Strategies for myocardial protection during open heart surgeries are desired. Several experimental studies have shown beneficial effects of remote ischemic preconditioning (RIPC). The underlying mechanisms are not totally understood. This study intends to evaluate molecular mechanisms involved with RIPC on myocardium of patients underwent open heart surgeries.

Condition Intervention
Coronary Artery Disease
Valvular Heart Disease
Procedure: IRPC, Remote preconditioning

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver)
Primary Purpose: Treatment
Official Title: Evaluation of Remote Preconditioning on Heart Resistance to Ischemia and Reperfusion Injury

Further study details as provided by University of Campinas, Brazil:

  • All cause of mortality [ Time Frame: 180 days ]

Estimated Enrollment: 120
Study Start Date: August 2013
Estimated Study Completion Date: August 2015
Estimated Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: IRPC, Remote preconditioning
This group will be submitted to ischemic preconditioning
Procedure: IRPC, Remote preconditioning
The patients will be submitted to 5 minutes of upper limb compression by cuff followed by 5 minutes of reperfusion. This cycle will be repeated 4 times.
Placebo Comparator: Control
This patients will be submitted to the standard surgery protocol in the institution. The patients will not be submitted to 5 minutes of upper limb compression by cuff followed by 5 minutes of reperfusion.
