What causes a coronary occlusion?
If you have too many cholesterol particles in your blood, cholesterol may accumulate on your artery walls. Eventually, deposits called plaques may form. The deposits may narrow — or block — your arteries. These plaques can also burst, causing a blood clot to form.
What happens coronary occlusion?
When one or more of the coronary arteries suddenly becomes completely blocked, a heart attack (injury to the heart muscle) may occur. If the blockage occurs more slowly, the heart muscle may develop small collateral blood vessels (or detours) for other coronary arteries to reroute the blood flow, and angina occurs.
What is the most common cause of coronary occlusion?
The most common cause of CAD is vascular injury with cholesterol plaque buildup in the arteries, known as atherosclerosis. Reduced blood flow occurs when one or more of these arteries becomes partially or completely blocked.
Can a total occlusion be stented?
What is a Coronary Chronic Total Occlusion? Coronary arteries with severe blockages, up to 99%, can often be treated with traditional stenting procedure. Once an artery becomes 100% blocked, it is considered a coronary chronic total occlusion, or CTO.
Is coronary occlusion hereditary?
Coronary artery disease (CAD) has important genetic underpinnings considered equivalent to that of environmental factors. The heritability of CAD has been estimated between 40% and 60%, on the basis of family and twin studies, a method that yields high precision despite potential bias (Vinkhuyzen et al1).
How long can a person live with clogged arteries?
The life expectancy for congestive heart failure depends on the cause of heart failure, its severity, and other underlying medical conditions. In general, about half of all people diagnosed with congestive heart failure will survive five years. About 30% will survive for 10 years.
