Catastrophic antiphospholipid syndrome with fatal acute course in rheumatoid arthritis.

A 34-year old woman, with a 3 yr history of severe seropositive rheumatoid arthritis (RA) with lupus anticoagulant and anticardiolipin antibodies, developed a massive anterior myocardial infarction and ischemia of the lower extremities, with disseminated intravascular coagulation resulting from extensive tissue damage. Seven days after admission, she died of severe heart failure complicated by ventricular fibrillation. To our knowledge, this is the first documented case of fatal acute antiphospholipid syndrome in RA.
