Core Tip

Core tip: Hepatitis C virus (HCV) infection represents a risk factor for carotid atherosclerosis, heart failure and ischemic stroke. However, findings from studies addressing coronary artery disease and HCV have yielded conflicting results. Moreover, an excess of cardiovascular mortality among anti-HCV positive subjects has been reported. HCV promotes atherogenesis through direct and indirect mechanisms. Inflammation, cytokines activation, cellular and humoral immunity, metabolic derangement, oxidative stress, liver steatosis and fibrosis have been postulated as potential atherogenic mechanisms. Knowledge of such complex mechanisms may be important for understanding disease progression and promoting novel therapeutic approaches. At present, interferon-based treatment of chronic hepatitis C seems to reduce the risk of stroke as well as non-liver-related mortality.
