[Plasma catecholamine level in diagnostic heart catheterization studies].
Plasma catecholamine levels were obtained during diagnostic heart catheterization from pulmonary artery and aorta before and after injection of contrast medium in 31 patients with coronary heart disease and in 18 normals. The most striking difference between both groups is a significant decline of norepinephrine concentration in aortas after injection of contrast medium in the normals (from 296 +/- 24 [mean +/- SEM] to 225 +/- 21 pg/ml [p less than 0.01]) and no change in patients with coronary heart disease. The cause seems to be rather increased elimination than a decrease of secretion of norepinephrine. Adrenalin shows only partially similar results. Further studies will have to show, what could be the reason for these different reactions of catecholamine level in normals and in patients with coronary heart disease.
