Association of non-alcoholic fatty liver disease and coronary artery disease
Keywords:Nonalcoholic fatty liver disease, Coronary artery disease, Coronary angiography
Background: Nonalcoholic fatty liver disease (NAFLD), a feature of metabolic syndrome is a highly prevalent condition worldwide. Patients with NAFLD have a higher mortality when compared to general population. Many investigators have shown a close relationship between NAFLD and cardiovascular disease which contributes to the total mortality associated with NAFLD particularly in Western population. This study was therefore conducted to evaluate whether NAFLD independently affects angio-graphically proven coronary artery disease in Asians.
Methods: The severity assessment of fatty liver disease was done by ultrasonography and was graded with increased severity from 0 to 4. Coronary angiography was performed to detect the presence or absence of significant coronary artery disease and modified Gensisni score, which determines the severity of coronary atherosclerotic involvement in individual patients was calculated.
Results: Statistical analysis showed that Fatty liver disease was significantly higher in patients with significant coronary artery disease than in non-significant coronary artery disease group. When analyzed on basis on severity of fatty liver disease, modified Gensini score was significantly higher in group with fatty liver grade 2-3 than in group with fatty liver grade 0 or 1. Logistic regression analysis further showed that severity of fatty liver disease had independent effect on coronary atherosclerotic involvement.
Conclusions: From our current study it can be reasonably said that NAFLD may be an independent risk factor for developing arteriosclerosis. This hypothesis should be verified with larger studies in different population groups.
