摘      要：Coronary subclavian steal syndrome (CSSS) has been recognized lately as an unusual clinical entity,giving rise to angina but rarely causing an acute coronary syndrome (ACS). The prerequisites for the appearance of CSSS are both a patent left internal mammary artery (LIMA) graft and severe stenosis of the left subclavian artery (LSA). However,LSA is often overlooked in the diagnostic evaluation of patients with angina,who have underwent coronary artery bypass grafting (CABG). We report an unusual case of non-ST-segment elevation myocardial infarction (NSTEMI) caused by subtotal occlusion of proximal LSA.
