The role of nitric oxide in cardiovascular diseases

Reduced bioavailability of NO is thought to be one of the central factors common to cardiovascular disease, although it is unclear whether this is a cause of, or result of, endothelial dysfunction. Disturbances in NO bioavailability leads to a loss of the cardio protective actions and in some case may even increase disease progression. In this chapter the cellular and biochemical mechanisms leading to reduced NO bioavailability are discussed and evidence for the prevalence of these mechanisms in cardiovascular disease evaluated.
