Brief summary
Remote ischaemic preconditioning has shown its cardiac protective effect during heart surgery including coronary artery bypass graft surgery, congenital heart disease and aneurysm. However, no data was reported on heart valve disease surgery. Rheumatic heart disease is one of the major heart diseases requiring surgery in China. Thus, the investigators chose heart valve disease as a focus to see whether remote ischaemic preconditioning also has cardiac protective effect during heart valve surgery.
Interventions
Remote ischaemic preconditioning consisted of three 5-min cycles of right upper arm ischaemia, which was induced by an automated cuff -inflator placed on the right upper arm and inflated to 200 mm Hg, with an intervening 5 min of reperfusion during which the cuff was deflated. There was a 5- to 10-min interval between completion of the remote ischaemic preconditioning protocol and initiation of bypass.Control patients had a deflated cuff placed on the right upper arm for 30 min.
