Abstract
OBJECTIVES Autonomic nervous activity imbalance plays an important role in atrial fibrillation (AF). AF can be treated by acupuncture at the Neiguan point (PC6), but the mechanism remains elusive. Here, we investigated autonomic nervous system activity in electroacupuncture (EA) at PC6 in a rat AF model. MATERIAL AND METHODS In this study, we established a rat AF model via tail vein injection with ACh-CaCl2 for ten consecutive days with or without EA at PC6. AF inducibility and heart rate variability (HRV) were assessed by electrocardiogram. Next, we completed in vivo recording of the activity of cervical sympathetic and vagal nerves, respectively. Finally, the activities of brain regions related to autonomic nerve regulation were assessed by c-Fos immunofluorescence and multichannel recording. RESULTS EA at PC6 decreased AF inducibility and prevented changes in HRV caused by ACh-CaCl2 injection. Meanwhile, EA at PC6 reversed the increased sympathetic and decreased vagal nerve activity in AF rats. Furthermore, EA treatment downregulated increased c-Fos expression in brain regions, including paraventricular nucleus, rostral ventrolateral medulla, and dorsal motor nucleus of the vagus in AF, while c-Fos expression in nucleus ambiguus was upregulated with EA. CONCLUSION The protective effect of EA at PC6 on AF is associated with balance between sympathetic and vagal nerve activities.

[PMID: 33817773 DOI: 10.1007/s11897-021-00508-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/16/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE OF REVIEW Catheter ablation of atrial fibrillation in heart failure seems to be the way to improve the quality of life, life expectance, and prognosis. In this review, we outline the growing role of this therapy and which patients can benefit from it. RECENT FINDINGS While previous studies comparing rate control and rhythm control had not demonstrated the superiority of rhythm control in the prognosis of patients with atrial fibrillation and heart failure, recent findings seem to demonstrate that catheter ablation of atrial fibrillation reduces mortality and hospitalization for heart failure and improves the quality of life, when compared to medical therapy alone. An early rhythm-control strategy in atrial fibrillation may reduce cardiovascular death, stroke, hospitalization for HF, or acute coronary syndrome. Catheter ablation in heart failure is an effective and safe solution to obtain a rhythm control and, therefore, to improve outcomes. A better selection of the patients could help to avoid futile procedures and to identify patients requiring a closer follow-up, to redo procedures, or the addition of antiarrhythmic drugs.

J Affect Disord 2020; 271:27-32. [PMID: 32312694 DOI: 10.1016/j.jad.2020.03.118] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 02/05/2020] [Accepted: 03/29/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND The influence of depression on the recurrence of atrial fibrillation (AF) after catheter ablation remains unclear. We performed a meta-analysis to evaluate the association between depression and AF recurrence after catheter ablation. METHODS Cohort studies that evaluated depression at baseline and correlated depression with AF recurrence after catheter ablation were identified by searching the PubMed and Embase databases. Heterogeneity was determined using the Cochrane's Q test and calculating the I2 statistic. A random-effect model was applied to incorporate the potential influence of heterogeneity. RESULTS Our analysis included seven cohort studies with 1,070 AF patients who underwent catheter ablation by circumferential pulmonary vein isolation. No significant heterogeneity was detected among the included studies (p for Cochrane's Q test = 0.20, I2 = 29%). Pooled results showed that depression before procedure was independently associated with increased risk of AF recurrence after catheter ablation (adjusted relative risk [RR]: 2.24, 95% confidence interval [CI]: 1.75 - 2.88, p < 0.001). Sensitivity analyses, conducted by omitting one study at a time, retrieved similar results (RR: 2.06 - 2.53, p all < 0.05). Predefined subgroup analyses showed that the association between depression and AF recurrence after catheter ablation was consistent regardless of the study characteristics, including study location, study design, patient number, type of AF, follow-up duration, adjustment of left atrial dimension, and quality score. LIMITATIONS This analysis included a limited number of studies and various instruments applied to measure depression. CONCLUSIONS Depression is an independent risk factor of AF recurrence after catheter ablation.
