Myocarditis as a prognostic indicator in systemic lupus erythematosus.

Lupus myocarditis is a life threatening complication of systemic lupus erythematosus (SLE). A case of left ventricular failure secondary to myocarditis occurring in a patient with SLE is reported. Despite resolution of the cardiac failure with pulsed cyclophosphamide and steroids, she eventually died of non-cardiac complications 18 months later. The literature is also reviewed.
