Key result
Time-warping-based index predicts delayed VF risk earlier and more robustly than Tpe during porcine ischemia.
Why the study?
Does a time-warping-based index provide better prediction of ventricular fibrillation risk compared to the traditional Tpe index in a porcine myocardial infarction model?

A novel time-warping-based index provides earlier and more robust prediction of ventricular fibrillation risk than the traditional Tpe index in a preclinical myocardial infarction model.
The time-warping-based index, d^0.28436ptPCA_w, Tₚₑ, is a reliable non-invasive surrogate of DOR, with comparable predictive value for delayed VF risk under ischemic conditions, providing earlier and more robust prediction than the Tₚₑ index. These findings highlight their translational potential and require validation in human cohort studies.

Gómez et al. (2026) studied Myocardial Infarction. Time-warping-based index vs. Tpe index was evaluated on Delayed ventricular fibrillation risk. The time-warping-based index provided earlier and more robust prediction of delayed ventricular fibrillation risk under ischemic conditions than the Tpe index in a porcine model.
