What condition is known as Dressler's syndrome?

Dressler's syndrome is recognized as a post-myocardial infarction (MI) condition characterized by inflammation of the pericardium, leading to pericarditis, often accompanied by fever. This syndrome typically emerges weeks to months after a myocardial infarction due to an autoimmune response to the myocardial tissue damaged during the MI. The inflammation causes the classic symptoms of pericarditis, such as chest pain and fever, as the body reacts to what it perceives as foreign material.

The other options do not accurately describe Dressler's syndrome. While post-MI syndromes can indeed include various complications, only the presence of pericarditis and fever distinctly characterizes Dressler's. The condition is not primarily focused on myocardial ischemia or on being a postoperative syndrome; it also does not relate to any post-stroke complications. Therefore, the unique combination of post-MI, pericarditis, and fever defines Dressler's syndrome accurately.
