It is not really the blood vessel that starts a heart attack. Instead, it is the process of narrowing of the arteries that causes it. The heart has 3 main blood vessels that supply different parts of it. If any of these vessels get completely blocked by a blood clot or fat deposition, it could lead to a heart attack. Even if the branches of these vessels get blocked, it could lead to a heart attack.
embolism is the sudden blockage of a blood vessel by an embolus.
a closure or blockage of a blood vessel.
CLOT
Thrombosis is when a blood clot forms inside a blood vessel. This causes a blockage in the circulatory system so that blood cannot pass through freely.
blood clot
embolectomy
A stroke occurs when there is a blocked vessel in the brain. If there is a blockage, no oxygen will pass through, thus a stroke occurs. It's not a heart disease nor is it a disorder.
embolism
Blockage of blood vessels (local or distal), and bleeding (tear of vessel). So: hypertension, cholesterol, cardiac arrhythmias, and trauma.
A blockage in the coronary artery is the most common cause of heart disease. A blockage happens when there is a build up of plaque in the inner lining of the artery. This causes the artery to become narrow or blocked. Since the coronary arteries deliver blood to the heart muscle, any blockage can have serious implications. It reduces the flow of oxygen and nutrients to the heart which may lead to heart attack and possibly death.
Thrombectomy
An angiogram shows disease, narrowing or blockage of a blood vessel.
