CIMT was graded 0: normal; 1: <1 mm wall thickening without CP; 2: moderate CP (≥1-≤2.5 mm), MK0683 price 3: CP>2.5 mm). Progression was defined as transition to the next, higher class. Steatosis and fibrosis were assessed by the Fatty Liver Index (FLI, NAFLD present when >60), and by FibroTest (FT). Results.2169 patients were enrolled: 56% males, 52 year-old, BMI 25.4 kg/m2; mean FRS 12±9%, mean CIMT 0.62±0.14 mm; 40.5% had CP and 24% had a FLI60. Pts with NAFLD had higher CIMT (0.64±0.15 vs.0.61 ±0.14 mm, p=0.001), higher prevalence of CP (30% vs.24%, p=0.005) and higher

FRS (17±9% vs.10±8%, p<0.001). FLI was associated with baseline CIMT (p=0.002) and FLI≥60 with CP at baseline (OR=1.27, p=0.04), both independent of age, sex, smoking, diabetes and hypertension. The median f/u was 8 yrs, 6.4 yrs in NAFLD pts and 8.5 yrs in non-NAFLD pts (p<0.001). During f/u, CIMT Anti-infection Compound Library nmr increased

from 0.62 to 0.65 mm, p<0.001, prevalence of CP increased from 41% to 58%, p<0.001 while 38% of pts developed CP. NAFLD at baseline was associated with the progression and occurrence of CP independent of age, sex or the FRS (HR 1.30 and 1.34, respectively both p<0.01). Among non-NAFLD pts at baseline, those who developed NAFLD during f/u had a larger increase in CIMT than those who stayed NAFLD-free.455 pts were evaluated by FT, they were not different from the 1714 untested pts for age, BMI, CIMT and CP prevalence.2% of these patients had a FT>0.48 compatible with bridging fibrosis. Unexpectedly, bridging fibrosis was associated with the presence of CP at baseline and with progression of CP at f/u (HR 3.83, p<0.01), both independent of FRS and FLI>60. Conclusion: In patients at high CV risk, NAFLD and in particular bridging fibrosis contribute to early atherosclerosis and progression thereof, independent of traditional CV risk factors.

EAT was found increased in patients with metabolic syndrome, of which nonalcoholic fatty liver disease (NAFLD) represents the hepatic manifestation.
