目的 探讨心房颤动(atrial fibrillation,AF)经导管射频消融术(radio frequency catheter ablation,RFCA)后患者体力活动关联因素的网络结构,识别术后活动干预的关键节点。方法 2024年9月至2025年4月,采用便利抽样法选取在上海市某三级甲等综合医院心内科成功接受RFCA的412例患者为研究对象,采用中文版多过程行为控制问卷(multi-process action control questionnaire,M-PAC)对其进行调查,应用正则化偏相关网络分析构建网络并对中心性指标进行探索。结果 网络分析显示,习惯与身份认知的相关性最为显著(r=0.39),工具性态度为核心节点(r_s=1.22),情感态度的可预测性较高(75.30%)。结论 在RFCA术后患者体力活动行为的关联因素中,习惯与身份认知呈现出较强的交互作用。以工具性态度为核心的干预措施,可能是促进术后早期体力活动启动的关键所在,医护人员可依据此实施精准促进策略。

Objective To explore the network structure of factors associated with physical activity in patients after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF), and to identify key targets for post-operative activity intervention. Methods From September 2024 to April 2025, convenience sampling was used to select 412 patients who successfully underwent RFCA in the cardiology department of a tertiary A general hospital in Shanghai.The Chinese version of the multi-process action control(M-PAC) questionnaire was used for investigation. A regularized partial correlation network analysis was performed to construct the network and explore centrality indices. Results Network analysis showed that the association between habit and identity cognition was the most significant (r=0.39).Instrumental attitude was the core node (r_s=1.22), and affective attitude had high predictability (75.30%). Conclusions Among the factors associated with physical activity behavior in post-RFCA patients, habit and identity cognition show a strong interaction.Intervention targeting instrumental attitude may be key to promoting early post-operative physical activity initiation.Medical staff can implement precise promotion strategies based on this finding.
