Chronic heart failure involves autonomic imbalance, with reduced parasympathetic activity worsening outcomes. This review explores neuromodulation strategies targeting the vagus nerve for heart failure treatment.
Area of Science:
- Cardiology
- Neuroscience
- Physiology
Background:
- Autonomic imbalance, characterized by increased sympathetic and reduced parasympathetic nerve activity, is linked to chronic heart failure progression and adverse outcomes.
- Reduced heart rate variability and baroreflex sensitivity indicate vagal dysfunction and hold prognostic value in heart failure patients, even with contemporary treatments.
Purpose of the Study:
- To review the role of the parasympathetic nervous system in chronic heart failure.
- To describe the pathophysiological basis, assessment methods, and therapeutic strategies for parasympathetic stimulation in heart failure.
Main Methods:
- Literature review of studies on parasympathetic nervous system function in chronic heart failure.
- Analysis of current and emerging neuromodulation strategies, including pharmacological and bioelectronic approaches.
Main Results:
- Parasympathetic dysfunction is a significant factor in chronic heart failure pathophysiology and prognosis.
- Current neuromodulation strategies targeting the vagus nerve have shown mixed results, necessitating further research.
Conclusions:
- Parasympathetic stimulation presents a potential therapeutic avenue for chronic heart failure.
- Further investigation into drug-based and device-based vagal nerve stimulation is crucial to optimize treatment efficacy and patient outcomes.
