研究目的:

心肌梗死后的机械并发症 (PIVSR与PIPMR)进展迅猛死亡率极高,是临床最具挑战性的急危重症之一。目前缺乏针对该类患者短期预后的有效风险预测工具,亟需结合现代智能算法手段,开发精准、可解释的预测模型,以辅助临床快速识别高危人群、优化救治路径。因此,本研究拟开展如下目标: 主要研究目的:基于真实世界临床数据,构建并验证适用于心肌梗死后机械并发症(PIVSR与PIPMR)患者的短期死亡风险预测模型,提升高危患者的早期识别能力,为临床干预决策提供量化支持。 次要研究目的:系统分析影响PIVSR与PIPMR患者30天内死亡风险的关键临床因素;比较多种变量筛选方法及机器学习算法在模型性能上的差异,筛选最优建模策略;运用可解释性机器学习方法(如SHAP)揭示各预测因子对死亡风险的贡献,提升模型临床可解释性与应用价值;初步探索不同治疗手段(如手术干预、循环辅助等)与患者短期预后的相关性。  

Objectives of Study:

Post–myocardial infarction mechanical complications (PIVSR and PIPMR) progress rapidly and carry extremely high mortality, representing one of the most challenging critical emergencies in clinical practice. Currently, there is a lack of effective risk prediction tools for short-term prognosis in this population. There is an urgent need to leverage modern artificial intelligence techniques to develop accurate and interpretable predictive models that facilitate rapid identification of high-risk patients and optimize clinical decision-making pathways. Primary Objective: To construct and validate a short-term mortality prediction model for patients with post–myocardial infarction mechanical complications (PIVSR and PIPMR) based on real-world clinical data, with the aim of improving early detection of high-risk individuals and providing quantitative support for clinical intervention decisions. Secondary Objectives: To systematically analyze key clinical determinants associated with 30-day mortality in PIVSR and PIPMR patients; to compare the performance differences among multiple feature selection strategies and machine learning algorithms to determine the optimal modeling approach; to apply explainable AI techniques (e.g., SHAP) to elucidate the contribution of individual predictors and enhance model interpretability and clinical applicability; and to preliminarily explore the association between different treatment strategies (e.g., surgical intervention, circulatory support) and short-term outcomes.

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:

数据采集由两名经统一培训的独立研究人员执行,采用事先设计并标准化的病例记录表(Case Record Form,CRF),对所有符合纳入标准的患者进行结构化信息提取。提取内容包括人口学信息、基础疾病与既往病史、实验室检查指标、心功能评估与影像学资料、治疗措施以及短期临床结局等。所有数据将采取双人独立录入与交叉核对,以确保准确性与一致性。 在数据管理方面,本研究使用院内安全可控的电子数据采集与管理系统(Electronic Data Capture,EDC),该系统具备权限分级、操作日志与数据追溯功能。在录入过程中,如遇缺失或疑义数据,将回溯原始病历进行核实与补充;若最终无法获取,则在数据库中作缺失标记,并在后续统计分析中采用适当方法处理。整个数据采集与管理过程均按照事先制定的标准操作流程执行,并由研究负责人定期监督质控。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection was conducted by two independent researchers who had undergone standardized training, using a pre-designed and standardized Case Record Form (CRF) to extract structured information from all eligible patients. The collected variables included demographic characteristics, comorbidities and medical history, laboratory findings, cardiac function assessments and imaging data, treatment strategies, and short-term clinical outcomes. A double-entry and cross-checking procedure was implemented to ensure data accuracy and consistency. For data management, a secure institutional Electronic Data Capture (EDC) system was utilized, which supports access control, audit trails, and full traceability. Any missing or ambiguous data were verified and supplemented by reviewing the original medical records; if the information could not be retrieved, it was clearly marked as missing in the database and handled appropriately during subsequent statistical analysis. All data collection and management procedures followed a predefined standard operating protocol and were regularly monitored by the principal investigator for quality control.
