Dressler's syndrome refers to pericarditis occurring after which event?

• A. Viral infection
• B. Myocardial infarction
• C. Radiation exposure
• D. Urinalysis abnormalities

Answer: (B)

Dressler's syndrome is an autoimmune-mediated pericarditis that develops after heart muscle damage, classically several weeks following a myocardial infarction. After an MI, cardiac antigens are released and the immune system can mount a response that inflames the pericardium, leading to chest pain that is often pleuritic, sometimes fever, and may be accompanied by a pericardial effusion. This timing and mechanism distinguish it from pericarditis caused by viral infection, radiation, or unrelated issues like urinalysis abnormalities. So, the event associated with Dressler's syndrome is a myocardial infarction.
