Study Details

Study Description

Brief Summary

This is a multicentre, parallel-group, randomised, sham-controlled, observer blinded trial, assessing the efficacy of remote ischemic preconditioning on preventing myocardial injury after noncardiac surgery.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Remote ischemic preconditioning
  • Procedure: Sham-remote ischemic preconditioning
N/A

Detailed Description

This is a multicentre, randomised, sham-controlled, observer blinded, phase II trial. Patients at high clinical risk for cardiovascular events and scheduled to undergo major abdominal surgery will be enrolled. A total of 806 patients are randomised (1:1 ratio) to receive RIPC or no RIPC (control) before anaesthesia induction. RIPC will comprise four alternating cycles of cuff inflation for 5 min to 200 mm Hg and deflation for 5 min. In controls, the identical looking cuff will be placed around the arm but not actually inflated for 40 minutes. The primary outcome was myocardial injury after surgery within three days of surgery. The secondary outcomes were peak plasma hs-cTnT and total hs-cTnT release during the first three days after surgery, hs-cTnT above the prognostically important thresholds, length of hospital stay after surgery, and length of stay in the intensive care unit, myocardial infarction, major adverse cardiovascular events, cardiac-related death and all cause death within 30 days, 6 months, 1 year and 2 years after surgery, postoperative morbidity and adverse events within 30 days after surgery.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Remote ischemic preconditioning

Transient ischemic ischemia consisting of 5-minute ischemia followed by 5-minute perfusion will occur on the upper arm

Procedure: Remote ischemic preconditioning
Remote ischemic preconditioning will consist of four cycles of 5-minute inflation of an blood pressure cuff on the upper arm to 200 mmHg followed by 5-minute deflation.

Sham Comparator: Sham-remote ischemic preconditioning

Transient ischemic ischemia will not actually occur on the upper arm

Procedure: Sham-remote ischemic preconditioning
The identical looking cuff will be placed around the upper arm but not actually inflated for 40 minutes. The control device's components and external appearance are identical to that of the RIPC. However, as compared to the RIPC, the blood pressure cuff's line of inflation is disconnected such that the cuff cannot be inflated.
