Explanation [[Explanation::The correct answer is acute pericarditis. Pericarditis refers to the inflammation of the fibroelastic sac surrounding the heart (pericardium). It can be dry, fibrinous or effusive independently from the etiology. Depending on the time of presentation and duration, pericarditis is divided into:
  • Acute (<6 weeks)
  • Subacute (6 weeks to 6 months)
  • Chronic (>6 months)

The clinical suspicion of acute pericarditis is based on a history of the characteristic pleuritic chest pain -- which is sharp, constricting, aggravates on inspiration and on lying supine, and relieved by sitting up and leaning forward. A pericardial friction rub may also be auscultated during cardiac examination.

NSAIDs are the mainstay in the treatment of acute pericarditis and ibuprofen is the most preferred drug.
