title: Acute myocarditis in fulminant systemic sclerosis.
abstract: Myositis and myocarditis have been reported in progressive systemic sclerosis, and these patients have had favorable therapeutic responses to intravenous pulse methylprednisolone. Thus far, premortem biopsy documentation of myocarditis and myocardial fibrosis has not been reported in such patients. We report the case of a patient with subacute congestive heart failure six months after she developed Raynaud's phenomenon. Clinical examination was typical of scleroderma but there was no proximal muscle weakness. She had elevated creatine kinase and MB-creatine kinase and laboratory evidence of hypothyroidism. Echocardiogram demonstrated four-chamber dilatation and severe left ventricular dysfunction. Cardiac catheterization revealed normal epicardial coronary arteries and severely decreased cardiac index. A skin biopsy specimen of the forearm was consistent with diffuse systemic sclerosis, and an endomyocardial biopsy specimen demonstrated mild fibrosis and lymphocytic infiltrate. Her heart failure initially improved with digoxin, furosemide, and enalapril. She also received L-thyroxine and intravenous methylprednisolone. The heart failure progressed over the next six weeks and she died. Patients with scleroderma and new-onset heart failure may have acute myocarditis.
