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
