研究目的:

在我们既往研究的基础上,明确Lp(a)是否可介导人AMI后心肌炎症、坏死、纤维化等不良心室重塑,从而导致HF的发生,并试图解析其可能的病理生理机制;为AMI后不良心室重塑和HF的发生发掘新的危险因素,并将其转化为临床实践,用于指导该人群的危险分层和诊疗决策,为AMI后HF的防治提供可能的早期干预靶标。  

Objectives of Study:

Based on our previous research, we plan to investigate whether lipoprotein(a) [Lp(a)] can mediate adverse ventricular remodeling after acute myocardial infarction (AMI), including myocardial inflammation, necrosis, and fibrosis, leading to the occurrence of heart failure (HF). We also strive to elucidate the potential pathophysiological mechanisms underlying this process. Therefore, this study aims to identify new risk factors of adverse ventricular remodeling and HF after AMI, translate these findings into clinical practice, and guide risk stratification and treatment decisions for AMI population. Ultimately, we hope to provide potential early intervention targets for the prevention and treatment of HF following AMI.

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:

为了保证数据采集质量的准确性和真实性,研究团队统一进行数据质控培训。本研究数据来源于阜外医院信息化病案管理系统及研究者采集的随访数据,信息化提取阜外病例系统中的病历数据,整理采集的随访数据,建立数据库。数据导出过程遵循保密原则,导出的数据库由本研究的研究者在不连接外网的电脑单独存储,确保数据库不对外泄漏。随访调查过程中,由指定的研究医生负责随访数据的采集和录入。数据将采取双人录入,对录入结果进行识别缺失值、异常值以及逻辑错误等问题,有效避免数据录入过程中的错误,通过软件数据比对功能合并数据库。

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

To ensure the accuracy and authenticity of data collection, the research team have undergone unified data quality control training. The data of this study originate from the informatized medical record management system of Fuwai Hospital and the follow-up data are collected by researchers. We extract the medical record data from the Fuwai Hospital case system through information technology, organize the collected follow-up data, and establish a database. The data export process adheres to the confidentiality principle, and the exported database is stored separately by the researchers of this study on computers that are not connected to the internet, ensuring that the database will not be leaked to the outside. During the follow-up investigation, designated research doctors are responsible for collecting and entering the follow-up data. The data will be entered by two researchers and the database will be checked for missing values, abnormal values, and logical errors, to avoid errors in the data entry process. The database will be merged through the data comparison function of the software.
