atherosclerosis
Pronunciation: ath-er-oh-skleh-ROH-sis
A disease process where fatty deposits (plaques) build up inside artery walls, narrowing blood vessels.
Full Definition
Atherosclerosis is the underlying pathological process in most vascular diseases, characterized by the accumulation of lipids, inflammatory cells, and fibrous tissue within arterial walls. This progressive condition leads to plaque formation that can narrow vessels, restrict blood flow, or rupture to cause acute thrombotic events. The term is fundamental to vascular medicine documentation and appears frequently in patient histories, imaging reports, and treatment plans.
Usage
Usage note: Often confused with arteriosclerosis; atherosclerosis specifically involves lipid deposits, while arteriosclerosis is broader arterial hardening.
