Pericarditis occurs predominantly in males with severely destructive and nodular RA. The pericardial involvement is usually clinically silent, with the diagnosis made in only 2% of adults and 6% of juveniles with RA. Rarely, pericarditis precedes the onset of RA. Autopsy studies show a pericarditis prevalence of 11-50%.
