Subclinical cardiac dysfunction detected by speckle-tracking echocardiography in children with drug-resistant epilepsy

Compares cardiac function in pediatric drug-resistant epilepsy (DRE) and drug-responsive epilepsy, identifying impaired systolic function and global longitudinal strain (GLS) in DRE. Correlates GLS abnormalities with antiseizure medication burden and time since last seizure, linking cardiac dysfunction to treatment intensity and epilepsy disease course. Advocates STE for early cardiac monitoring in DRE and urges longitudinal studies to disentangle epilepsy-related cardiovascular risks from drug-driven effects.
