ABSTRACT
PURPOSE:
Hepatitis C virus (HCV) infection has been associated with increased risk of cardiovascular disease (CVD). It is unclear whether HCV treatment affects risk of CVD among patients infected with HCV. We assessed the incidence and risk of CVD among insured patients with HCV infection and evaluated if HCV treatment was associated with reduced CVD risk.METHODS:
This retrospective cohort study used MarketScan Commercial and Medicare Supplement databases. Patients newly diagnosed with HCV (vs. patients without HCV) between January 2008 and August 2015 were categorized by treatment (none, insufficient, or minimum effective) based on receipt and duration of anti-HCV treatments. After propensity score matching, time-dependent Cox proportional hazards models were used to compare CVD risk between patients with HCV versus without and between patients with HCV by treatment type and duration.RESULTS:
HCV was associated with 13% increased risk of developing CVD overall (adjusted hazard ratio [aHR] 95% CI 1.26-1.35) and with 13% (aHR 1.07-1,18), 9% (aHR 1.03-1.15), and 32% (aHR 1.24-1.40) significantly increased risks of developing coronary artery disease, cerebrovascular disease, and peripheral vascular disease, respectively. Among patients with HCV, compared with no treatment, receipt of minimum effective treatment was associated with 24% decreased risk of CVD, and receipt of insufficient treatment was associated with 14% decreased risk of CVD.CONCLUSIONS:
Individuals chronically infected with HCV had a higher incidence of CVD. Among patients with HCV, receipt of antiviral treatment for HCV was associated with decreased risk of CVD.Key words
