Atherosclerosis is the hardening or blockage of arteries, and is a common condition affecting Canadians of all ages. In atherosclerosis, the thick-walls of a patient's blood vessels are blocked which may prevent fresh oxygenated blood from circulating to the body; over time, plagues form within the vessels and build up in the walls causing a thickening and loss of elasticity. If this condition is left unchecked or untreated, patients will experience pain in the heart muscle (angina) or eventually will experience a heart attack.
