Key result
Among patients undergoing open heart surgery with intraaortic balloon pump support, hospital mortality was 21.89%, with complications occurring in 5.05%.
Cohort (n=475)
Hospital mortality in patients requiring perioperative IABP support during open heart surgery is 21.89%, with risk primarily driven by baseline comorbidities and postoperative complications rather than IABP-related complications.
High mortality in IABP-supported open heart surgery warrants cautious patient selection; cohort data leaves open IABP's independent contribution versus comorbidities.
Mechanical circulatory assistance is frequently needed to support the failing heart. The aim of this study was to determine perioperative prognostic factors for hospital mortality in patients undergoing open heart surgery who required intraaortic balloon pump support. Between January 2002 and September 2006, 475 patients received an intraaortic balloon pump perioperatively. Hospital mortality was 21.89%. Risk factors for hospital death identified by multivariate logistic regression analysis were peripheral vascular disease, left main coronary artery disease, postoperative renal failure, postoperative cardiac arrest, and prolonged hospital stay. Minor and major intraaortic balloon pump-related complications were not significant in univariate and multivariate analysis; the incidence was 5.05%. It is suggested that the threshold for using balloon pump support is decreased in high-risk patients undergoing cardiac surgery.

Karimi et al. (2008) conducted a cohort in Open heart surgery requiring intraaortic balloon pump support (n=475). Intraaortic balloon pump support was evaluated on Hospital mortality. Among patients undergoing open heart surgery with intraaortic balloon pump support, hospital mortality was 21.89%, with complications occurring in 5.05%.
