Clinical Trial 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.


Clinical Trial Description

This is a multicentre, randomised, sham-controlled, observer blinded trial. Patients at high clinical risk for cardiovascular events and scheduled to undergo major abdominal surgery will be enrolled. A total of 766 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. ;
