Preoperative use of enoxaparin compared with unfractionated heparin increases the incidence of re-exploration for postoperative bleeding after open-heart surgery in patients who present with an acute coronary syndrome: clinical investigation and reports.

Abstract

The preoperative use of enoxaparin compared with UFH in patients presenting with an ACS who undergo open-heart surgery during the same hospitalization is associated with a significantly increased incidence of re-exploration for postoperative bleeding. Further study is needed to understand the mechanism of this phenomenon and to develop appropriate guidelines to address this potentially important issue.
