Abstract：
:We determined stimulation rates of cardiac adenylate cyclase activity by isoproterenol and impromidine in particulate sarcolemmal membrane preparations from human papillary muscles resected during open heart replacement of mitral and aortic valves. In addition, specific receptor binding studies with [3H]dihydroalprenolol [( 3H]DHA) to cardiac beta-receptors and [3H]tiotidine [( 3H]TIOT) to cardiac H2-receptors were carried out in the same preparations. Compared with the response in patients with pure mitral valve stenosis, the response of cardiac adenylate cyclase activity to isoproterenol showed a marked decrease (-90%) in patients with combined mitral and aortic valve disease, corresponding to the severity of degree of insufficiency at both valves. Similar changes were observed in receptor binding studies with [3H]DHA, in which the reduction of beta-receptor density was of the same order of magnitude. In contrast, stimulation of the enzyme by impromidine and binding capacity of [3H]TIOT to cardiac H2-receptors were found to be unaltered in the same membrane preparations of all 16 patients. We conclude that treatment with H2-agonists may be a new therapeutic approach to congestive heart failure, especially in patients not responding to beta-adrenoceptor stimulation with beta-sympathomimetic drugs.
