[from Jules Levin, NATAP: this study was just published......just below several excerpts are links to a number of studies showing the association between HCV 7 cardiovascular diseases and HCV and also other extra hepatic manifestations & HCV including kidney disease and cancers.]
"clinical studies have shown a higher prevalence of metabolic disorders that are CVD risk factors, specifically type 2 diabetes mellitus (DM) [9], insulin resistance [10], and hepatic steatosis [11], in HCV patients compared to uninfected controls. Moreover, recent data have identified HCV infection as a risk factor for subclinical [12-26] and clinical cardiovascular alterations [27-45]. However, the results of these published studies have been inconsistent, and the overall impact of HCV infection on CVD-related morbidity and mortality is difficult to evaluate.
Considering the availability of new antiviral therapeutic strategies with increased effectiveness and excellent tolerability profiles, a definitive estimate of the impact of HCV infection on CVD-related risk is strongly needed [46]. Therefore, the aim of this meta-analysis was to estimate whether patients infected with HCV, compared to uninfected controls, evidenced increased rates of CVD-related mortality, carotid atherosclerosis, and cerebro-cardiovascular (CCV) events.
This meta-analysis of aggregate data from 22 studies shows that compared to uninfected controls, HCV-infected individuals have increased risks of CVD-related mortality and subclinical carotid atherosclerosis. We observed a slightly significant increase in CCV events among HCV-infected patients, despite the high heterogeneity among studies that was mostly related to the prevalence of DM and hypertension.
Historically, HCV infection has been considered to affect only the liver, via the development of cirrhosis and its complications. HCV infection has also been shown to increase the risk of overall mortality and the occurrence of extrahepatic complications, such as lymphoproliferative disorders and metabolic alterations (insulin resistance and DM). However, recent studies have suggested that HCV-infected patients have an increased risk of developing CVDs [12-45]. To our knowledge, our meta-analysis clearly highlights, for the first time, that HCV infection increases the risk of CVD-related mortality."

Chronic HCV infection was associated with an increased (1.4-fold) mortality from circulatory diseases, which was consistent with other reports in Western countries [3, 20]. We have reported that HCV infection was associated with cerebrovascular death after considering for conventional risk factors. The dose-response relationship between serum HCV RNA level and the risk of cerebrovascular death further strengthened the causal association of HCV infection and atherosclerosis [21]. HCV infection may play as a stimulus for atherothrombosis by triggering a cascade of immune and inflammatory responses, either locally within vascular tissue or systematically through inflammatory mediators [22].

Background & Aims

There have been many studies of the effects of hepatitis C virus (HCV) infection on cardiovascular risk, but these have produced ambiguous results. We performed a meta-analysis of these studies to systematically assess the risk of HCV infection on cardiovascular disease (CVD)-related morbidity and mortality.
We searched PubMed Central, Medline, Embase, and Cochrane Library, as well as reference lists of articles, for studies published through July 2015 that compared the occurrence of CVD between HCV-infected and uninfected subjects, or assessed the prevalence of HCV infection among subjects with CVDs. In total, 22 studies were analyzed. Data on the patient populations and outcomes were extracted from each study by 3 independent observers and combined by a random-effects model.
Compared to uninfected individuals (controls), HCV-infected patients had increased risks of CVD-related mortality (odds ratio [OR], 1.65; 95% confidence interval [CI], 1.07-2.56; P=.02), carotid plaques (OR, 2.27; 95% CI, 1.76-2.94; P<.001), and cerebro-cardiovascular events (OR, 1.30; 95% CI 1.10-1.55; P=.002). Significant heterogeneity was observed in the risk of cerebrocardiovascular disease among individuals with HCV infection. The effect of HCV infection on cerebrocardiovascular disease was stronger in populations with a higher prevalence of diabetes (>10%) or hypertension (>20%) (OR, 1.71; 95% CI, 1.32-2.23; P<.001 for both).
In a meta-analysis of published studies, individuals with HCV infections were found to be at increased risk for CVD-related morbidity and mortality-especially those with diabetes and hypertension.
