All major arteries. Arteriosclerosis is generic for hardening of the arteries. Arteriosclerosis of the coronary arteries, also known as cad, is the most widely talked about. Stroke (cerebrovascular accident) is caused by hardening of the brain arteries. Gangrene of legs and feet is caused by hardening of leg arteries also called pad (peripheral artery disease).
Forms or Locations? Atherosclerosis/arteriosclerosis is a body wide process, all arteries. Pathologists have long classified it into 10 different stages correlating with both duration & severity of the disease state. In an advanced lesion, at autopsy, one may be able to find all 10 stages within a single section of an artery. Earliest stage called “fatty streaks”, last stage calcification (always at outer edges).
