EchoNotes Structured Database derived from MIMIC-III (ECHO-NOTE2NUM)

The EchoNotes Structured Database derived from MIMIC-III (ECHO-NOTE2NUM) is a structured echocardiogram database derived from 43,472 observational notes obtained during echocardiogram studies conducted in the intensive care unit at the Beth Israel Deaconess Medical Center between 2001 and 2012. The database encompasses various aspects of cardiac structure and function, including cavity size, wall thickness, systolic and diastolic function, valve regurgitation and stenosis, as well as pulmonary pressures. To facilitate extensive data analysis, the clinical notes were transformed into a structured numerical format. Within each echocardiogram report sentence, specific words or phrases were identified to describe abnormal findings, and a severity staging system using numeric categories was established. This large publicly-accessible database of structured echocardiogram data holds significant potential as a tool to investigate cardiovascular disease in the intensive care unit.

EchoNotes 结构化数据库，源自 MIMIC-III 数据集（ECHO-NOTE2NUM），系由贝斯以色列女执事医疗中心重症监护单元在 2001 至 2012 年期间进行的心脏超声检查所获取的 43,472 条观察性笔记构建而成。该数据库涵盖了心脏结构及功能的多方面内容，包括心腔大小、壁厚、收缩与舒张功能、瓣膜反流与狭窄，以及肺动脉压力等。为便于进行广泛的数据分析，临床笔记被转化为结构化的数值格式。在每份心脏超声报告的句子中，均识别出特定的词汇或短语，以描述异常发现，并建立了基于数值类别的严重程度分级系统。这一庞大的公共可访问结构化心脏超声数据库，具备作为研究重症监护单元中心血管疾病工具的巨大潜力。
