Methods: We retrospectively reviewed data of all consecutive patients who underwent elective CABG, performed by the same surgeon, from January 2003 to October 2009. A propensity score analysis was carried out to adjust for baseline characteristics and a total of 398 patients were included: ONBHCAB (n = 181), OPCAB (n = 217). Results: OPCAB was associated with significantly shorter ventilation times (p < 0.001), intensive care unit stay (p < 0.001) and hospital stay (p < 0.001). The total blood loss was significantly more in the ONBHCAB group (p < 0.001), and accordingly, the number of transfused blood units was significantly lower in the OPCAB group (p < 0.001). Incidence of peri-operative renal complications were significantly higher in the ONBHCAB group (p = 0.004). The OPCAB group showed significantly lower long-term MACE-free survival (p = 0.029). The mean number of transfused blood units was the only independent predictor of MACE (HR: 1.218, 95% CI: 1.089-1.361; p = 0.001). Conclusion: OPCAB provided better long-term MACE-free survival compared with ONBHCAB. Fewer units of blood transfused following OPCAB surgery may have been the main reason for this result.eninfo:eu-repo/semantics/closedAccessCardiovascular system & cardiologyMajor cardiovascular eventOff-pump coronary artery bypass graftingOn-pump beating heartCardiac-surgeryTransfusion requirementsRandomized-trialsRisk patientsMetaanalysisMortalityBloodMorbidityRevascularizationBiomarkersCoronary angiographyCoronary artery bypassCoronary artery bypass, off-pumpCoronary artery diseaseFemaleFollow-up studiesHumansMaleMiddle agedPostoperative complicationsPrognosisRetrospective studiesSurvival rateTime factorsTurkeyArticle0003972426000082-s2.0-85015350769303528127172146Cardiac & cardiovascular systemsOff Pump Coronary Surgery; Coronary Artery Bypass Graft; Bypass SurgeryAdultAgedBleedingBlood transfusionCardiovascular diseaseControlled studyCoronary artery bypass surgeryElective surgeryEvent free survivalFemaleHeart diseaseHumanIntensive careIntermethod comparisonKidney diseaseLength of stayLung ventilationMajor clinical studyMaleOff pump coronary surgeryOutcome assessmentPeroperative complicationPredictionPropensity scoreRetrospective studyReviewTreatment outcomeCoronary angiographyCoronary artery bypass graftCoronary artery diseaseFollow upMiddle agedMortalityOff pump coronary surgeryPostoperative complicationsProceduresPrognosisSurvival rateTime factorTrendsTurkey
