Epilepsy and cardiovascular disease intersect through shared risk factors, seizure-related autonomic effects, medication interactions and the vascular causes of late-onset epilepsy.
Population studies show an association
A 2024 meta-analysis of more than seven million participants found higher cardiovascular mortality and stroke risk in people with epilepsy.
Observational associations do not prove that epilepsy itself directly causes all of this excess risk.
Stroke links the two conditions strongly
Stroke is a major cause of new-onset epilepsy in later life.
Once epilepsy is present, vascular risk factors still need ordinary prevention rather than being overshadowed by seizure care.
Seizures affect the heart acutely
Tachycardia is common during seizures, while bradyarrhythmias and asystole are much rarer.
These acute ictal effects are distinct from chronic cardiovascular disease.
Medication choice can matter
Older enzyme-inducing antiseizure medicines can interact with cardiovascular drugs and may affect lipid metabolism.
Polypharmacy therefore deserves active review.
Routine cardiovascular care still matters
Blood pressure, lipids, diabetes, smoking, physical activity and sleep-disordered breathing remain relevant.
Epilepsy should not result in under-treatment of conventional cardiovascular risk factors.
