We evaluated the predictive value for progression of coronary artery disease （CAD） of leukocyte activation markers in the coronary circulation. Monocyte and neutrophil CDllb, neutrophil CD66b expression and intracellular neutrophil myeloperoxidase （MPO） in the coronary arteries were determined by flow cytometry in patients undergoing coronary angiography. The primary outcome included fatal and nonfatal myocardial infarction or arterial vascular intervention due to unstable angina pectoris. In total 99 subjects who were included, 70 had CAD at inclusion （26 patients had single-vessel disease, 18 patients had two- vessel disease and 26 patients had three-vessel disease）. The median follow-up duration was 2242 days （interquartile range： 2142-2358）. During follow-up, 13 patients （13%） developed progression of CAD. Monoeyte CDllb, neutrophil CDllb and CD66b expression and intraceilular MPO measured in blood obtained from the coronary arteries were not associated with the progression of CAD. These data indicate that coronary monocyte CDllb, neutrophil CDllb and CD66b expression and intracellular MPO do not predict the risk of progression of CAD.展开更多
