ABSTRACT
<p><b>OBJECTIVE</b>To analyze and assess the impact of clopidogrel given preoperatively in coronary artery bypass grafting (CABG) surgery.</p><p><b>METHODS</b>From January 2005 to January 2007, 440 consecutive patients undergoing CABG surgery were divided into two groups the clopidogrel group (with clopidogrel exposure in 5 days prior to surgery, n = 90) and the control group (without clopidogrel exposure > 5 days prior to surgery, n = 350). Patients undergoing emergency surgery because of failed percutaneous transluminal coronary angioplasty and cardiogenic shock, associated valvular surgery, redo-CABG were excluded. Patients who received aspirin and/or heparin treatment before surgery were included.</p><p><b>RESULTS</b>There was no significant difference in two groups regarding age, gender,diabetes mellitus and hypertension. Compared to the control group, patients in clopidogrel group had a higher prevalence of angina class III or IV (66.7% vs. 40.0%, P < 0.01), received more often revascularization within 48 h (41.1% vs. 14.3%, P = 0.02), and had received more frequently stenting (56.7% vs. 13.4%, P < 0.01). Chest tube drainage was significantly increased during the first 24 h following CABG in the clopidogrel group (800 ml vs. 350 ml, P < 0.01). Patients of the clopidogrel group also required more transfusion of packed red blood cells and fresh frozen plasma. Overall re-exploration rate because of bleeding was remarkably higher in the clopidogrel group (4.4% vs. 1.1%, P < 0.01).</p><p><b>CONCLUSIONS</b>Clopidogrel exposure in 5 days or less prior to CABG surgery significantly increases the risk of postoperative bleeding, the need for perioperative transfusion and the incidence of re-exploration. For the elective CABG patient, we suggest that the surgery should to be performed 5 days or more after clopidogrel exposure.</p>
