About this trial

This is an exploratory study. A total of 16 patients meeting the inclusion and exclusion criteria and awaiting coronary artery bypass grafting (CABG) surgery will be enrolled. After providing informed consent, participants will be randomized 1:1 under double-blind conditions into two groups:

1. CABG + HiCM-188-loaded chitosan patch group (patch size: 2×4 cm; containing 5 million cells per patch) 2. CABG + blank chitosan patch group (identical in appearance but without HiCM-188 cells).

During CABG surgery, investigators will apply two HiCM-188-loaded chitosan patches onto the epicardial surface over regions of hypokinetic myocardium. The total transplanted cell dose per patient in the treatment group is 1 × 10⁷ . In the control group, eight patients will undergo identical surgical procedures with application of chitosan patches without HiCM-188 cells.

Treatments tested in this trial

  • HiCM-188 Chitosan Patch

    Drug

    Patients receive standard coronary artery bypass grafting (CABG) surgery plus epicardial application of two chitosan patches (each 2×4 cm in size, loaded with 5 million HiCM-188 cells), delivering a total dose of 1 × 10⁷ cardiomyocytes.

  • Blank Chitosan Patch

    Drug

    Patients receive standard CABG surgery plus epicardial application of two identical-appearing chitosan patches containing no HiCM-188 cells
