  Purpose
The aim of this study is to determine whether a closed cell stent design may reduce distal embolization and no reflow during primary percutaneous coronary intervention (PPCI) for acute ST-elevation acute myocardial infarction (STEMI) compared to an open cell stent design. The study population will include all consecutive patients admitted for acute STEMI and treated with PPCI within 12 hours from symptom onset.

Condition Intervention
Acute Myocardial Infarction Primary Percutaneous Coronary Intervention Device: Open cells stent Device: Closed Cells Stent

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: COCHISE Pilot Study: Closed vs Open Cells Stent for High Risk Percutaneous Coronary Interventions in ST Elevation Acute Myocardial Infarction

Primary Outcome Measures:
  • Post procedural angiographic evaluation [ Time Frame: whithin 1 day ]
    The corrected Thrombolysis In Myocardial Infarction (TIMI) frame count at the end of the procedure defined as the number of frames required to opacify angiographic landmarks and normalized for vessel length and a composite end-point including angiographic events such as distal embolization, slow-flow (decrease in flow from TIMI 3 to TIMI 2) or no-reflow (decrease from TIMI 2 or 3 to TIMI 0 or 1) and a binary electrocardiographic criterion of microvascular injury as defined by the presence of persistent (>50% of initial value) ST-segment elevation 30-60 min after procedure


Secondary Outcome Measures:
  • Post stent angiographic results and in hospital MACE [ Time Frame: whithin 7 days ]
    The corrected Thrombolysis In Myocardial Infarction (TIMI) frame count after stent deployment; a composite angiographic end-point including angiographic events such as distal embolization, slow-flow (decrease in flow from TIMI 3 to TIMI 2) or no-reflow (decrease in flow from TIMI 2 or 3 to TIMI 0 or 1) after stent deployment; the infarct size detect by myocardial enzyme release, in hospital major adverse cardac events (MACE)(death, reinfarction, target lesion revascularization)

Criteria

Inclusion Criteria:

  • patients with an age > 18 years with acute ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PPCI) within 12 hours from symptom onset and who agree and provide written informed consent.

Exclusion Criteria:

  • implanted stent with diameter < 2.5 mm
  • cardiogenic shock
  • time from pain onset to PPCI >12 hours
  • previous thrombolytic therapy (rescue PPCI)
  • inability to provide informed consent.
