Background

  • Previous studies have come to differing conclusions

with regards to the role of radial access and bivalirudin in reducing adverse outcomes in patients with ACS

  • It remains unclear whether avoiding access site bleeding

and vascular complications through routine transradial intervention or routine use of bivalirudin improves

  • utcomes in unselected patients with ACS undergoing

invasive management

Summary

  • Radial as compared to femoral access lowered the risk of

NACE, driven by a significant reduction of mortality and bleeding with no difference for myocardial infarction or stent thrombosis. This effect was independent from the anticoagulant used during PCI but expertise in TRI was a treatment modifier.

  • Bivalirudin, when compared to UFH plus provisional

GPI (used in 25% of patients) did not reduce the composite EP of MACE or NACE. however, the use

  • f bivalirudin was associated to reduction of all-

cause and CV death and bleeding including fatal

  • nes. This effect was independent from the access

site used during the procedure.
