Post-mortem findings of cardiac lesions in epileptics: a preliminary report
Abstract:
In search of satisfactory cause of death in epileptics an attempt was made to examine the hearts with special regard to microscopic findings. All nine examined cases showed fibrosis of the minor arterial walls as well as interstitial fibrosis connected with atrophy or myofibrillar degeneration. Five cases had subendocardial fibrosis, and 4 leukocytic infiltration resembling focal myocarditis. In one case, a fibroma (hamartoma?) of the atrioventricular bundle could presumably explain the symptoms of epilepsy. The authors conclude that epilepsy may be a possible cause of ischemic or hypoxic cardiomyopathy which can contribute to the cause of sudden death amongst epileptics.
Insights
Sudden death in epilepsy may be linked to heart muscle damage. Microscopic heart changes, including fibrosis and inflammation, were found in nine epilepsy cases, suggesting a potential cause of death.
Area of Science:
- Cardiology
- Neurology
- Pathology
Background:
- Epilepsy is a neurological disorder associated with an increased risk of sudden death.
- The precise causes of sudden death in epilepsy (SUDEP) remain incompletely understood.
- Cardiac pathology is frequently investigated as a potential contributor to SUDEP.
Purpose of the Study:
- To investigate microscopic cardiac findings in individuals who died from epilepsy.
- To identify potential cardiac mechanisms contributing to sudden death in epileptic patients.
Main Methods:
- Post-mortem examination of heart tissue from nine epilepsy cases.
- Histopathological analysis focusing on myocardial and vascular changes.
- Evaluation for fibrosis, inflammation, and structural abnormalities.
Main Results:
- All nine cases exhibited fibrosis in small arterial walls and interstitial fibrosis with myocardial atrophy or degeneration.
- Subendocardial fibrosis was present in five cases.
- Leukocytic infiltration, suggestive of focal myocarditis, was observed in four cases.
- One case showed a fibroma (hamartoma?) of the atrioventricular bundle.
Conclusions:
- Epilepsy may lead to ischemic or hypoxic cardiomyopathy.
- These cardiac changes could be a significant factor in sudden death among individuals with epilepsy.
- Further research into cardiac involvement in SUDEP is warranted.
