ABSTRACT
OBJECTIVES: The study was aimed at investigating the risk factors of using an intraaortic balloon pump (IABP) in coronary artery bypass surgery and presenting the authors' clinical experience of IABP use. MATERIAL AND METHODS: The study included 1094 patients who underwent coronary artery bypass surgery at the authors' clinic between January 2009 and December 2011. A comparison was made between 17 patients in whom an IABP was used and 1077 patients in whom it was not used. RESULTS: An intraaortic balloon pump was used in 17 patients (1.55%) out of 1094 patients who underwent isolated coronary artery bypass surgery. The ratio of patients who had had preoperative myocardial infarction within the preceding 30 days, left main coronary artery stenosis of more than 50% and emergency surgery in Group 1 were higher than in Group 2 (p < 0.05). The total cardiopulmonary bypass time of Group 1 was found to be longer than that of Group 2 (p < 0.05). The demand for inotropics after weaning from cardiopulmonary bypass was greater in Group 1 than in Group 2 (p < 0.05). The need for reoperation (because of bleeding) was higher in Group 1 than in Group 2 (p < 0.05). The patients' stay on the intensive care unit was longer in Group 1 than in Group 2 (p < 0.05). Mortality rates were 29.4% in Group 1 and 1.2% in Group 2 (p < 0.05). CONCLUSIONS: Preoperative myocardial infarction within the preceding 30 days, left main coronary artery stenosis of more than 50%, emergency surgery and long cardiopulmonary bypass time are important risk factors for IABP use in coronary artery bypass surgery.
