I24.1: Dressler syndrome

You had a heart attack recently. Now your pericardium is inflamed.

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. 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.

Now your pericardium has become inflamed. The pericardium is a layer of connective tissue surrounding the heart. There is some fluid in the pericardium (heart sac). So the heart is able to move inside this lining. The inflammation has not been caused by pathogens. Your own immune system is attacking the cells of the heart. As a result, the tissue has become inflamed.
