[A case report of coronary artery bypass grafting in a patient with Sjögren's syndrome].

There have been very few reports on coronary artery bypass grafting (CABG) during collagen disease. This paper reports a 49-year-old female suffering angina after myocardial infarction who revealed preoperatively findings such as arthralgia, thrombocytopenia and positive anti-nuclear antibody. She underwent CABG and was definitely diagnosed as Sjögren's syndrome after the surgery. The coronary artery lesion in this case was mainly attributed to coronary arteritis due to Sjögren's syndrome because she was comparatively young and no other coronary artery risk factors such as hypertension, hyperlipidemia, thickened intima or angitis had been found by aortic pathology. Moreover, anticardiolipin antibody, which is highly related to the myocardial infarction in juveniles, was positive in this case.
