Atherosclerosis develops faster as you age. The lesions may even contain living white blood cells. Not being active (sedentary lifestyle) Once the inner wall of an artery is damaged, fatty deposits (plaque) made of cholesterol and other cellular waste products tend to collect at the site of injury. The death rate from coronary artery disease (CAD) has declined considerably over the last three decades. Atherosclerosis, otherwise known as hardening of the arteries, clogged arteries, or blocked arteries, is a buildup of plaque in the blood vessels. Causes. The reported incidence rates in avian species range widely from 1.9 to 91.9%. It’s more common in people over 65 and those with a family history of heart or circulatory diseases.
