Background: Coronary artery bypass grafting is still a therapy of choice for complex ischemic heart disease. The purpose of the study was to compare the relation between obesity and blood flow through aorto-coronary bypass grafts with coexisting preoperative inflammatory state presented neutrophil-to-lymphocyte and platelets-to-lymphocyte ratios in retrospective analysis. Methods: We analyzed 50 consecutive patients (mean age 65 +/- 8) who underwent off-pump coronary artery bypass grafting (OPCAB) in our department in 2018. Graft blood flow measurements, as well as platelet-to-lymphocyte (PLR) and neutrophil-to-lymphocyte (NLR) ratios were evaluated. Results: Obese patients undergoing arterial revascularization were characterized by statistically significant lower arterial grafts flow for RIMA (p=0.0043), LIMA (p=0.0023) and RA (p=0.0214) with satisfactory medium term (897 +/- 123 days) results. The chronic inflammatory parameters including NLR and PLR were significantly differed between obese and non-obese patients (p=0.0312 and p=0.0003, respectively) referred for surgery. The inverse correlation between BMI and NLR (r=0.307) and PLR(r=0.413) was noted. Conclusion: Obese patients referred for CABG present a decreased graft blood flow velocity combined with an increased neutrophil-to-lymphocyte and platelet-to-lymphocyte ratio.

Pump Coronary Artery Bypass

The beneficial effects of intraaortic balloon pump (IABP) in coronary artery bypass graft surgery with cardiopulmonary bypass have been reported. However, whether preoperative insertion of IABP in high-risk off-pump coronary artery bypass grafting (OPCAB) has any beneficial effects remains to be established. We report our experience of preoperative insertion of IABP in OPCAB.
