Preoperative, postoperative (PO) 1st hour, PO 1st day, and PO 5th day neutrophil-lymphocyte ratios were calculated. The patients were compared, according to demographic, laboratory, and clinical data. A receiver operating characteristics curve was applied to estimate a cut-off value of NLR for mortality.\nResults: The on-pump group was older (P = 0.001), had a lower Euroscore II (P = 0.036), had a higher graft number (P &lt; 0.001), intensive care unit stay (P = 0.001), and all PO NLRs, except preoperative NLR. There were 14 (3.06%) patients with mortality. Overall (N = 457), PO 1st hour (P = 0.001), PO 1st day (P &lt; 0.001), and PO 5th day (P = 0.016) NLRs were considerably higher in patients with mortality. While none of the NLRs revealed a significant difference in the off-pump group, PO 1st hour (P = 0.004) PO 1st day (P &lt; 0.001), and PO 5th day (P = 0.007) NLRs were higher in patients with mortality in the on-pump group. The increase in odds ratio of PO NLR was higher in patients with mortality in the overall group of PO 1st day and in the on-pump group of PO 1st hour and PO 1st day. The best combination of sensitivity and specificity was reached at a cut-off value of 6.4 for PO 1st hour NLR and 31.8 for PO 1st day NLR.\nConclusions: As in indicator of inflammatory state, NLR readily can be used as a predictor of mortality. Regardless of the CABG technique used, postoperative 1st hour and postoperative 1st day NLR &gt;6.4 and 31.8, respectively, are highly related to mortality.<\/jats:p>","DOI":"10.1532\/hsf.4099","type":"journal-article","created":{"date-parts":[[2021,9,14]],"date-time":"2021-09-14T21:04:54Z","timestamp":1631653494000},"page":"E814-E820","source":"Crossref","is-referenced-by-count":11,"title":["Retrospective Evaluation of the Pre- and Postoperative Neutrophil-Lymphocyte Ratio as a Predictor of Mortality in Patients Who Underwent Coronary Artery Bypass Grafting"],"prefix":"10.31083","volume":"24","author":[{"given":"Aykut","family":"\u015eAHIN","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emrah","family":"Sisli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2021,9,14]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/4099\/7013","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/4099\/7013","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T10:15:48Z","timestamp":1766398548000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/24\/5\/10.1532\/hsf.4099"}},"subtitle":["Neutrophil-lymphocyte Ratio and Coronary Artery Bypass Grafting"],"short-title":[],"issued":{"date-parts":[[2021,9,14]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2021,9,8]]}},"URL":"https:\/\/doi.org\/10.1532\/hsf.4099","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"value":"1522-6662","type":"electronic"},{"value":"1098-3511","type":"print"}],"subject":[],"published":{"date-parts":[[2021,9,14]]}}}
