Summary

To verify the efficacy of transcutaneous vagus nerve stimulation (tVNS) on and autonomic balance in patients with chronic heart failure and reduced (HFrEF) or mildly reduced (HFmrEF) left ventricular ejection fraction. The study hypothesis is that tVNS increases baroreflex gain, with consequent benefits on sympathovagal balance (at short- and mid-term), and on quality of life and bio-humoral parameters (at mid-term).

Conditions

  • Heart Failure
  • Heart Failure With Reduced Ejection Fraction
  • Heart Failure With Midrange Ejection Fraction

Interventions

DEVICE

Active tVNS

As for the short-term phase, the ear clip of the "Parasym" device (Parasym, London, United Kingdom), containing the stimulation electrode, will be positioned at the level of the patient's tragus, and a 10-minute stimulation will be initiated with a pulse width of 200 μs, a frequency of 30 Hz, and an intensity of one mA lower than the patient's sensitivity threshold. As fort he mid-term phase, a device will be given to the patient, which will be instructed to position the ear clip of the device at the level of the tragus and to set stimulation parameters as established in the laboratory (see above). Each patient will be asked to undergo at least one hour daily stimulation for a period of 4 weeks, reporting on a diary the timing and details of the each session.

DEVICE

Sham tVNS

As for the short-term phase, the ear clip of the "Parasym" device (Parasym, London, United Kingdom), containing the stimulation electrode, will be positioned at the level of the patient's tragus for 10-minute but no current will be delivered. As fort he mid-term phase, a device (configured to withhold power delivery) will be given to the patient, which will be instructed to position the ear clip of the device at the level of the tragus and to set stimulation parameters as established in the laboratory (see above). Each patient will be asked to undergo at least one hour daily stimulation for a period of 4 weeks, reporting on a diary the timing and details of the each session.
