Ischemic postconditioning by repetitive cycles of reperfusion and ischemia has been proven both in animal models and in humans. This study aims to investigate the effect of ischemic postconditioning on postoperative hemodynamic function in a standard heart surgery patient population.

Further study details as provided by Oslo University Hospital:

Primary Outcome Measures:
  • Change in cardiac index between the groups during the first postoperative day [ Time Frame: The first postoperative day: measurements at 2, 8 and 18 hrs postoperatively ]
    Cardiac index is measured by a Swan-Ganz catheter inserted preoperatively

Estimated Enrollment: 250
Study Start Date: January 2013
Estimated Primary Completion Date: August 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ischemic postconditioning
Ischemic postconditioning via the cardioplegia line starting with 2 min of reperfusion followed by 2 min of "ischemia" x 3
Procedure: Ischemic postconditioning
No Intervention: Control
Standard operating technique

Detailed Description:

Ischemic postconditioning is studied using cardiopulmonary bypass (CPB) and moderate hypothermia (32-34°C) in a patient population undergoing surgery of the aortic valve (repair/replacement ) or the ascending aorta. Postconditioning is applied by introducing reperfusion/ischemia via the cardioplegia line while the aorta is still cross-clamped thereby preventing the risk of additional neurological complications. All patients > 20 years eligible for aortic or aortic valve surgery and not affected by exclusion criteria, will be included.

The study is carried out as a randomised controlled multicenter study including 5-6 heart surgery centers.


Ages Eligible for Study:   20 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Patients undergoing elective surgery of the ascending aorta or the aortic valve

Exclusion Criteria:

  • Coronary artery disease requiring bypass surgery
  • Tricuspid valve surgery
  • Mitral valve surgery
  • Atrial fibrillation (permanent or paroxysmal with or without concomitant ablation procedure)
  • Patients on per oral or parenteral steroid therapy (inhalational steroids are allowed)
  • Patients with autoimmune diseases
  • "Redo" operations
  • Active endocarditis (ongoing antibiotic therapy)
  • On the discretion of the operating surgeon or anaesthesiologist
