Postcardiac Injury Syndrome (Dressler Syndrome)

Postcardiac Injury Syndrome (Dressler Syndrome) is a condition that affects the heart and the surrounding tissues after injury to the heart, such as a heart attack or heart surgery. It involves inflammation of the pericardium, the thin sac around the heart, which can cause chest pain and difficulty breathing. This syndrome usually develops weeks to months after the initial heart injury. The main health impact is due to the inflammation causing fluid buildup around the heart, which can affect heart function. Patients may experience fever, fatigue, and a feeling of general illness. The condition reflects the body's immune response to heart tissue damage.

Postcardiac Injury Syndrome (Dressler Syndrome) is an autoimmune-mediated pericarditis that occurs after injury to the heart or pericardium, commonly following myocardial infarction, cardiac surgery, or trauma. The core pathology involves an immune response against exposed cardiac antigens, leading to inflammation of the pericardium and sometimes the pleura. It typically presents weeks to months after the inciting event and is characterized by chest pain, pericardial friction rub, and pericardial effusion. The syndrome is significant because it can cause recurrent pericarditis and potentially lead to constrictive pericarditis if untreated. Diagnosis relies on clinical presentation and exclusion of other causes of pericarditis. The syndrome highlights the role of autoimmune mechanisms in post-injury cardiac complications.
