Propensity score matching was used to adjust for baseline characteristics yielding 2, 984 well matched patients (1, 492 in each group). The primary endpoint was major non‐coronary artery bypass graft (non‐CABG) related bleeding as defined by a Bleeding Academic Consortium type 3 or 5.

Combined major and minor bleeding was also similar between the two groups (4.3% versus 4.3%, <italic>P</italic> = 1.0). Likewise, no differences were observed between the bivalirudin and UFH groups in terms of in‐hospital death (0.4% versus 0.5%, <italic>P</italic> = 0.592), periprocedural myocardial infarction (1.5% versus 2.0%, <italic>P</italic> = 0.332) and repeat PCI (0.7% versus 0.8%, <italic>P</italic> = 0.669).</p> </sec> <sec id="ccd25911-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Among patients undergoing PCI, there was no significant difference in rate of bleeding between bivalirudin and heparin monotherapy in a real‐world setting. © 2015 Wiley Periodicals, Inc.</p> </sec> </abstract>
