ATHEROSCLEROSIS: THE PROCESS OF HARDENING OF THE CORONARY ARTERIES

A HEALTHY CORONARY ARTERY:

A healthy artery is normally smooth-walled. Blood flows through it easily without any turbulence. Healthy coronary arteries provide the heart with sufficient blood both during rest and when the heart's demands are raised e.g., during exercise.

ATHEROSCLEROSIS:

This is the scientific name for the process of hardening of the coronary arteries. The process of atherosclerosis is a universal process of ageing (like the age-related whitening of our hair). It occurs in everyone to some extent with advancing age. Atherosclerosis begins from early childhood by deposition of cholesterol and other fatty substances (called fatty plaques) in the wall of the arteries. This process goes on during an individual's life, slowly in some and faster in others.
