Abstract
Background
Intro-aortic balloon pump (IABP) is widely used in cardiac surgery patients nowadays. This study aimed to analyze the predictor of short-term survival in cardiac valvular surgery patients with intra-aortic balloon pump implantation.
Methods
This was a retrospective study and a total of 102 cardiac valvular surgery patients who received intra-aortic balloon pump implantation were consecutively included. We retrospectively collected the baseline characteristics and short-term outcomes. Baseline characteristics were compared between survivors with non-survivors, and logistic regression was performed to identify predictors for short-term mortality.
Results
Among all the patients, there were 71 (69.6%) patients successfully weaned from IABP and survived to discharge, the other 31 (30.4%) patients failed to wean from IABP and died within the first 30 days after surgery. When compared with non-survivors, survivors had a higher proportion of males (62% vs 32.3%, p = 0.006), a lower rate of Atrial fibrillation (38% vs 62%, p < 0.03). After IABP implantation, vasoactive drug use was significantly lower in survivors compared with non-survivors, and survivors showed significant improvements in cardiac function and urine volume. Univariate and multivariate logistic regression analysis indicated that atrial fibrillation and combined use of continuous renal replacement therapy (CRRT) were significant independent predictors for short-term mortality.
Conclusion
Timely implantation of IABP can improve patients’ cardiac and renal function and reduce the dosage of vasoactive drugs. Atrial fibrillation and combined use of CRRT are independent predictors for short-term mortality in patients who underwent cardiac valvular surgery with IABP implantation.
