Key result
Dynamic ECG remodelling improves SCD prediction beyond static ECG and clinical factors to ~0.87 AUC.
Why the study?
ECG abnormalities have been evaluated as static risk markers for sudden cardiac death, but the potential importance of dynamic ECG remodelling has not been investigated.
Does dynamic ECG remodelling improve the prediction of sudden cardiac death compared to static baseline ECG and clinical risk factors?
Comparison
SCD cases vs matched controls
Design

Does dynamic ECG remodelling improve the prediction of sudden cardiac death compared to static baseline ECG and clinical risk factors?
Effect estimate: AUC (95% CI 0.837-0.902)
Absolute Event Rate: 0.869% vs 0.77%
Dynamic ECG remodelling significantly improves the prediction of sudden cardiac death beyond traditional static ECG and clinical risk factors, introducing a novel marker for SCD risk assessment.
Pham et al. (2023) conducted a case-control in Sudden cardiac death (n=871). Dynamic ECG remodelling (cumulative six-variable ECG electrical risk score progression) vs. Baseline ECG and clinical risk factors was evaluated on Sudden cardiac death prediction (area under the receiver operating characteristic curve) (AUC, 95% CI 0.837-0.902). Dynamic ECG remodelling improved sudden cardiac death risk prediction beyond clinical factors and static ECG, increasing the area under the receiver operating characteristic curve from 0.770 to 0.869.
