About this study

Official title: The Impact of Autonomic Function on Recurrence Following Circumferential Pulmonary Vein Ablation for Atrial Fibrillation

This is a prospective and observational study. The investigator speculated that the use of DC in patients with paroxysmal AF can serve as a predictor for early and late AF recurrence following CPVI.

Read the detailed description

Atrial fibrillation (AF), also known as atrial flutter, is one of the most common cardiac arrhythmias and poses a serious threat to patients' health and well-being. The mechanism of AF is complex, with the autonomic nervous system playing a crucial role in its initiation and maintenance. Currently, medication and ablation are the main treatment methods to reduce AF episodes, but the efficacy of drug therapy is limited, and recurrence after ablation still exists. Recent studies have found that changes in autonomic nervous system activity are one of the key factors contributing to AF recurrence after ablation. Therefore, by objectively assessing changes in autonomic nervous system activity, it is expected to improve the success rate of AF ablation and provide a potential cure for AF, with significant social and economic value.

Studies have found that pulmonary vein isolation (PVI) ablation is the mainstream method for AF ablation, and it affects the autonomic nervous system function. Patients who show significant changes in autonomic nervous system function after AF ablation have higher success rates. Additionally, early-onset atrial arrhythmias are closely related to long-term AF recurrence after ablation. However, the mechanisms underlying early recurrence still require further investigation.

Our research team has conducted in-depth studies on the regulation of autonomic nervous system function in the heart and non-invasive assessment techniques, achieving breakthrough progress. The left atrial ganglion plays a crucial role in the initiation and maintenance of AF, and ablating the ganglion can improve the success rate of AF ablation. Non-invasive assessment techniques such as heart rate deceleration can quantitatively evaluate changes in vagal nerve activity in the heart, which can be used to predict the efficacy of autonomic ganglion intervention therapy.

Based on the above research, our research team hypothesizes that precise and quantitative assessment of autonomic nervous system function using heart rate deceleration can predict AF recurrence after PVI ablation. To validate this hypothesis, we plan to conduct a prospective observational study, recruiting patients with paroxysmal AF, assessing changes in autonomic nervous system function, monitoring early-onset atrial arrhythmias and AF recurrence, and providing theoretical support for the screening and intervention of high-risk recurrence patients, laying a foundation for clinical application.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Circumferential Pulmonary Vein IsolationProcedure or surgery

    Circumferential pulmonary vein isolation (CPVI) is a type of cardiac ablation procedure. Cardiac ablation procedures involve creating small scars in the heart using thermal or cold energy to block irregular electrical signals and restore normal heart rhythm. CPVI specifically creates small scars in the area where the four pulmonary veins connect to the left atrium of the heart. The pulmonary veins carry oxygen-rich blood from the lungs to the heart.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recurrence of AF at 1 year after surgery

    Standard 12-lead surface electrocardiogram (ECG) and 24-hour ECG monitoring

    Measured: 12 months after CPVI

  2. Autonomic nerve function assessment

    The difference in DC values at 1 year compared to the preoperative baseline

    Measured: 12 months after CPVI
