atherosclerotic

The word "atherosclerotic" is the adjective for atherosclerosis, the condition where plaque builds up inside the artery walls, progressively hardening and narrowing them. The term comes from the Greek roots: athērós, meaning "gruel," and sklērós/sklerós, meaning "hard." So it broadly refers to the hardening process associated with atherosclerotic plaque in arteries.

"Atherosclerotic" is almost always used to describe anatomy or pathology. You generally wouldn’t say, "He is atherosclerotic." Instead, you would say, "The patient has severely atherosclerotic coronary arteries," meaning the arteries supplying blood to the heart are narrowed and hardened by plaque.

This condition can lead to serious health problems like heart disease, stroke, and peripheral artery disease. Doctors use terms like "atherosclerotic plaque" for the deposits themselves, or diagnose a patient with "atherosclerotic cardiovascular disease" (ASCVD). You may encounter it in health articles and medical writing, but it isn’t everyday language. It is a precise medical descriptor used to signal specific information about artery health—a mostly silent but potentially dangerous process happening inside the body.
