研究目的: |
本项单中心前瞻性队列研究旨在评估LV小尺寸是否能独立预测24个月随访期间的AF负荷进展。通过重复心律监测可评估负荷轨迹,事件发生时间模型将用于评估阈值跨越事件。此外,嵌套病例对照设计可对风险集内进展时间点的暴露对比进行详细评估,在保持时间效度的同时提高分析效率。通过整合结构表型与纵向负荷评估,本研究旨在阐明心室几何形态对AF疾病演变的贡献。 |

|
Objectives of Study: |
This single-center prospective cohort study aims to evaluate whether a small left ventricular (LV) size can independently predict the progression of atrial fibrillation (AF) burden during a 24-month follow-up period. The burden trajectory can be evaluated through repeated rhythm monitoring, and an event time model will be used to assess threshold-crossing events. In addition, a nested case-control design can be used to conduct a detailed assessment of the exposure contrast at the time points of progression within the risk set, improving the analysis efficiency while maintaining temporal validity. By integrating structural phenotypes and longitudinal burden assessment, this study aims to elucidate the contribution of ventricular geometry to the evolution of AF. |
