as the defects of the adenylate cyclase system in heart failure are attributed to noradrenaline-induced desensitization , it is concluded from the results that , in comparison to the subsensitivity to beta-adrenoceptor agonists in failing human hearts , a decrease in the responsiveness to other receptor-dependent adenylate cyclase stimulators should also occur but only at higher degrees of heart failure .
