  • Hepatitis C virus (HCV)-infected patients carry a 43% increased risk for cardio-cerebrovascular disease (CCD), driven at least in part by the presence of cirrhosis.

Study design

  • Systematic review and meta-analysis of 27 studies (34 data-sets) involving 297,613 HCV-infected patients and 557,814 control patients.
  • Meta-regression analyses adjusted for demographic variables, antiviral therapy, concomitant medications, and traditional cardiovascular risk factors.

Key results

  • HCV was linked to a significantly increased risk for CCD vs control patients (OR, 1.428; 95% CI, 1.214-1.681; P<.0001).
  • Subgroup analysis confirmed the association between HCV and coronary artery disease (CAD; 20 studies: OR, 1.382; 95% CI, 1.103-1.732; P=.005), and cerebrovascular disease (13 studies: OR, 1.485; 95% CI, 1.079-2.044; P=.015).
  • CCD findings were confirmed by a sensitivity analysis of 21 studies reporting adjusted risk estimates (OR, 1.448; 95% CI, 1.218-1.722; P<.0001).
  • After excluding studies defining CAD as positive angiographic or electrocardiographic evidence, 17 rem...
