[Angina Pectoris in a Young Woman with Lupus Erythematosus].

We present a 31-year old woman with a 6-year history of cutaneous lupus erythematosus (CLE) who presented to the emergency room with typical chest pain. ECG and transthoracic echocardiography were normal. Her working diagnosis of pericarditis was made due to systemic progression of her lupus erythematosus (LE). Treatment with NSAIDs was initiated and her immunosuppressive regimen intensified. The patient was discharged after resolution of her symptoms. A week later, the patient was seen at the rheumatology clinic with recurrence and aggravation of her symptoms. She was found to have elevated troponin and cardiac enzymes and therefore underwent cardiac catheterization, revealing three vessel coronary artery disease.  The patient underwent urgent open surgical myocardial revascularization. Despite the immunosuppressive therapy the postoperative course was uneventful.  The risk for coronary artery disease in LE patients is very high. Particularly in young women presenting with chest pain, regardless of typical cardiopulmonary manifestations of LE such as pericarditis and pleurisy, acute coronary syndrome should always be considered.
