmol/l, P < 0.05), which were reduced after pericardiocentesis (371 +/- 102 pmol/l, P < 0.02). In patients with chronic abundant pericardial effusion, surgical pericardiocentesis induced a significant increase of atrial natriuretic peptide, correlated with a fall in right atrial pressure. The increase of atrial natriuretic peptide was similar than in patients with tamponade, despite a moderate fall in right atrial pressure.(ABSTRACT TRUNCATED AT 250 WORDS) Topics: Adult; Aged; Atrial Function, Right; Atrial Natriuretic Factor; Catecholamines; Drainage; Humans; Middle Aged; Pericardial Effusion; Punctures; Renin-Angiotensin System; Vasopressins | 1994 |
Pericardial tamponade and excessive secretion of antidiuretic hormone.
We have described a case of presumed excessive antidiuretic hormone (ADH) secretion due to pericardial effusion and tamponade. Pericardiotomy and drainage produced dramatic resolution of the antidiuresis. In the setting of pericardial tamponade, increased antidiuretic hormone secretion may be "appropriate" in response to overriding stimuli from the left atrial stretch receptors and carotid sinus baroreceptors.
