I21.1: Acute transmural myocardial infarction of inferior wall

You are having a heart attack.

The heart is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. The coronary arteries can get narrow due to deposits of fat and calcium. Various things favor these deposits. These include smoking, high blood pressure, and other disorders.

When someone has a heart attack, the coronary arteries have become far too narrow or they have closed up completely. As a result, the heart does not get enough oxygen. As a result, the heart muscle gets damaged or dies off.

The heart consists of various layers. The heart consists mainly of muscle tissue. There is a layer of connective tissue on the outside of the heart. There is a thin membrane inside the heart. The coronary arteries are on the outside of the heart and they then run, via small blood vessels, into the muscle layer. In your case, all the layers of your heart have been damaged. The rear side of the heart is affected.

When someone has a heart attack, they get sudden pains in the chest or arm. They may sweat or feel nauseous. The heart may no longer be working properly. One can then have breathing difficulties and be seriously ill.
