Post-myocardial infarction pericarditis: Dressler syndrome and its clinical implications

Dressler syndrome, a rare complication following myocardial infarction or cardiac surgery, is characterized by a triad of fever, chest pain, and pericardial effusion. Caused by an autoimmune response to cardiac damage, the syndrome can lead to serious complications such as cardiac tamponade and constrictive pericarditis. Diagnosis is made through clinical findings, laboratory tests, and imaging, and treatment involves anti-inflammatory drugs, corticosteroids, and, when necessary, pericardial drainage. Early detection and appropriate management are crucial to prevent complications and improve patient prognosis.
