A complete blockage in a coronary artery is called a total coronary occlusion, or if it more than three months old, a chronic total occlusion.
Coronary Artery Disease is the narrowing or blockage of the coronary arteries caused by atherosclerosis.
Atherosclerosis is the buildup of cholesterol, fatty and inflammatory deposits (called plaque) on the inner walls of the arteries that restrict blood flow to the heart. Without adequate blood flow, the heart becomes starved of oxygen and vital nutrients it needs to work properly.
Angina is chest pain or discomfort that occurs when the heart isn’t receiving enough blood. It is a symptom of an underlying heart problem, usually coronary artery disease.
An aortic aneurysm is a bulging section in the aorta, the main artery that carries blood from the heart into the chest and abdomen. An aneurysm that grows too large may burst and cause bleeding.
