  Purpose

The investigators previously reported that angioplasty postconditioning reduces infarct size (cardiac enzyme release) in STEMI patients with a fully occluded coronary artery at hospital admission. Animal studies have suggested that the time window for applying brief episodes of ischemia and reperfusion aimed at triggering postconditioning's protection is very narrow, i.e. does not expand beyond 1 minute after reflow. We sought to address whether this window might be larger in humans, i.e. whether STEMI patients might be protected several minutes after undergoing spontaneous reperfusion before admission coronary angiography.

Therefore, STEMI patients (onset of chest pain less than 12 hours) with a TIMI flow grade > 1 were eligible for that study. Angioplasty postconditioning was completed as already published and infarct size was assessed by measuring cardiac enzymes release.

Primary Outcome Measures:
  • Size of the infarct [ Time Frame: Day 5 post reperfusion ] [ Designated as safety issue: Yes ]
    Size of the infarct estimated by magnetic resonance imaging at day 5 post-reperfusion


Secondary Outcome Measures:
  • Contractile functional recovery [ Time Frame: 6 months after reperfusion ] [ Designated as safety issue: Yes ]
    Contractile functional recovery estimated by echocardiography at 6th month versus before discharge.


Estimated Enrollment: 72
Study Start Date: July 2009
Estimated Study Completion Date: August 2012
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Postconditionned
36 postconditionned patients
Procedure: Postconditioning
Postconditioning consists of four cycles of one minute balloon inflation followed by one minute of balloon deflation, with the initial inflation being started within the first minute after reopening of the culprit coronary artery.
Sham Comparator: Conventional intervention
36 control patients with conventional primary percutaneaous intervention (PCI)
Procedure: Percutaneaous intervention
Conventional primary percutaneaous intervention
