研究目的: |
本研究旨在基于冠心病合并心力衰竭患者经皮冠状动脉介入治疗(PCI)术后的临床数据,通过 LASSO 联合递归特征消除(RFE)策略筛选预后关键特征,构建并验证以 XGBoost 为核心的机器学习预测模型,评估模型对主要不良心血管事件(MACE)的预测效能、校准度与临床可解释性,建立科学的风险分层体系,识别术后高危与极高危人群,为临床个体化随访管理与精准干预策略提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aimed to develop and validate a machine learning–based prognostic prediction model for major adverse cardiovascular events in patients with coronary heart disease complicated by heart failure after percutaneous coronary intervention (PCI), screen key prognostic features using the LASSO-RFE strategy, evaluate model performance, calibration and interpretability, establish a risk stratification system, and provide evidence for individualized follow-up and precise clinical intervention. |

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: |
本研究建立规范的数据采集与管理体系,保障数据真实、完整、准确、可追溯。设计标准化病例记录表(Case Record Form, CRF),由经培训的研究人员如实采集患者基线、手术、检查、用药及随访等全流程临床数据;搭建专用电子数据采集(Electronic Data Capture, EDC)系统,内置多重质控规则,实现数据电子化录入、核查与闭环管理。采用双人双录入模式保障录入准确性,对所有数据进行匿名化处理,分级权限存储以保护患者隐私。通过门诊、电话及病历回溯开展标准化随访,完整记录终点事件信息,成立数据管理委员会全程监督审计,确保数据管理符合临床研究规范。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study establishes a standardized data collection and management system to ensure the authenticity, completeness, accuracy and traceability of data. A standardized Case Record Form (CRF) is designed, and trained researchers will truthfully collect the full-process clinical data of patients, including baseline characteristics, surgical information, laboratory and imaging results, medication regimens and follow-up data. A dedicated Electronic Data Capture (EDC) system is built with multiple built-in quality control rules to realize electronic data entry, verification and closed-loop management. Double data entry by two independent researchers is adopted to ensure entry accuracy. All data are anonymized and stored with hierarchical access rights to protect patient privacy. Standardized follow-up is conducted through outpatient review, telephone contact and medical record review to completely record endpoint events. A data management committee is established to conduct full-process supervision and audit, ensuring that data management complies with clinical research specifications. |
