Primary Reperfusion Secondary Stenting Trial
Immediate vs. Delayed Stenting After Primary Percutaneous Reperfusion in ST Elevation Myocardial Infarction

The PRIMACY trial seeks to assess whether a strategy of delayed stent implantation combined with adjunctive anticoagulation is superior to immediate stent implantation at improving cardiovascular outcomes in patients with mechanically reperfused ST-elevation Myocardial Infarction (STEMI). The investigators hypothesize that delayed stent implantation combined with systemic anticoagulation and maximal antiplatelet therapy will reduce the combined occurrence of cardiac death, non-fatal myocardial infarction, congestive heart failure, and target vessel revascularization at 90 days.

Inclusion Criteria:

  1. Age between 18 and 80 years;
  2. STEMI, presenting within 12 hours of symptoms onset, and persisting for more than 20 minutes;
  3. ECG that fulfills any of the following criteria: ≥ 2 mm ST elevation in two anterior or lateral leads; or ≥ 1 mm ST elevation in two inferior leads; or new left bundle branch block (LBBB) with at least 1 mm concordant ST elevation;
  4. Infarct-related artery with TIMI flow 0 or 1 at baseline angiogram;
  5. Successful reperfusion (TIMI 3 flow), either spontaneously or after wire passage, thrombectomy, small size (≤ 1.5mm) angioplasty catheter, and persisting for more than 10 minutes;
  6. Infarct-related artery with a diameter above 2.5 mm.

Exclusion Criteria:

  1. Prior STEMI in the qualifying coronary artery;
  2. Coronary dissection following reperfusion;
  3. STEMI caused by acute stent thrombosis or a venous or arterial bypass graft occlusion;
  4. Significant left main disease, as determined by angiography (≥ 50%) or other imaging technologies;
  5. Cardiac condition requiring emergent or urgent surgical repair;
  6. Failed thrombolysis and rescue PCI;
  7. High risk of bleeding;
  8. Contraindication to either ticagrelor or GpIIb/IIIa inhibitors;
  9. STEMI with Killip III-IV or cardiogenic shock or presenting as sudden death, ventricular fibrillation, or sustained ventricular tachycardia;
  10. Women who are pregnant or breastfeeding;
  11. Creatinine clearance < 20 ml/min;
  12. Other contra-indication to PCI;
  13. Participation to another investigational drug or investigational device study within 30 days prior to randomization (participation to registries is allowed);
  14. Any condition that in the opinion of the investigator would preclude compliance with the study protocol.
