研究目的: |
希望通过开展回顾性研究构建并验证一个能够相对准确、个体化预测双腔起搏器植入患者术后18个月内发生房性心律失常风险的机器学习模型,为实现精准化、前瞻性的术后管理提供数据支撑。为此,本研究拟达到以下具体目标: (1)构建一个多维度临床-器械数据库:系统性地收集并整合接受双腔起搏器植入术患者的基线资料、术前检查指标及术后早期起搏器监测数据,形成一个高质量、结构化的队列数据集。 (2)筛选与确定关键预测因子:基于上述数据库,运用统计学和机器学习方法,识别影响术后房性心律失常发生的独立危险因素,并对其重要性进行排序。 (3)开发与训练预测模型:应用机器学习算法构建预测模型,并通过内部验证,筛选出性能最优的最终模型。 |

Objectives of Study: |
We aim to develop and validate a machine learning model that can relatively accurately and individually predict the risk of atrial arrhythmias within 18 months after dual?chamber pacemaker implantation through a retrospective study, so as to provide data support for precise and prospective postoperative management.To this end, the present study intends to achieve the following specific objectives: (1) To construct a multidimensional clinical?device database: systematically collect and integrate baseline characteristics, preoperative examination indicators, and early postoperative pacemaker monitoring data of patients undergoing dual?chamber pacemaker implantation, to form a high?quality, structured cohort dataset. (2) To screen and identify key predictors: based on the above database, use statistical and machine learning methods to identify independent risk factors affecting the occurrence of postoperative atrial arrhythmias and rank their importance.(3) To develop and train the prediction model: construct a prediction model using machine learning algorithms, and select the final model with the best performance through internal validation. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究通过查阅患者电子病历、住院及门诊病历资料,收集人口学信息、既往病史、基线检查结果、手术相关资料及术后随访信息等。随访数据通过门诊定期随访、起搏器程控及电话随访等方式获取并填写CRF表。所有数据统一录入标准化电子病例报告表,由专人负责数据录入、核对与整理。研究过程中严格保护患者隐私,对个人信息进行匿名化处理,遵守相关伦理要求。所有研究数据妥善保存,仅授权研究人员因本研究目的使用,确保数据安全、规范、可溯源。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
In this study, demographic data, medical history, baseline examination results, surgery-related data, and postoperative follow-up information were collected by reviewing patients’ electronic medical records, inpatient and outpatient medical records. Follow-up data were obtained through regular outpatient follow-up, pacemaker interrogation and programming, and telephone follow-up, and documented in case report forms (CRFs). All data were uniformly entered into standardized electronic case report forms and were input, checked, and organized by dedicated researchers. Patient privacy was strictly protected during the study, and personal information was anonymized in compliance with relevant ethical requirements. All study data were properly preserved and accessible only to authorized researchers for the purpose of this study, ensuring data security, standardization, and traceability. |
