Beneficial effect of preoperative intraaortic balloon pumping (IABP) treatment in high-risk patients who had open heart surgery have been demonstrated. The purpose of this study is to determine the impact of preoperative IABP use on survival in high-risk patients undergoing coronary artery bypass grafting (CABG). Two hundred seventy-seven consecutive patients having CABG at our institution were reviewed. Patients having an IABP were identified retrospectively and grouped into one of 3 groups as follows. Group A (n = 14): preoperative IABP for high-risk urgent or elective cases. Group B (n = 26): preoperative IABP for emergency cases. Group C (n = 6): unplanned intraoperative or postoperative IABP. Forty-six patients had an IABP (16.6% of total). Parsonnet score in group B was significantly higher (p < 0.05). Length of operation for group C was significantly longer (p < 0.05). Overall hospital mortality in the total group of 277 cases was 4.2%. Hospital mortality was 7.1% in group A, 7.7% in group B, and 50% in group C. Hospital mortality in group C was significantly higher (p < 0.01). The beneficial effect of preoperative treatment with IABP in high-risk patients undergoing CABG was confirmed. This approach resulted in a significantly lower hospital mortality.
