    AimThe aim of the present study was to investigate the predictive value of preoperative neutrophil-lymphocyte ratio (NLR) in postoperative saphenous vein graft patency in patients undergoing coronary artery bypass grafting (CABG) surgery.MethodWe retrospectively analyzed 444 patients who had undergone CABG and a further control coronary angiography due to recurrence of symptoms. The patients were divided into tertile groups according to the NLR. The primary end point was 50% saphenous vein graft stenosis or more or complete occlusion.ResultThe saphenous vein graft failure in the 3 groups based on NLR was 33%, 66.2%, and 79.1%, in the low-, middle- and high-risk groups, respectively. In multivariate regression modeling, current smoker, diabetes mellitus, target artery diameter <1.5 mm, and NLR independently predicted saphenous vein graft patency in patients after CABG.ConclusionPreoperative NLR is clearly an independent predictor of saphenous vein graft patency in patients after CABG.© The Author(s) 2013.
