Nerve stimulation techniques
View Patent ↗A method is provided for treating heart failure in a subject in need of such treatment, including applying a stimulating current to parasympathetic nervous tissue of the subject, selected from the group consisting of: a vagus nerve and an epicardial fat pad. The stimulating current is configured to inhibit release of at least one proinflammatory cytokine sufficiently to the treat heart failure of the subject. A level of the at least one proinflammatory cytokine is measured. Optionally, the stimulating current is configured to change a level of Connexin 43 of the subject, and the level of Connexin 43 is also measured. Other embodiments are also described.
1. A method for treating heart failure in a subject in need of such treatment, comprising:
applying a stimulating current to parasympathetic nervous tissue of the subject, selected from the group consisting of: a vagus nerve and an epicardial fat pad;
configuring the stimulating current to inhibit release of TNF-alpha, IL-6, Activin-A, and TGF-beta sufficiently to the treat heart failure of the subject; and
measuring a level of TNF-alpha, IL-6, Activin-A, and TGF-beta.
2. The method according to claim 1 , wherein the configuring comprises configuring the stimulating current to inhibit the release of TNF-alpha, IL-6, Activin-A, and TGF-beta and to change a level of Connexin 43 of the subject, and wherein measuring comprises measuring the level of TNF-alpha, IL-6, Activin-A, and TGF-beta and the level of Connexin 43.
3. The method according to claim 1 , wherein the heart failure is selected from the group consisting of: heart failure, congestive heart failure, and diastolic heart failure.
4. The method according to claim 1 , wherein applying the stimulating current comprises applying the stimulating current during a period having a duration of at least one week.
5. The method according to claim 1 , wherein measuring the level of TNF-alpha, IL-6, Activin-A, and TGF-beta comprises measuring a level of mRNA expression of TNF-alpha, IL-6, Activin-A, and TGF-beta.
