Background and Methods: Study Design and Definitions The ACUITY Trial randomized 13,819 patients with moderate and high-risk NSTE-ACS to: –heparin/enoxaparin + GPIIb/IIIa inhibitor, –bivalirudin + GPIIb/IIIa inhibitor, or –bivalirudin alone. Major vascular access site complications were defined as: –access site bleeding requiring invasive intervention, or –hematoma >5cm. Major bleeding (non-CABG-related) was defined as: –intracranial, intraocular, or retroperitoneal, –access site with intervention, hematoma >5cm, –hgb drop >3g/dL with source or >4g/dL without source, –reoperation, –transfusion.

Background: REPLACE-2: Predictors of Major Vascular Complications in PCI Background: Major vascular complications (MVC) associated with significant morbidity in PCI. Methods: MVC defined as vascular access site major bleeding or surgical repair. Results: MVC rate 1.9%, less for BIV vs. H+GPI (1.17% vs. 2.61%, unadjusted OR 0.44, p<0.0001). Conclusions: Altering treatment strategy with regard to the 3 modifiable factors may reduce MVC in PCI.

Background and Methods: Vascular Complications in PCI Major vascular assess site complications are associated with significant morbidity in ACS and PCI. We determined the baseline and procedural predictors of major vascular complications in patients with ACS undergoing PCI via the femoral approach. Manoukian SV et al. TCT 2007.

Results: The ACUITY Trial PCI Population (n=7789) Vascular Complications in PCI In patients with ACS undergoing PCI via the femoral approach, independent predictors of MVC include: age ≥75 years, creatinine clearance <60 mL/min, female sex, prior PCI, prior CABG, and use of H+GPI (vs. BIV). Altering treatment strategy with regard to the modifiable factor (use of H+GPI) may reduce the risk of MVC. Manoukian SV et al. TCT 2007.
