研究目的: |
主要目的:本项目以HFmrEF诊断的患者为研究对象,以机器学习方法为手段,开展HF恶化或心血管死亡风险因素评价与预测的回顾性研究,构建预测模型,旨在早期识别高危患者,精准指导临床治疗方案的制定,提高患者治疗效果,改善疾病预后,建立辅助决策机制,推广模型应用。 次要目的:观察研究队列观察结束时间点(再住院或死亡)时与初始时期(首次因心衰住院)的LVEF水平的差值,对该指标回归拟合;观察次要结局指标方面的发生率及相关风险因素分析。 |

|
Objectives of Study: |
Primary Objective: This project focuses on patients diagnosed with HFmrEF and employs machine learning methods to conduct a retrospective study on the evaluation and prediction of risk factors for HF exacerbation or cardiovascular death. The aim is to develop a predictive model that can identify high-risk patients early, precisely guide the formulation of clinical treatment plans, improve patient outcomes, enhance disease prognosis, establish an auxiliary decision-making mechanism, and promote the application of the model. Secondary Objective: To observe the difference in LVEF levels between the endpoint of the study cohort observation (rehospitalization or death) and the initial period (first hospitalization for heart failure), and perform regression fitting on this indicator. Additionally, to observe the incidence of secondary outcome indicators and analyze related risk factors. |

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: |
应用大数据平台进行数据采集,整理合并患者就诊资料最初时间的一般情况、合并症和治疗情况、就诊资料指定时间段内发生的不良事件等,对于存在缺失诊疗信息的部分变量进行数据处理,具体方式包括:①对于缺失>20%的单个变量进行删除处理;对于数据信息缺失>20%的研究对象进行删除处理;②对于缺失>5%但<20%的变量进行R语言软件多元插补法((Multiple Imputation by Chained Equations ,MICE))填补;具体为:连续变量缺失值用预测均值匹配(Predictive mean matching,PMM)算法,二分类变量用逻辑回归算法。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The big data platform was used to collect data, sort out and merge the general situation of the initial time of the patient's visit data, the comorbidities and treatment, and the adverse events that occurred within the specified time period of the visit data, and process the data of some variables with missing diagnosis and treatment information, including: (1) deleting a single variable with a missing > 20%; 20% of the research subjects with missing data and information > were deleted; (2) Multiple Imputation by Chained Equations (MICE) was used to fill in the missing >5% but <20% of the variables; Specifically, the Predictive mean matching (PMM) algorithm is used for the missing values of continuous variables, and the logistic regression algorithm is used for dichotomous variables. |
