Carvedilol shows unique effects in murine viral myocarditis; leaves open clinical translation pending human studies.
Does carvedilol improve myocardial histopathological changes and inflammatory markers in a coxsackievirus B3 murine myocarditis model?
Carvedilol provides superior protection in a murine model of viral myocarditis compared to metoprolol, likely due to its antioxidative effects and upregulation of antiinflammatory cytokines.
Li et al. (2008) studied Coxsackievirus B3-induced viral myocarditis. Carvedilol vs. Metoprolol and bunazosin was evaluated on Myocardial histopathological changes, cytokine levels, virus titers, malondialdehyde (MDA), and superoxide dismutase (SOD) contents. Carvedilol attenuated myocardial lesions, reduced virus replication, decreased MDA, and increased SOD in a murine model of viral myocarditis, whereas metoprolol and bunazosin had no significant effects.
