Answer

Pericarditis in those with rheumatic fever occurs more commonly in lower socioeconomic groups and in children, often accompanying endocarditis and myocarditis, with a worse prognosis. Consider rheumatic fever as an etiology in any child with pericarditis. However, this disease is not a demonstrated cause of constrictive pericarditis.

In adults, pericarditis may not occur with myocardial or valvular involvement, and it is associated with a better prognosis. The pericarditis usually appears 7-10 days after the onset of fever and arthritis. Often, stage 1 electrocardiographic (ECG) findings are absent (see Electrocardiography).
