Myocardial infarction is one of the major public concerns in both developed and developing countries. Recently, there is growing interest in potential healthcare applications of marine natural products in the field of cardiovascular research. In the present study, we have examined the membrane-stabilizing potential of marine mucopolysaccharide-chitosan in modulating the aberrations of thiol-dependent membrane-bound ATPases activities, mineral status, and cardiac diagnostic markers in isoproterenol-induced myocardial infarction condition in rats. Dietary intake of chitosan significantly (p < 0.05) counteracted the isoproterenol-induced lipid peroxidation and maintained the levels of thiol contents and cardiac biomarkers at concentrations analogous to that of normal controls in the rat myocardium. Chitosan administration also significantly mitigated isoproterenol-induced aberrations in the membrane-bound ATPase activities in the heart tissue and preserved the myocardial mineral status in serum and heart tissue of experimental rats at near normal value. The results of the present study have indicated that the salubrious effect of dietary chitosan supplementation in attenuating the experimentally induced myocardial infarction condition is probably ascribable to its antioxidant defense and membrane-stabilizing properties.
