研究目的:

主要目的: 1. 基于回顾性数据构建HOCM患者术后房颤风险预测模型并内部验证。 2. 在前瞻性队列中对模型进行独立验证与校准评估。 次要目的:比较ML与传统模型性能、评估亚组稳定性、探索关键预测因子等。  

Objectives of Study:

Primary Objectives: 1. To develop and internally validate a POAF risk prediction model using retrospective data. 2. To independently validate and calibrate the model in a prospective cohort. Secondary Objectives: To compare ML vs. traditional models, assess subgroup stability, explore key predictors, etc.
