After having shown that postconditioning allowed a significant 36% reduction of infarct size as assessed by blood levels of myocardial enzymes in acute myocardial patients, the investigators objective is to assess the effect of postconditioning in acute myocardial infarction (AMI) patients on microvascular obstruction lesions defined by cardiac MRI images.

Condition Intervention
Myocardial Reperfusion Injury
Procedure: postconditioning

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: The POSTCONDITIONING and THE NO REFLOW Phenomenon in Acute Myocardial Infarction

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Extent of the area of microvascular obstruction [ Time Frame: 5 days ]
    Extent of the area of microvascular obstruction defined on post-gadolinium CMR images realized 48-72 hours after admission in each group

Secondary Outcome Measures:
  • Size of the myocardial infarction [ Time Frame: 5 days ]
    Size of the myocardial infarction defined on post-gadolinium CMR images realized 48-72 hours after admission in each group.

Enrollment: 44
Study Start Date: April 2009
Study Completion Date: March 2011
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control
22 controls patients without post conditionment
Experimental: Intervention
22 posconditioned patients
Procedure: postconditioning
Direct postconditioning (brief repeated cycle of 4 occlusion and desocclusion of the initially occluded culprit coronary artery) after primary direct stenting.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients > 18 years old,
