These patients often present for coronary artery bypass graft surgery (CABG) and are at increased risk for perioperative bleeding.

Using a double-blind design, patients received full-dose aprotinin (n =37) or saline (n =38). Elapsed times between the last dose of clopidogrel and start of the operation were similar between the 2 groups [aprotinin, 58\u00b128 hour (mean\u00b1 SD); control, 54\u00b127 hour;\n            <jats:italic>P<\/jats:italic>\n            =0.86], as were age (aprotinin, 66.4\u00b110 years; control, 68.3\u00b110 years;\n            <jats:italic>P<\/jats:italic>\n            =0.51), number of distal anastomoses (aprotinin, 3.6\u00b11.0; control, 3.7\u00b11.0;\n            <jats:italic>P<\/jats:italic>\n            =0.79), operative times (aprotinin, 192\u00b148 minutes; control, 200\u00b153 minutes;\n            <jats:italic>P<\/jats:italic>\n            =0.55), and lowest intraoperative hemoglobin level (aprotinin, 87\u00b114 g\/L; control, 88\u00b114 g\/L;\n            <jats:italic>P<\/jats:italic>\n            =0.60). Postoperative bleeding was 760\u00b1350 mL in aprotinin-treated patients versus 1200\u00b1570 mL (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.001) in control.

In the aprotinin group, 53% of patients received transfusions, whereas 79% of controls were exposed to blood products (\n            <jats:italic>P<\/jats:italic>\n            =0.02).\n
