Aim: This study tried to determine the efficacy and safety of low-dose intracoronary unfractionated heparin (UFH) in elective percutaneous coronary intervention (PCI).
Methods: Two-hundred patients who underwent elective PCI of an uncomplicated lesion were included into the study. The patients were assigned to either a control group (70-100 IU/kg intravenous UFH) or a low-dose intracoronary UFH (1,000 IU intracoronary UFH) group.
