Overview
Dressler's syndrome is a type of pericarditis â inflammation of the sac surrounding the heart (pericardium). Dressler's syndrome is believed to be an immune system response after damage to heart tissue or to the pericardium, from events such as a heart attack, surgery or traumatic injury. Symptoms include chest pain, which may be similar to chest pain experienced during a heart attack.
Dressler's syndrome may also be called postpericardiotomy syndrome, postmyocardial infarction syndrome and post-cardiac injury syndrome.
