Animal StudyHighlightedApplication of Molecular Hydrogen in Early Heart Failure Development: Modulation of Microcirculation, Metabolism, Oxidative Stress, and Myocardial StatusMHID-6800574PMID: 414626182025AntioxidantsAnna Vyacheslavovna Deryugina, Darya Andreevna Danilova, Anastasia Vladimirovna PolozovaOxidative stress is a key factor in the development of chronic heart failure (CHF). Molecular hydrogen (H2) exhibits antioxidant properties, yet the mechanisms by which it alleviates hemodynamic disturbances and ischemic myocardial injury in CHF are not fully under- stood. This study examined the effects of a single (40-min) and multiple (40-min daily for 5 days) inhalations of H2 in a rat model o
