Insights
A new cardiovascular signal database was created for diagnosing ischaemic heart disease (IHD). This resource aids research by storing detailed patient data, including ECG and imaging, for comprehensive analysis.
Area of Science:
- Cardiology
- Medical Informatics
- Biomedical Signal Processing
Background:
- Ischaemic heart disease (IHD) diagnosis requires comprehensive patient data.
- Existing cardiovascular signal repositories may lack integrated multi-modal data.
- Standardized data collection is crucial for advancing cardiovascular research.
Purpose of the Study:
- To develop a novel, comprehensive database of cardiovascular signals.
- To facilitate research on ischaemic heart disease (IHD) using integrated patient data.
- To establish a standardized repository for cardiovascular signal analysis.
Main Methods:
- Collected cardiovascular signals (12-lead ECG, arterial blood pressure, respiration) during stress tests.
- Integrated diagnostic imaging (echo, radionuclide) and pharmacological test data.
- Stored annotated beat-by-beat signals, image frames, clinical records, and arteriography data for 50 patients.
Main Results:
- A new database containing detailed cardiovascular signals and associated clinical information for suspected IHD patients has been established.
- The database includes non-invasively measured signals during stress testing and diagnostic imaging.
- Data is archived on CD-ROM with beat-by-beat annotations for detailed analysis.
Conclusions:
- The developed database provides a valuable resource for studying ischaemic heart disease.
- Integrated multi-modal data enhances the potential for accurate cardiovascular diagnosis and research.
- This initiative supports advancements in cardiovascular signal processing and clinical interpretation.
Abstract:
A new database of cardiovascular signals has recently been developed at the CNR Institute of Clinical Physiology in a study based on patients admitted to the Coronary Care Unit for suspected ischaemic heart disease (IHD), who underwent both ECG effort stress test and echo or radionuclide diagnostic imaging procedures associated with pharmacological test of myocardial ischaemia. During stress testing, in addition to 12-lead ECG, arterial blood pressure and respiration signals are measured non-invasively and recorded. Signals and representative image frames at baseline and during ischaemia are stored in the database, which is planned to include 50 cases, annotated beat by beat and archived on CD-ROM. Each case also contains resting ECG and a comprehensive patient clinical record; if possible Holter ECG and coronary arteriography frames.
