Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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. Besides, blood samples were stored for the other ancillary studies.

Study Groups

Remote ischemic preconditioning

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

Group Type EXPERIMENTAL

Remote ischemic preconditioning

Intervention Type PROCEDURE

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. RIPC will be performed twice, one at approximately 24 hours before anaesthesia and the other at approximately 1 hour before anaesthesia.

Sham-remote ischemic preconditioning

Transient ischemic ischemia will not actually occur on the upper arm

Group Type SHAM_COMPARATOR

Sham-remote ischemic preconditioning

Intervention Type PROCEDURE

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. Control treatment will be performed twice, one at approximately 24 hours before anaesthesia and the other at approximately 1 hour before anaesthesia.
