Abstract
Initial studies from Bowman Gray School of Medicine showed that 18 of 30 patients with classic rheumatoid arthritis (RA) had cardiac involvement from their disease. These abnormalities were detected by echocardiography and consisted of mitral valve and/or pericardial abnormalities. All patients were followed for 4 years from the initial workup. Mitral valve abnormalities were seen on followup in 63% of the patients who initially showed this abnormality, while pericardial effusion remained in 20%. Pericardial thickening persisted in 6 of 7 patients. None of the patients developed constrictive pericarditis or heart failure. There was no definite correlation between persistence of these abnormalities and other clinical data, but it was noticed that patients who had persistent pericardial effusion and mitral valve abnormalities showed a higher number of involved joints and a higher erythrocyte sedimentation rate. The cardiac abnormalities described in this study have remained clinically insignificant in this population of RA patients.
