Safety and Efficacy of Enoxaparin in Percutaneous Coronary Intervention (PCI) Patients, an International Randomized Evaluation (STEEPLE) - Full Text View

Purpose

The purpose of this study is to evaluate the efficacy and safety of intravenous enoxaparin versus intravenous unfractionated heparin (UFH) in patients undergoing non-emergent PCI, as assessed by measuring the incidence of non-coronary artery bypass graft (CABG) major and minor bleeding.
