In the general population hepatitis C virus (HCV) infection is commonly correlated with the development of liver complication such as fibrosis, cirrhosis, and hepatocellular carcinoma (HCC) [1,2]. However, even though the exact biological mechanisms are not yet clarified, recent studies have reported an increasing occurrence of extrahepatic complications following chronic HCV infection [3]. In particular, chronic HCV infection appears as an important risk factor for the development of diabetes mellitus [4,5] and an important cause of a variety of otherwise unexplained heart diseases and myocardial injury [6–10].
