Abstract

Background

Recent data showed an association between malnutrition and increased all-cause mortality and thromboembolic risk in patients with atrial fibrillation (AF). However, the impact of malnutrition on the clinical outcomes for patients undergoing catheter ablation for AF is still debated. Our study aimed to examine this relationship using all existing available data.

Methods

We conducted a systematic review of MEDLINE and EMBASE databases from inception to April 2024, analyzing the association between malnutrition, assessed by the Geriatric Nutritional Risk Index (GNRI), and the risk of AF recurrence in patients who underwent catheter ablation for AF, compared to those without malnutrition. Relative Risk (RR) or hazard ratio (HR) and 95% CIs were retrieved from each study and combined using the generic inverse variance method.

Results

We included 3 cohort studies with 1697 participants undergoing AF ablation (10.9%) who had malnutrition indicated by GNRI score below 98. Patients with malnutrition had a higher risk of AF recurrence following catheter ablation for AF compared to those without malnutrition (Pooled RR = 2.74, 95% CI 1.36–5.51, I² = 67%, p = .005).

Conclusions

Our pooled analysis indicates that malnourished patients undergoing catheter ablation for AF have an increased risk of AF recurrence compared to non-malnourished patients.

导管消融后营养不良与房颤复发的风险。

背景：最近的数据显示，营养不良与房颤（AF）患者全因死亡率和血栓栓塞风险增加之间存在关联。然而，营养不良对房颤导管消融患者临床结果的影响仍存在争议。我们的研究旨在利用所有现有的可用数据来检验这种关系。方法：我们对MEDLINE和EMBASE数据库进行了系统回顾，从建立到2024年4月，分析营养不良（由老年营养风险指数（GNRI）评估）与房间隔导管消融患者房间隔复发风险之间的关系，与没有营养不良的患者相比。从每个研究中检索相对危险度（RR）或危险比（HR）和95% ci，并使用通用反方差法进行合并。结果：我们纳入了3项队列研究，1697名（10.9%）GNRI评分低于98的营养不良患者接受房颤消融治疗。与没有营养不良的患者相比，营养不良患者在房颤导管消融后房颤复发的风险更高（合并RR = 2.74, 95% CI 1.36-5.51, i2 = 67%, p = 0.005）。结论：我们的综合分析表明，与非营养不良患者相比，接受房颤导管消融治疗的营养不良患者房颤复发的风险增加。
