Heparin+GPI Bivalirudin

Major or minor organ bleeding were reduced to a similar extent in patients treated with bivalirudin alone compared to heparin plus a GPI and were

present with both femoral access (4.1% vs 7.4% respectively. p<0.0001) and radial access (4.9% vs 7.2% respectively. p=0.26).

Bleeding Definitions - 30-day Endpoint

1. Protocol Major (different between REPLACE-2 and ACUITY, HORIZONS)

2. TIMI Major

3. TIMI Minor

4. TIMI Major + Minor

Purpose1. To identify the incidence and source of

bleeding events unrelated to access site among over 17,300 patients undergoing a PCI for a wide variety of clinical diagnoses.

2. Evaluate the impact of antithrombotic therapy (bivalirudin versus heparin + GPIIb/IIIa antagonist) on the occurrence of bleeding unrelated to the access site.

Analysis Population:All PCI patients (ITT) from:

REPLACE-2 N = 6,002ACUITY N = 7,789HORIZONS N = 3,602

Total N = 17,393*

* For primary antithrombotic comparisons the GPIIb/IIIa antagonist + bivalirudin arm (n=2609) of ACUITY was excluded, leaving a total of 14,784 patients.

Sources and Incidence of TIMI Bleeding Among 17,393 PCI Patients 5.3% (n=925) of the study population experienced a TIMI

(Major + Minor) bleeding event.

Access-site only bleeds occurred in

357 (39.6%) of patients.

Bleeding events not

limited to the access site occurred in

568 (60.4%) of patients.

Impact of Randomized Therapy on TIMI Bleeding by Location Exclusive of Access Site

Conclusions1. Two-thirds of PCI patients with a TIMI bleed unrelated

to the access site.

2. Bleeding, irrespective of the source, significantly associated with increased mortality at 1 year.

3. Non-access-related bleeding associated with double the risk of mortality compared to access bleeding.  

4. The use of bivalirudin during a PCI associated with ~40% reduction in non-access site bleeding compared with heparin + a GPIIb/IIIa antagonist.
