The natural antioxidant astaxanthin (AST) demonstrates the cardioprotective effect on cardiac mitochondria in rats subjected to chronic alcohol intoxication. Particularly, AST restored cardiac mitochondrial respiratory activity and Ca2+ capacity of rats exposed to chronic alcohol intoxication; it also had a positive impact on the balance of functionally important processes of mitochondrial fission/fusion, as well as mitophagy. In addition, AST prevented alcohol-induced morphological damage to cardiac tissue. Overall, the results demonstrate that AST promotes normalization of cardiac mitochondrial function, protecting these organelles from degenerative changes caused by alcohol intoxication and improving cardiac energy metabolism. Thus, AST helps to compensate the cardiac mitochondrial damage caused by chronic alcohol intake by restoring their functional activity and stress resistance.
