Abstract

Background: Prophylactic use of intraaortic balloon pump (IABP) reduces hospital mortality in patients with left ventricular (LV) systolic dysfunction undergoing coronary artery bypass surgery (CABG); however, its association in patients with LV diastolic dysfunction is unclear. This retrospective study investigated the association between preoperative LV function and perioperative use of IABP in patients undergoing off-pump CABG (OPCAB) at a university hospital. Methods: 100 consecutive patients who underwent OPCAB between January 1, 2011 and August 31, 2014 were studied. Preoperative LV function was categorized into four groups based on LV systolic and diastolic function determined with preoperative transthoracic echocardiography. The use of IABP was reviewed from medical records. The Mann-Whitney test, Pearson chi-square test, or Fisher exact test were used. Results: Patients were categorized into the following groups: normal LV function (n = 43), isolated LV systolic dysfunction (n = 13), isolated LV diastolic dysfunction (n = 21), and combined LV systolic and diastolic dysfunction (n = 14). Intraoperative IABP use was significantly more frequent in patients with isolated LV systolic dysfunction, isolated LV diastolic dysfunction, and combined LV systolic and diastolic dysfunction than in those with normal LV function (P < .05). Furthermore, IABP was used more frequently in patients who developed combined LV systolic and diastolic dysfunction postoperatively (P < .05). Conclusion: Not only the presence of preoperative systolic dysfunction but also LV diastolic dysfunction in the presence of normal LV systolic function were associated with increased use of IABP during and after OPCAB.
