Heart Catheterization
Conditions
Brief summary
To assess whether two doses of dabigatran etexilate (110 mg twice daily (b.i.d) and 150 mg twice daily (b.i.d)) as compared to unfractionated heparin (UFH), both in addition to a standard dual antiplatelet regimen, provide sufficient anticoagulation in the setting of elective percutaneous coronary intervention (PCI).
Interventions
comparison of different dabigatran dosages with unfractionated heparin
comparison of different dabigatran dosages with unfractionated heparin
