A total of 16 patients meeting the inclusion and exclusion criteria and awaiting coronary artery bypass grafting (CABG) surgery will be enrolled.

CABG + blank chitosan patch group (identical in appearance but without HiCM-188 cells).\n\nDuring CABG surgery, investigators will apply two HiCM-188-loaded chitosan patches onto the epicardial surface over regions of hypokinetic myocardium.
