Abstract

Activation of peripheral mu-opioid receptors contributes to an increase in stability of cardiomyocytes to stress damage manifesting with decreased accumulation of Tc-99m pyrophosphate in the heart muscle and contractures of the myocardium. As a principal mechanism of mu-receptor-dependent increase in resistance of the heart to stress damage, modulated influence of opioids on adrenergic pathogenetic links of heart stress damage is considered. In realization of the discovered cardioprotective effect associated with mu-receptor activation, opioidergic limitation of histamine release from mast cells in the myocardium and also mu-receptor-dependent intensification of coronary bloodstream in stressed animals may play a definite role.
