BACKGROUND: Cardiogenic shock after cardiac surgery leads to severely increased mortality. Intra-aortic balloon pumps may be used during the preoperative period to increase coronary perfusion. The purpose of this study was to characterize predictors of postoperative cardiogenic shock in cardiac surgery patients with and without intra-aortic balloon pumps support.
METHODS: We performed a retrospective analysis of our institutional database of the Society of Thoracic Surgeons for patients operated between January 2008 to July 2015. Multivariable logistic regression was used to model postoperative cardiogenic shock in both the intra-aortic balloon pumps and matched control cohorts.
RESULTS: Overall, 4,741 cardiac surgery patients were identified during the study period, of whom 192 (4%) received a preoperative intra-aortic balloon pump. Intra-aortic balloon pumps patients had a greater prevalence of diabetes, previous cardiac surgery, congestive heart failure, and an urgent/emergent status (P < .001). Intra-aortic balloon pumps patients also had greater 30-day mortality and more postoperative cardiogenic shock (9% vs 3%, P < .001). On multivariable analysis of the matched control cohort, postoperative cardiogenic shock remained multifactorial. Among the intra-aortic balloon pumps cohort, only sex, previous percutaneous coronary intervention and preoperative arrhythmia remained significant on multivariable analysis (all P < .05).
CONCLUSION: Factors associated with cardiogenic shock among postcardiac surgery patients differ between those patients receiving intra-aortic balloon pumps and those who do not. Further analysis of the effects of prophylactic intra-aortic balloon pumps support is warranted. (Surgery 2017;160:XXX-XXX.).
