队列研究 

Study design:

Cohort study 

研究目的:

本研究拟利用回顾性队列数据,将临床相关指标与心脏周围脂肪的CT衰减值相融合,构建新型、高效的个体化复发风险预测模型,旨在填补“全身-局部”整合预测的空白,为临床决策及房颤患者术后个体化管理提供更精准的工具,并为“全身代谢异常通过局部脂肪炎症促进心房重构”的病理生理假说提供循证依据。  

Objectives of Study:

This study intends to use retrospective cohort data to integrate clinically relevant indicators with CT attenuation values of epicardial adipose tissue, and construct a novel and efficient individualized prediction model for recurrence risk. It aims to fill the gap in "systemic?local" integrated prediction, provide a more accurate tool for clinical decision?making and individualized postoperative management of patients with atrial fibrillation, and offer evidence?based support for the pathophysiological hypothesis that systemic metabolic abnormalities promote atrial remodeling through local adipose inflammation.

指标中文名:

心脏CT脂肪衰减值

指标类型:

主要指标

Outcome:

Cardiac CT fat attenuation value

Type:

Primary indicator

测量时间点:

房颤射频消融术后1年

测量方法:

基于术前CTA图像(DICOM格式从PACS导出),采用深度学习模型(SwinUNETR)自动分割左心房(LA)、左心耳(LAA)、左心室(LV)、右心房(RA)、右心室(RV)、肺静脉(PV)。使用PyRadiomics提取各ROI的影像组学特征

Measure time point of outcome:

One year after radiofrequency catheter ablation for atrial fibrillation

Measure method:

Based on preoperative CTA images (exported from PACS in DICOM format), a deep learning model (SwinUNETR) was used to automatically segment the left atrium (LA), left atrial appendage (LAA), left ventricle (LV), right atrium (RA), right ventricle (RV), and pulmonary veins (PV). Radiomic features of each ROI were extracted using PyRadiomics.
