Essential hypertension is a multifactorial disease. Many experimental studies have elucidated
the role of oxidative stress and atherosclerosis in the pathogenesis of essential hypertension. Apolipoprotein
E is a plasma protein that is found to have antioxidant properties, and it also protects against atherosclerosis.
Interestingly, the biological function of apolipoprotein E is strongly affected by polymorphisms in its gene.
Based on this evidence, our aim was to investigate the association of apolipoprotein E gene polymorphisms with
essential hypertension.
