GRACIA-2 Trial
Primary Optimal Percutaneous Coronary
Intervention versus Facilitated Intervention in STEMI
patients
Presented at
European Society of Cardiology 2003
GRACIA-2 Trial
212 patients with acute ST elevation MI
Presenting within 12 hours of symptom onset
Enrolled at 15 centers in Spain and Portugal
Optimal Primary PCI
 PCI within 3 hours, with or
without abciximab
(n = 108)
Facilitated PCI
 TNK bolus and enoxaparin immediately
 Stent or CABG within 3-12 hours
(n = 104)
Endpoints (follow-up 6 months):


Primary – 1) Infarct size assessed by area under the curve for CKMB
and troponin; 2) myocardial reperfusion by ST resolution at 1, 3, and 6
hours; and 3) LV angio at 6 weeks
Secondary – Death, MI, ischemic driven revascularization at 6 weeks and
6 months; Bleeding events

GRACIA-2 Trial: Results
• Trial designed to determine if facilitated PCI is as safe and
effective as optimal primary PCI alone
• Time from randomization to catheterization:
– 1.08 hours in the primary PCI arm
– 5.89 hours in the facilitated PCI arm
• Infarct size similar in both groups, as was LV ejection
fraction evolution at 6 weeks

GRACIA-2 Trial
• Angiographic data at initial angiography improved with
facilitated PCI
• Complete ST resolution at 6 hours improved with
facilitated PCI
• No increased bleeding with facilitated PCI
• No significant difference in clinical outcomes, although
sample size small (n=212) and underpwoered to show
such a difference
