Study is latest in a series to suggest similar findings

LONDON--(BUSINESS WIRE)--Oct. 23, 2019-- LivaNova PLC (NASDAQ:LIVN), a market-leading medical technology and innovation company, today announced the publication of a new study in Neurology, which suggests that chronic epilepsy may be associated with key measures of sudden cardiac death risk.¹ This is the third in a series of studies^1-3 to evaluate cardiac electrical instability in patients with chronic epilepsy but the first to compare the cardiac impact of the disease among patients with chronic epilepsy to those who are newly diagnosed.

The study in Neurology evaluated established markers of sudden cardiac death risk, T-wave alternans (TWA) and heart rate variability (HRV), in patients with chronic epilepsy compared to patients with newly diagnosed epilepsy. Using data recorded on ambulatory electrocardiographic monitors, the investigators assessed whether cardiac electrical instability indicated by TWA and abnormal autonomic tone measured by HRV result from recurrent seizures. Results from the analysis showed that chronic epilepsy is associated with higher TWA levels and simultaneously with lower HRV, suggesting autonomic dysfunction or higher sympathetic tone.

“This study provides evidence indicating that, over time, some people with epilepsy may become predisposed to potentially serious heart rhythm abnormalities, due either to the effect of recurrent seizures, antiepileptic medications or other influences on the heart,” said Dr. Trudy Pang, lead study author and Assistant Professor of Neurology at Harvard Medical School. “Further work is needed to understand better the risks and the cause(s), so that we can develop more effective treatment options.”

Two previous studies in this series have shown that vagus nerve stimulation was associated with improvement in HRV and cardiac vagal tone and reduction in TWA in patients with epilepsy,^2,3 making it a potential treatment for further study.

“This latest study published in Neurology further contributes to our understanding of the risk factors for sudden cardiac death in patients with epilepsy.⁴ The prior two studies in the series^2,3 evaluated the potential for Vagus Nerve Stimulation Therapy^® or VNS Therapy to reduce T-wave alternans, a well-established marker of cardiac electrical instability, in patients with drug-resistant epilepsy,” said Bryan Olin, study co-author and Senior Vice President of Clinical, Quality and Regulatory Affairs at LivaNova. “The clinical impact of this effect in terms of reducing the rate of sudden cardiac death in patients with epilepsy remains to be studied. However, results from this study may also guide development of medical therapy for both seizure reduction and cardiac protection in patients with epilepsy.”

The LivaNova VNS Therapy System is clinically proven safe and effective for the treatment of drug-resistant epilepsy for adults and children.

About VNS Therapy^® for Epilepsy

VNS Therapy is clinically proven safe and effective for the treatment of drug-resistant epilepsy for adults and children 4 years of age and older. VNS Therapy is designed to prevent seizures before they occur and stop them if they do. It is a unique treatment approach developed for people with drug-resistant epilepsy—a condition that affects one in three people with epilepsy. For more information, visit VNSTherapy.com.

INTENDED USE / INDICATIONS – UNITED STATES

Epilepsy—The VNS Therapy System is indicated for use as an adjunctive therapy in reducing the frequency of seizures in patients 4 years of age and older with partial onset seizures that are refractory to antiepileptic medications.

Commonly reported side effects are hoarseness, shortness of breath, sore throat and coughing. Side effects typically occur during stimulation and decrease over time.
