Arrhythmias & electrophysiologyCase-control study
Machine learning-based prediction of sudden cardiac death in the general population using electronic health record data
- Case-control study (machine learning prediction model development and external validation)
- temporal external validation
- geographical external validation
Authors' conclusion
We propose a prediction model designed to identify individuals at high risk of SCD among the general population.
Study context
- Population
- General population; Sudden cardiac death (SCD) cases and controls from electronic health record (EHR) data, Greater Paris and University of Washington (Seattle, USA)training 12,338 cases + 12,338 controls
- Outcome
- Discrimination of SCD (AUC)
- Follow-up
- 5 years preceding SCD
Main finding
As reported in the abstract
SCD prediction (AUC)
AUC, temporal validation cohort
0.81 (95% CI 0.80-0.82)
AUC, geographical cohort
0.66 (95% CI 0.58-0.73)
SCD detected in highest decile, Paris
26%
SCD detected in highest decile, Seattle
33%
Observational data: associations, not effects.
Further findings
No CV diagnoses in 5 years preceding SCD
- Subjects with no CV diagnosis
- 25.7%
MI prediction
- Model specific to SCD; not predictive of MI
