Popis: Although coronary artery bypass graft (CABG) surgery is one of the most worldwide commonly performed cardiac surgeries to enhance myocardial perfusion in high-grade myocardial occlusion, it remains a high-risk procedure. Photobiomodulation (PBM) is one of the methods which have been shown to have positive effects on the healing process after CABG and postoperative complications. The aim of this study was to evaluate the efficacy of PBM in patients who underwent a coronary artery bypass graft (CABG). Ths study was conducted with 192 volunteers who electively submitted to CABG. The volunteers were randomly allocated into two groups: laser-treated (transdermal: 980 nm, 200 mW, continuous, average energy fluency of 6 J/cm2 and intravenous: 405 nm, 1.5 mW, continuous for 30 min) and standard treatment and control group (standard treatment only). Intravenous laser was illuminated the day before the surgery, immediately after transferring the patient to CCU post-operation and IV laser in addition to transdermal laser was applied every day after surgery for 6 days. A total of 170 out of 192 participants completed the study, 82 (48.2%) in the PBM group and 88 (51.8%) in the control group. Level of LDH and CPK was significantly lower in the PBM group (P < 0.05) in the 4th day postoperatively. The PBM group also showed significantly lower post-surgery complications, including pericardial effusion, ejection fraction, pathologic ST changes, pathologic Q, rehospitalization, heart failure, and mediastinitis (P < 0.05). Likewise, the VAS pain score after surgery was significantly lower in patients in the laser group (P < 0.05). PBM seems a promising, safe, cost-benefit therapeutic modality to reduce postoperative complications of CABG. Trial registration number: IRCT2016052926069N4 .
