Cardioprotective and prognostic effects of remote ischaemic preconditioning in patients undergoing coronary artery bypass surgery: a single-centre randomised, double-blind, controlled trial

Patients undergoing first time CABG using CPB were randomized to remote ischemic preconditioning (left upper arm) or control after induction of anesthetic.  The metric was myocardial injury measured by troponin levels during the first 3 postop days.  Preconditioning resulted in lower troponin levels and in lower operative mortality.
