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.

主动脉内球囊泵植入心脏瓣膜手术患者短期生存的预测因素

背景

主动脉内球囊反搏器（IABP）目前广泛应用于心脏手术患者。本研究旨在分析主动脉内球囊泵植入心脏瓣膜手术患者短期生存的预测因素。

方法

这是一项回顾性研究，连续纳入102例接受主动脉内球囊泵植入的心脏瓣膜手术患者。我们回顾性收集了基线特征和短期结果。对幸存者与非幸存者之间的基线特征进行比较，并进行逻辑回归以确定短期死亡率的预测因素。

结果

所有患者中，71例（69.6%）患者成功戒断IABP并存活出院，其余31例（30.4%）患者未能戒断IABP并在术后30天内死亡。与非幸存者相比，幸存者的男性比例较高（62% vs 32.3%，p  = 0.006），心房颤动发生率较低（38% vs 62%，p  < 0.03）。IABP植入后，幸存者的血管活性药物使用量显着低于非幸存者，并且幸存者的心功能和尿量显着改善。单变量和多变量逻辑回归分析表明，房颤和联合使用连续肾脏替代疗法（CRRT）是短期死亡率的显着独立预测因子。

结论

及时植入IABP可以改善患者的心肾功能，减少血管活性药物的用量。心房颤动和联合使用 CRRT 是接受 IABP 植入心脏瓣膜手术的患者短期死亡率的独立预测因素。
