In this study, we examined the early results for patients who underwent beating heart coronary bypass surgery and compared these results with those of conventional coronary bypass surgery.A total of 1094 patients who underwent isolated coronary artery bypass surgery between January 2009 and December 2011 in our clinic were included in this study. Seventy-three patients in whom cardiopulmonary bypass was not used (group 1) were compared to 1021 patients in whom cardiopulmonary bypass was used (group 2).The mean age was 60.7 ± 9.3 in group 1 and 58.9 ± 9.7 in group 2 (P > 0.05). There was no significant difference between the two groups in terms of gender, or the coexistence of diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), and hypertension (P > 0.05). There was no significant difference between group 1 and group 2 in terms of development of postoperative atrial fibrillation (AF), use of an intra-aortic balloon pump, need for re-operation for bleeding, or duration of hospital stay and intensive care unit stay (P > 0.05). The need for inotropic support and the amount of mediastinal drainage were less in group 1 than in group 2 (P = 0.002, P 0.05). There was no mortality in group 1, whereas it was calculated as 1.8% in group 2 (P = 0.63).Beating heart coronary artery bypass surgery decreases the need for inotropic support and transfusion.
