Why the study?
Does the PFA100 in vitro bleeding test predict increased bleeding risk (calculated blood loss) in patients undergoing primary CABG?
Population
146 patients undergoing primary coronary artery bypass graft (CABG)
Design
Cohort
Follow-up
5 hours after heparin neutralization

PFA-100 does not predict bleeding after primary CABG; leaves open utility of platelet function testing in cardiac surgery.
Does the PFA100 in vitro bleeding test predict increased bleeding risk (calculated blood loss) in patients undergoing primary CABG?
The PFA100 in vitro bleeding test does not correlate with calculated blood loss in patients undergoing primary CABG, suggesting it may not be a useful predictor of postoperative bleeding risk in this setting.
