Risk Prediction Model for SCD(National Institute of Health Carlos III, Research Project 17/01327)
1. Merging SCD with episodes of life-threatening
ventricular arrhythmias into a composite end-point.
2. Incorporating the baseline lesion-specific risk
stratification.
3. Including easily available demographic, clinical,
ECG, and echo variables
