Pericarditis causing congestive heart failure as an initial manifestation of systemic lupus erythematosus.

Pericarditis is a common complication in systemic lupus erythematosus (SLE) patients, however, that causing congestive heart failure (CHF) is a rare initial manifestation of SLE. We treated a patient whose initial manifestation of SLE was pericardial effusion causing CHF, which improved following prednisolone therapy that led to a dramatic decrease in pericardial effusion and improvement in left ventricular diastolic dysfunction as shown in Doppler echocardiography findings. Further, the plasma brain natriuretic peptide level became normalized.
