Dressler syndrome is best described as pericarditis that occurs after which event?

Dressler syndrome is an autoimmune pericarditis that follows a myocardial infarction, usually developing weeks after the heart attack. After myocardial injury, myocardial antigens leak out and trigger an immune response, leading to inflammation of the pericardium (fibrinous pericarditis). This timing after MI—distinct from immediate post-infarct pericarditis—defines Dressler syndrome. The other events listed do not typically trigger this immune-mediated pericarditis, whereas MI does.
