title: Atrial ganglionated plexi stimulation may be an effective therapeutic tool for the treatment of heart failure.
abstract: An autonomic imbalance, i.e., increased sympathetic tone and/or decreased parasympathetic tone is a critical characteristic of heart failure, which is associated with progressive ventricular remodeling, ventricular arrhythmia generation and disease progression. Increasing cardiac parasympathetic tone by vagus nerve stimulation has been shown to significantly improve heart failure symptoms, hemodynamics, left ventricular function and quality of life. However, cervical surgery is needed to position vagal stimulation electrode and vagus nerve stimulation may also cause some undesired side effects. Our recent studies showed that ablation of the main atrial ganglionated plexi (GP) facilitated the occurrence of ventricular arrhythmias in acute myocardial ischemic heart while low-intensity atrial GP stimulation inhibited the occurrence of ventricular arrhythmias during acute myocardial ischemia and ischemia reperfusion. Based on these results, we hypothesize that atrial GP stimulation may ameliorate autonomic dysfunction in heart failure, inhibit heart failure progression and improve heart failure prognosis.
