Myocardial Infarction

Myocardial infarction is a heart attack caused by a blood clot. If the blood clot stops blood from reaching your heart muscle this is considered myocardial infarction. The treatment for this is to use clot breaking medicine or an emergency procedure to instantly restore the blood flow. The sooner the treatment is conducted the faster the individual can recover and minimize damage to the heart muscle.

The heart muscle is a special muscle referred to as a myocardium. The heart is responsible for pumping blood into the blood vessels which then take the blood to every other part of the body. But just like every other muscle in your body your heart also requires a good supply of blood. The coronary arteries are responsible for taking blood directly to the heart muscle. The main coronary arteries branch directly from the aorta. The main coronary arteries then divide into smaller branches to make sure the blood reaches every other part of the heart muscle.

If you have a myocardial infarction one of your coronary arteries or the small branches will become suddenly blocked. This part of your heart muscle which is supplied by the arteries will lose blood and oxygen. If this is not reversed immediately that heart muscle is at risk of dying. When a part of the heart muscle is damaged it is called infarcted. Therefore the terms myocardial infarction means you have a damaged heart muscle. If your main coronary artery is blocked a larger part of your heart muscle will be affected. But it's a smaller branch of the artery is blocked a smaller part of your heart muscle will be affected. If the heart muscle has died in part because of a myocardial infarction it will be replaced by scar tissue over the course of the next few weeks.

Myocardial infarction is caused by thrombosis or a blood clot. Blood clots generally do not form in your normal arteries but they can form in the lining of your artery. The lining of your artery can become clotted if you have atheroma. This is referred to as a patch of plaque or fat which develops inside the linings of your arteries. Like in this process to water pipes getting stuck with gunk and hair and debris on the inside of the pipe. Plaque along the lining of the artery will gradually form over the course of many years in one or more place within your artery. The plaque has an outer shell which is firm and an inner core which is soft and made up of fatty product. If a crack develops in the outer shell of this plaque it will rupture. This exposes the softer fatty core to your bloodstream. This will trigger a clotting mechanism to form within your blood just stop this buildup. But the buildup intensifies in size and immediately blocks whatever artery it has released into.
