New Database Provides Valuable Insights into Predicting Sudden Cardiac Death and Atrial Fibrillation
The BSICoS research group (Unit 27 of NANBIOSIS) shared 4 years of heart failure data from 1,000 patients on the Physionet portal for scientific use.
Zaragoza, December 2024. The BSICoS research group (Biomedical Signal Interpretation and Computational Simulation) from the Aragón Institute of Engineering Research (I3A), in whcih the Unit 27 of NANBIOSIS is located, has shared a clinical database containing information from 992 heart failure patients. These patients underwent a 24-hour electrocardiogram (ECG) recording and were monitored over a four-year period. This dataset enables advancements in research on predicting the risk of sudden cardiac death using Holter monitoring data.
The Sudden Cardiac Death in Heart Failure (MUSIC) multicenter study, involving eight hospitals across Spain, was designed to evaluate risk indicators for cardiac mortality and sudden cardiac death in individuals with chronic heart failure.
“[The study serves] to develop prognostic models to predict the risk of sudden death and cardiac death, apply the technologies we had, and seek new markers to improve the identification of high-risk patients for potential defibrillator implantation.”

The initial goal of the project was “to develop prognostic models to predict the risk of sudden death and cardiac death, apply the technologies we had, and seek new markers to improve the identification of high-risk patients for potential defibrillator implantation,” explains Alba Martín Yebra, a researcher from the BSICoS group.
The MUSIC database includes 24-hour Holter recordings, high-resolution ECG data, and clinical data from blood analysis, echocardiography, chest X-rays, and prescribed medications. The database is available on www.physionet.org, an open-access platform managed by the Massachusetts Institute of Technology (MIT) that hosts databases and open-source software for research purposes.
The work describing this database was presented at the latest edition of the “Computing in Cardiology” scientific conference held in Karlsruhe, Germany, where it garnered significant interest from researchers. “In our research group, working with this data allowed us to develop and validate new biomarkers for predicting sudden cardiac death. That’s why we decided to share it with the scientific community so that other groups can use it to validate and reproduce results in their research lines,” notes Alba Martín. Additionally, it serves as an invaluable testing ground for evaluating algorithms based on deep learning or artificial intelligence.
The MUSIC study has been utilized in various works. According to Alba Martín, the dataset “is a valuable resource for developing and evaluating a wide range of non-invasive prognostic biomarkers derived from the ECG.” One aspect that makes it particularly interesting is the four-year follow-up period, which documents patient evolution after data collection.
Specifically, the BSICoS group has evaluated parameters based on heart rate turbulence, T-wave morphology, and its dependence on heart rate. These parameters were assessed for predicting mortality due to arrhythmias and the progression of heart failure, proving to be powerful risk predictors.
Finally, MUSIC has served as proof of concept for developing new signal processing techniques for atrial fibrillation, an area where the BSICoS group has been a pioneer.
