Brief Summary

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.

Study Arms (2)

IRPC, Remote preconditioning

EXPERIMENTAL

This group will be submitted to ischemic preconditioning

Procedure: IRPC, Remote preconditioning

Control

PLACEBO COMPARATOR

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.

Interventions

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.

IRPC, Remote preconditioning
