HERMOSILLA M, Karina; PIVCEVIC C, Daniela; ALEGRIA B, Julia  y  SILVA F, Claudio. Correlation between coronary calcium score, hepatic steatosis and metabolic syndrome. Rev. chil. radiol. [online]. 2013, vol.19, n.2, pp.64-68. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082013000200005.

Objectives. To demonstrate the correlation between the presence or absence of established coronary disease (as measured by the Agatston index) and hepatic steatosis visualized in liver segments when calculating calcium score. Material and Methods. Retrospective study that included229 patients with risk factors for coronary disease who underwent multislice computed tomography of coronary arteries or calcium score. We evaluated the presence of atherosclerotic disease in coronary arteries and thoracic aorta and liver attenuation in visualized liver segments. Statistical analysis included linear regression models, association studies of multiple variables and CARTmodel. Results. 229 patients, 78% male, average age 56 years. It values statistically significant association was found between higher levels of calcium score and lower hepatic attenuation in older patients and males. We were to define two types of patients with high calcium score, a group with hypertension - hepatic steatosis and another groups with hypertension and type 2 diabetes; patients that were only obese did not have higher levels of calcium score. Conclusions. A relationship exists between calcified atheromatosis disease and hepatics steatosis. Patients with hepatics steatosis as part of a metabolic syndrome are at increased risk of atherosclerosis. It may be useful to incorporate the assessment of hepatics steatosis in cardiovascular risk stratification.
