Dressler syndrome

Dressler syndrome, also referred to as post-myocardial infarction syndrome, is a condition in which there is acute autoimmune pericarditis, generally occurring 2 to 10 days after myocardial infarction. The cause of Dressler syndrome is not entirely understood, but it may be due to the antigens released by the myocardium during an infarction, which form immune complexes with antibodies that cause damage to the pericardium. Dressler syndrome symptoms include fever, pleuritic pain, hypotension, distended neck veins, and muffled heart sounds (Beck's triad) due to pericardial effusion.
