[Effect of captopril and lisinopril on adrenergic receptor density and serum norepinephrine and epinephrine in patients with congestive heart disease].

Density of beta-adrenergic receptors in the lymphocytes, alpha 1- and alpha 2-adrenergic receptors in blood platelets, as well as blood serum norepinephrine levels have been assessed in 49 patients with congestive heart failure prior to, and 7 and 14 days of captopril and lisinopril administration. A decrease in beta-, alpha 1-, and alpha 2-adrenergic receptors density, an increase in blood serum norepinephrine, and normal epinephrine levels have been noted in these patients. A 7-day treatment with captopril, and a 14-day treatment with lisinopril have increased adrenergic receptors density, and decreased blood serum norepinephrine levels.
