摘要

背景：导管消融（CA）可以改善房颤（AF）患者的运动耐量和生活质量（QOL）。然而，其对阵发性房颤（PAF）和非阵发性房颤（Non-PAF）肌力的差异影响尚不清楚。方法：我们评估了94例（67.8±10.3岁，71%男性）行CA （PAF/Non-PAF 46/48）且无房颤复发的患者。在ca后的基线、3个月和6个月分别评估6分钟步行距离（6MWD）、腿部力量和af特异性生活质量问卷（AFQLQ）。结果：基线时，PAF患者的6MWD和AFQLQ亚群3评分明显低于非PAF患者，但两组之间的肌肉力量参数具有可比性。两组患者术后6个月6MWD和AFQLQ均有显著改善。然而，非PAF组在CA后6个月的腿部力量显著改善（54.9±16.5至58.4±15.2,p）。结论：PAF和非PAF的成功CA改善了生活质量和运动耐量。此外，CA改善了非paf患者的腿部力量。

Different effects of catheter ablation on exercise tolerance, leg strength, and quality of life in paroxysmal versus persistent atrial fibrillation

Background

Catheter ablation (CA) can improve exercise tolerance and quality of life (QOL) in patients with atrial fibrillation (AF). However, its differential effects on muscle strength between paroxysmal AF (PAF) and nonparoxysmal AF (Non-PAF) remain unclear.

Methods

We evaluated 94 patients (67.8 ± 10.3 years old, 71% male) who underwent CA (PAF/Non-PAF 46/48) without AF recurrence. Six-minute walk distance (6MWD), leg strength, and an AF-specific QOL questionnaire (AFQLQ) were evaluated at baseline, 3, and 6 months after CA.

Results

At baseline, the 6MWD and AFQLQ subset 3 score were significantly lower in patients with PAF than in those with Non-PAF, but the parameters of muscle strength were comparable between the two groups. Both 6MWD and AFQLQ significantly improved at 6 months after CA in both groups. However, leg strength at 6 months after CA significantly improved in the Non-PAF group (54.9 ± 16.5 to 58.4 ± 15.2, p < .05) but not in the PAF group.
