AIM-AHEAD Data Bridge from MedStar Health
Cardiac Imaging Dataset
This dataset comprises electronic health records (EHR) of patients accompanied by heart echocardiogram images. The patients are evenly divided into two groups: Case and Control. Case indicates that there is a confirmed heart cancer diagnosis of this patient, while Control means no diagnosis of cancer. The dataset includes approximately 1,000 patients, and patients are further split into approximately 500 Cases and 500 Controls. The structured EHR data encompasses a wide range of information, including demographics, encounters, diagnoses, lab results, medications, vital signs, problem lists, procedures, and social determinants of health events. Additionally, radiology and pathology reports are available.
