NCT01898546

Brief Summary

Objectives. We will evaluate the effect of ischemic postconditioning (PCON) on microvascular obstruction (MVO) in patients with a first ST-segment elevation myocardial infarction (STEMI) treated with primary angioplasty. Background. PCON appears as a potentially beneficial tool in STEMI. Its impact on MVO is unknown. Methods. In a multicenter study, 132 patients with a first STEMI will be randomized to undergo primary angioplasty followed by PCON or primary angioplasty alone (non-PCON). MVO and infarct size (IS) will be quantified (% of left ventricular mass) in a core laboratory analyzing late enhancement cardiovascular magnetic resonance imaging.

Outcome Measures

Primary Outcomes (1)

  • Microvascular obstruction

    Microvascular obstruction will be visually defined as a lack of contrast uptake in the core of tissue showing late gadolinium enhancement; the extent of microvascular obstruction will be manually defined and expressed as percentage of LV mass

    1 week

Secondary Outcomes (1)

  • Infarct size

    1 week

Study Arms (2)

Primary angioplasty and postconditioning

EXPERIMENTAL

Primary angioplasty followed by postconditioning

Procedure: Primary angioplastyProcedure: Postconditioning

Primary angioplasty

ACTIVE COMPARATOR

Primary angioplasty alone

Procedure: Primary angioplasty

Interventions

Primary angioplasty preceded by 300 mg aspirin plus 600 mg clopidogrel oral load doses. The radial approach and the use of thrombus aspiration catheters will be recommended. Stent will be implanted in all cases. Balloon pre-dilatation or direct stenting will be decided according to lesion characteristics.

Primary angioplastyPrimary angioplasty and postconditioning

1 min after stent deployment, the angioplasty balloon will be re-inflated 4 times during 1 min at low-pressure (4 to 6 atmospheres), each separated by 1 min of reflow.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients of age ≥ 18 years admitted to two university hospitals for a first STEMI within the first 12 h of chest pain onset, with ST-segment elevation of \>0.1 mV in at least 2 contiguous leads and for whom the clinical decision to treat with percutaneous coronary intervention is made.

You may not qualify if:

  • Documented history of previous infarction
  • Primary percutaneous revascularization not attempted
  • Severe clinical or hemodynamic deterioration
  • Left main stem disease
  • Thrombolysis In Myocardial Infarction (TIMI) 2-3
  • Rentrop collateral flow grade ≥1 upon patient arrival
  • Death, re-infarction, cardiac surgery or severe clinical deterioration before CMR study
  • Patients who denied participation in the registry
  • Any contraindications to CMR
