Endothelial dysfunction (EDF) reflects pathophysiologicalchanges in the phenotype and functions of endothelial cells that result fromand/or contribute to a plethora of cardiovascular diseases. We review the roleof hydrogen sulfide (H2S) in the pathogenesis of EDF, one of thefastest advancing research topics. Conventionally treated as an environmentpollutant, H2S is also produced in endothelial cells and participatesin the fine regulation of endothelial integrity and functions. Disturbed H2Sbioavailability has been suggested to be a novel indicator of EDF progress andprognosis. EDF manifests in different forms in multiple pathologies, buttherapeutics aimed at remedying altered H2S bioavailability maybenefit all.
