Vascular calcification is a common pathological process in patients with diabetes, chronic kidney disease, and cardiovascular disease, manifested by the deposition of hydroxyapatite on the walls of blood vessels. Hydrogen sulfide is the third gas signal molecule found in mammals after nitric oxide and carbon monoxide, which has anti-inflammatory, antioxidant stress and other effects in the cardiovascular system. In recent years, it has been recognized that hydrogen sulfide has an anti-vascular calcification effect, and supplementation with hydrogen sulfide and its donors can alleviate vascular calcification. In this review, we discussed the various evidence of the protective effect of hydrogen sulfide on vascular calcification, and highlighted the hydrogen sulfide metabolism changes and the potential regulatory mechanisms of hydrogen sulfide on the pathophysiological changes in vascular calcification.
