Coronary Artery Disease in Systemic Lupus Erythematosus

Abstract

The 10-year survival rate of patients with systemic lupus erythematosus (SLE) currently is more than 85|X%; the greater longevity permits late complications to emerge. Recent studies have shown an increased incidence of coronary artery disease (CAD), frequently in young adults. CAD currently is among the most common causes of death in patients with SLE who survive longer than 5 years. Multiple risk factors, some specific to SLE, are implicated in premature development of CAD. These include coronary artery vasculitis, hypertension and hyperlipidemia, corticosteroid therapy, and antiphospholipid antibodies, which may result in coronary thrombotic events. Therefore, risk factors for CAD should be actively sought as part of routine care of patients with SLE, and appropriate modification strategies, including medications if necessary, should be employed. Noninvasive cardiac tests should be used early in the evaluation of any symptoms consistent with myocardial ischemia, heart failure, or cardiac arrhythmias.
