Its protective effects primarily stem from several mechanisms, including S-sulfhydration of proteins, reduction of cell death, alleviation of mitochondrial damage, improvement of ion channel dysfunction, interaction with nitric oxide, and modulation of angiogenesis. H2S is synthesized by cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE), and 3-mercaptopyruvate sulfurtransferase (3-MST), whose expression is significantly reduced under diabetic conditions, including experimental high-glucose treatment in cells and diabetes mellitus animal models. This review summarizes the protective role of H2S and its donors in these pathological processes, highlights existing research gaps—including challenges in the targeted delivery of H2S donors, limited clinical translation, and incomplete mechanistic understanding—and discusses future directions for developing targeted H2S-based therapeutic strategies.Keywords: H2S, diabetic cardiomyopathy, diabetes-induced endothelial cell damage
