Plasma Hydrogen Sulfide Is Positively Associated With Post-operative Survival in Patients Undergoing Surgical Revascularization.

Hydrogen sulfide (HS) is a gaseous signaling molecule and redox factor important for cardiovascular function. Deficiencies in its production or bioavailability are implicated in atherosclerotic disease. However, it is unknown if circulating HS levels differ between vasculopaths and healthy individuals, and if so, whether HS measurements can be used to predict surgical outcomes.
