What is Atherosclerosis?


Atherosclerosis is a chronic and progressive disease in which plaques build up in the walls of arteries. These plaques are formed by cholesterol and other lipids, calcium, and the immune system cells called macrophages.

The word “atherosclerosis” comes from the Greek words “athero,” which means paste, and “sclerosis,” which means hardness. This “hard paste” is called plaque.

“Cardiologists like to describe atherosclerosis as a plumbing problem: Fat and cholesterol-laden gunk gradually builds up within the arteries, they say. If this build-up (plaque) grows thick enough, it eventually plugs an affected pipe.” – in light times

“By 2020, atherosclerosis is expected to be the leading cause of death worldwide.” – MerckManual
