Pericarditis history often includes which preceding event?

• A. Viral infection
• B. Bacterial infection
• C. Myocardial infarction
• D. Pulmonary embolism

Answer: (A)

Pericarditis is most commonly triggered by a recent viral illness. In many patients, inflammation of the pericardium follows a benign viral infection, such as Coxsackie B or other enteroviruses, often with a preceding upper respiratory or gastrointestinal illness by about one to two weeks. This viral or idiopathic inflammatory pattern is why a history of a recent viral infection is the classic preceding event. Bacterial pericarditis does occur but is much rarer and usually presents with signs of sepsis or purulent drainage, needing urgent treatment. Myocardial infarction can be followed by pericarditis (Dressler syndrome), but that is less common today and not the typical preceding event in most cases. Pulmonary embolism can cause chest pain and pleuritic symptoms but does not ordinarily precede pericarditis. So the best understanding is that a recent viral infection most often precedes pericarditis.
