Abstract
BACKGROUND: There is limited guidance regarding the use of anticoagulation in patients on intra-aortic balloon pumps (IABP). The purpose of this study is to compare the safety outcomes in anticoagulated versus non-anticoagulated patients with an IABP. METHODS: This was a single center, retrospective chart review of patients admitted to the coronary care unit or cardiac surgery unit who received an IABP from May 2015 to July 2018. Patients who were anticoagulated with heparin while on an IABP were compared to those who were not anticoagulated. Major endpoints included a composite of thrombotic events and a composite of bleeding events. The major composite endpoint of thrombotic events included the incidence of ischemic stroke, any venous thromboembolism, device thrombosis, and limb ischemia. The major composite endpoint of bleeding events included major access site bleeding, minor access site bleeding, major non-access site bleeding, and minor non-access site bleeding. Minor endpoints included any major endpoint events occurring within 24 and 48 h of IABP insertion, hospital length of stay, intensive care unit length of stay, and in-hospital mortality. RESULTS: A total of 185 patients were evaluated for inclusion and 147 were included in the final analysis. There were 82 and 65 patients in the heparin and non-heparin groups, respectively. The composite endpoint of thrombotic events occurred in 7.3 and 7.7% in the heparin and non-heparin groups, respectively (p = 1). The composite bleeding endpoint occurred in 20.7 and 20.0% in the heparin and non-heparin groups, respectively (p = 0.91). There were no differences found in minor endpoints between groups. CONCLUSION: There were no significant differences found in major endpoints of bleeding and thrombotic events in patients who received anticoagulation while on an IABP versus those who did not receive anticoagulation.
