The epidemiology of non-alcoholic fatty liver disease and its connection with cardiovascular disease: role of endothelial dysfunction.

The non-alcoholic fatty liver disease is considered a predominant hepatopathy worldwide and a component of metabolic syndrome. It represents a risk factor for the development of cardiovascular diseases, independently of the presence of diabetes mellitus, hypertension and obesity. For this reason, nowadays an epidemiological analysis and a research of the causes that correlate non-alcoholic fatty liver disease and cardiovascular pathologies, are extremely useful. There are important epidemiological variations in relation to various geographical areas, and depending on different population groups, the prevalence of this pathology changes. Epidemiological analysis for non-alcoholic fatty liver disease shows its remarkable relevance and diffusion, especially in Western areas; therefore immediate interventions are necessary for its prevention, diagnosis and therapy. Endothelial dysfunction could be the joining link between non-alcoholic fatty liver diseases and cardiovascular disease risk. Indeed, their correlation should be researched in the alterations that metabolic hepatopathies are able to induce on endothelial function and viceversa. For this reason, the scientific community may research new therapeutic strategies for non-alcoholic fatty liver disease, by intervening on the early stage of the pathology and blocking endothelial dysfunction.
