The aim of this study was to identify preoperative and intraoperative factors that may predict prolonged ICU requirement in patients undergoing isolated CABG and to evaluate the impact of minimally invasive extracorporeal circulation (MiECC) utilization on this outcome. Materials and Methods: Patients who underwent isolated CABG between January 2024 and April 2025 were retrospectively analyzed. Prolonged ICU stay was defined as a postoperative intensive care duration exceeding 72 h. Predictors of prolonged ICU stay were evaluated using univariate logistic regression and four multivariable logistic regression models. Receiver operating characteristic (ROC) curve analyses were performed to assess the discriminative performance of significant and clinically relevant variables as well as the multivariable models. Results: A total of 82 patients were included and stratified into a prolonged ICU stay group (n = 32) and a non-prolonged ICU stay group (n = 50). The preoperative left ventricular ejection fraction (LVEF) was significantly lower (52.5% vs. 60%, p = 0.012) and preoperative leukocyte counts significantly elevated (8.4 vs. 7.97 \u00d7 103\/\u00b5L, p = 0.049) in the prolonged stay group. MiECC was employed in 28.1% of patients with a prolonged ICU stay and 30% of those with a non-prolonged stay (p = 0.530). Across four multivariable logistic regression models, lower preoperative ejection fraction and higher preoperative leukocyte count were identified as independent predictors of prolonged ICU stay, whereas MiECC utilization was not independently associated with this outcome. Conclusions: Lower preoperative ejection fraction and higher baseline leukocyte count were independently associated with prolonged ICU stay. No independent association between MiECC utilization and prolonged ICU stay could be demonstrated. These findings suggest that preoperative cardiac function and inflammatory status may contribute to ICU requirements following isolated CABG. Further prospective studies are warranted to validate these findings.<\/jats:p>","DOI":"10.3390\/medicina62071289","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T11:39:11Z","timestamp":1783078751000},"page":"1289","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Predictors of Prolonged ICU Stay After Isolated CABG: The Role of MiECC"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5735-4473","authenticated-orcid":false,"given":"Alper","family":"\u00d6zbakkalo\u011flu","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4248-2867","authenticated-orcid":false,"given":"\u00d6mer Faruk","family":"Rahman","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mert","family":"Arslangilay","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ercan","family":"Kele\u015f","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6nder Turgut","family":"Bozkurt","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Da\u011flar","family":"Cansu","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1256-5055","authenticated-orcid":false,"given":"\u015eahin","family":"Bozok","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, \u0130zmir Bak\u0131r\u00e7ay University, Menemen 35665, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3415","DOI":"10.1093\/eurheartj\/ehae177","article-title":"2024 ESC Guidelines for the management of chronic coronary syndromes: Developed by the task force for the management of chronic coronary syndromes of the European Society of Cardiology (ESC) Endorsed by the European Association for Cardio-Thoracic Surgery (EACTS)","volume":"45","author":"Vrints","year":"2024","journal-title":"Eur.
