This randomized, double-blind clinical trial aims to evaluate the impact of photobiomodulation therapy on postoperative outcomes in patients undergoing coronary artery bypass grafting (CABG). The study will compare two techniques for saphenous vein graft harvesting: the conventional technique and the no-touch technique. Participants will be randomly allocated into four groups: conventional harvesting with placebo, conventional harvesting with photobiomodulation, no-touch harvesting with placebo, and no-touch harvesting with photobiomodulation. The primary objective is to evaluate the effects of photobiomodulation on wound healing and postoperative complications related to the saphenous vein harvesting site. Secondary outcomes include clinical outcomes and functional capacity after surgery. The results may contribute to improving postoperative recovery and optimizing surgical strategies in patients undergoing myocardial revascularization.
