研究目的: |
心房颤动(下文简称“房颤”)是最常见的心律失常之一。射频消融术已被证实是有效的维持窦性心律的治疗方法。然而,射频消融术后房颤复发是一个常见的临床问题。一些研究表明,首次消融术后心房颤动的复发率为40%至70%。而导管消融术后房颤的复发是由各种因素的复杂相互作用所驱动的,包括房颤持续时间、年龄、左心房的大小,以及结构因素,如心外膜脂肪组织的增加、从电学或形态学标记物中可见的明显的心房底物的存在等。 近年来,研究表明射频消融术导致的心肌瘢痕是左心房顺应性降低和肺动脉压力升高的潜在原因。肺动脉高压会引起右心房压增大,继发性引起右心房电生理重塑,成为房颤发生的基础。已有的研究证明,复发房颤的患者中,肺动脉压力升高与非肺静脉房性心动过速有关。肺动脉压力高是持续性房颤患者导管射频消融术后复发的独立预测因子。然而,房颤消融术前后的肺动脉压力变化值与房颤复发的相关性还缺乏研究。房颤消融术前后的肺动脉压力变化是否能够预测房颤复发?能否通过干预肺动脉压力的变化来减少房颤复发的不利影响? 综上,本研究旨在通过单中心数据,探究房颤患者射频消融术术前和术后的肺动脉压力变化值与房颤复发的相关性及其预测价值。 |

Objectives of Study: |
Atrial fibrillation is one of the most common arrhythmias. Radiofrequency ablation has been proved to be an effective treatment method for maintaining sinus rhythm. However, the recurrence of atrial fibrillation after radiofrequency ablation is a common clinical issue. Some studies have indicated that the recurrence rate of atrial fibrillation after the first ablation procedure ranges from 40% to 70%. The recurrence of atrial fibrillation after catheter ablation is driven by the complex interplay of various factors, including the duration of atrial fibrillation, age, the size of the left atrium, and structural factors such as increased epicardial fat tissue, and the presence of significant atrial substrates visible from electrical or morphological markers. In recent years, studies have shown that the myocardial scars caused by radiofrequency ablation could be potential causes for decreased compliance of the left atrium and increased pulmonary arterial pressure. Pulmonary hypertension can cause an increase in right atrial pressure, which in turn, leads to electrophysiological remodeling of the right atrium, laying the groundwork for the occurrence of atrial fibrillation. Existing research has demonstrated that in patients with recurrent atrial fibrillation, increased pulmonary artery pressure is associated with non-pulmonary vein atrial tachycardia. High pulmonary artery pressure is an independent predictor for the recurrence of persistent atrial fibrillation after catheter radiofrequency ablation. However, there is a lack of research on the correlation between changes in pulmonary artery pressure before and after atrial fibrillation ablation surgery and the recurrence of atrial fibrillation. Can changes in pulmonary artery pressure before and after atrial fibrillation ablation surgery predict the recurrence of atrial fibrillation? Can intervening in changes in pulmonary artery pressure reduce the adverse effects of atrial fibrillation recurrence? Therefore, this study aims to explore the correlation and predictive value of changes in pulmonary artery pressure before and after radiofrequency ablation in patients with atrial fibrillation through single center data. |
