Study Summary

INTRODUCTION. Cell-derived microparticles (MP) are released in cell activation, apoptosis and other processes. MP derived from red cells (RMP) are known to be released from stored packed red blood cells (PRBC), and their number increases with storage time. This constitutes one aspect of the storage lesion. Adverse transfusion events are known to increase with time of PRBC storage. The explanation for this is not known. HYPOTHESIS. Based on their findings and those of others, the investigators propose to test the hypothesis that MP in stored PRBC contribute to adverse effects of transfusion. Specifically, MP in stored blood: (1) increase procoagulant activity, expression of pro-inflammatory mediators, immune suppression, and endothelial disturbance; and (2) increase the risk of transfusion and post-operative complications in patients undergoing coronary artery bypass grafting (CABG). AIMS \& PROCEDURES. The aim of this study is to assess the clinical significance of MPs in PRBC-related transfusion complications utilizing washed PRBC. Packed red blood cells (PRBC) will be washed at the blood bank to obtain MP depleted PRBC (PRBC-MP). A total of 500 patients undergoing CABG will be initially randomized to 2 groups: one to receive PRBC-MP, and the other conventional PRBC (PRBC+MP). Using a panel of lab tests/biomarkers selected for high sensitivity the investigators will compare the 2 groups with respect to subclinical physiologic host responses including (i) endothelial disturbances, (ii) inflammatory, and (iii) procoagulant responses. In addition, clinically evident transfusion complications and short term (\<=30 days) surgical complications will be assessed and compared. Patients who are randomized but end up not requiring transfusion at surgery will serve as controls. Laboratory and clinical results will also be evaluated to elucidate which tests are significantly associated with clinically adverse effects. SIGNIFICANCE. This study will shed new light on the bioc
