ABSTRACT

Introduction: Metabolic síndrome (MS) is a group of abnormalities which favor the development of cardiovascular, hepatic, and degenerative complications; frequently showing a subclinical evolution. Non-alcoholic fatty liver (NAFL), featured by hepatic fat accumulation, is a common condition among patients with MS. It has been associated with cardiovascular risk, suggesting a predictive role.
Material and methods: A cross sectional, comparative, observational study was carried out with the approval of the Institutional Ethics Committee. Patients with MS from the Internal Medicine Department, Hospital General Regional “Lic. Adolfo López Mateos ”, ISSSTE, were included. Patients were not consuming hepatotoxic drugs or alcohol intake higher than 30 grams a day. After informed consent was signed, the following studies were obtained: clinical data, liver function tests, lipids profile and hepatic echography. With this information it was possible to determine the presence of NAFL and cardiovascular risk, assessed by the atherogenic index and risk scale (euro-score). Results. Fifty five patients were studied, mean age 47.4 ± 11.8 years old. The prevalence of NAFL was 36%, a third from which showed high cardiovascular risk. NAFL was not significantly associated with cardiovascular risk (whole relative risk [RR]=0.5, IC95%=0.23-1.26, p=0.1; atherogenic index RR= .82, CI95%=0.48-1.41, p=0.3, and euro-score RR=0.48, IC95%= 0.15-1.51, p=0.1) there was neither significant correlation with other variables (multiple regression associated to body mass index, p=0.44; triacyglycerides, p=0.32).
Conclusion: We found a low association between NAFL and cardiovascular risk, assessed by atherogenic index and clinical scale; nevertheless, the influence of age, sex, body mass index, and dyslipidemia is not ruled out.
