cAMP activity and isoproterenol-induced myocardial injury in rats.
Isoproterenol-induced myocardial necrosis (ISO-MN) was obviated by the cardioselective beta-blocker, practolol, suggesting that ISO-MN is caused by specific activation of myocardial beta-adrenergic receptors. Because cAMP is the "second messenger" in such activation, enhanced activity of cAMP should aggravate ISO-MN. Pretreatment of rats with bretylium in various amounts, elicited no ill effects but enhanced the effects of ISO on the cAMP activity and also intensified the ISO-induced structural changes in the myocardium.
