The Different Facets of Dyslipidemia and Hypertension in Atherosclerosis.

Atherosclerosis is the narrowing of arteries due to the accumulation of macrophages overloaded with lipids resulting in foam cell formation, and these events occur preferentially at the branching points of arteries which are particularly susceptible to hyperlipidemic stress-induced inflammation and oxidative stress. The different stages of atherogenesis rely on oxidative stress, endothelial dysfunction, and inflammation, and hypertension or dyslipidemia can independently trigger these stages. Dyslipidemia and hypertension are pathological conditions that damage the endothelium, triggering cell proliferation, vascular remodeling, apoptosis, and increased cellular permeability with increased adhesion molecules that bind monocytes and T lymphocytes to create a vicious cocktail of pathophysiological factors.
