Opioid receptors and heart resistance to arrhythmogenic factors

Abstract:
We present detailed data on the role of central and peripheral opioid receptors in the regulation of heart resistance to arrhythmogenic factors. Stimulation of peripheral delta2- and kappa1-receptors increases heart resistance to the arrhythmogenic effect of acute ischemia and reperfusion. Activation of peripheral mu- and delta1-opioid receptors improves electrical stability of the heart in animals with postinfarction cardiosclerosis. Possible mechanisms for opioidergic regulation of heart resistance to arrhythmogenic factors are discussed.
