title: [Changes in the catecholamine plasma level 3 months after aortocoronary bypass operation].
abstract: Plasma catecholamine levels were obtained during diagnostic heart catheterization from the pulmonary artery and aorta and, similarly, renin levels were determined in the pulmonary artery in 31 patients with coronary heart disease and 18 normal controls. 3 months after aorto-coronary bypass surgery the patients with coronary heart disease underwent repeat heart catheterization and the epinephrine, norepinephrine and renin levels were compared with those obtained before operation. Norepinephrine decreased in the aorta from (means +/- SEM) 475 +/- 57 pg/ml to 360 +/- 38 pg/ml (p less than 0.001) postoperatively (controls 225 +/- 21 pg/ml). Epinephrine decreased from 121 +/- 11 pg/ml to 108 +/- 16 pg/ml (p less than 0.001) postoperatively (controls 84 +/- 9 pg/ml). This shows that postoperative relief from myocardial ischemia is associated with normalization of the preoperatively elevated plasma catecholamine levels).
