Atrial fibrillation (AF) is associated with activity of renin–angiotensin–aldosterone system (RAAS). Reduction in renal noradrenaline spillover could be achieved after renal sympathetic denervation (RSD). The relationship between RSD and AF is unknown. The objective of the study was to investigate the inducibility of AF during atrial rapid pacing after RSD.(More)
OBJECTIVE To determinate the prognostic value of etiology in patients with chronic systolic heart failure (CSHF). METHODS Data of in-hospital patients with CSHF were investigated between 2000 and 2010 from 12 hospitals in Hubei province. All patients were followed up through telephone calls. Univariate and multivariate Cox proportional hazards analyses(More)
BACKGROUND Studies have shown that increased levels of serum uric acid (SUA) are associated with atrial fibrillation (AF). However, less is known about the prognostic value of SUA levels for AF in patients with chronic heart failure (CHF). The aim of the study was to examine the prognostic value of SUA levels for AF in patients with CHF. METHODS Sixteen(More)
OBJECTIVE To evaluate the current status of chronic heart failure (CHF) in Hubei province and analyze the epidemiology of CHF including the general condition, etiology and pharmacological therapy. METHODS Data of in-hospital patients with CHF were investigated between 2000 and 2010 from 12 hospitals in Hubei Province. INCLUSION CRITERIA over 18 years of(More)
BACKGROUND The crista terminalis (CT) is known to initiate and maintain atrial arrhythmia, and is affected by autonomic tone, but the underlying mechanisms are poorly understood. This study sought to study the relation between autonomic innervation in CT and atrial arrhythmia. METHODS Thirty adult canines were used in the present study. Tissues of the CT(More)
AIMS The effects of ganglionated plexi (GP) ablation on atrial fibrillation (AF) inducibility and atrial autonomic innervation remodelling have not been elucidated. METHODS AND RESULTS Thirteen dogs were randomly divided into sham-operated group and GP ablation group. All animals underwent a right thoracotomy at the fourth intercostal space. Atrial(More)
BACKGROUND The chronic effects of ganglionic plexi (GP) ablation on atrial fibrillation (AF) inducibility have not been elucidated. OBJECTIVE To investigate the effect of Wenxin Keli (WK) on the inducibility of AF and atrial substrate remodelling after epicardial GP ablation. METHODS Twenty dogs were randomly divided into a sham-operated group, a GP(More)
The renin-angiotensin-aldosterone system is activated in pulmonary arterial hypertension (PAH) patients, and this activation may have long-term negative effects on the progression of PAH. The purpose of this study was to evaluate the effects of transcatheter renal sympathetic denervation (RSD) on the development of pulmonary arterial hypertension and(More)
OBJECTIVE To determinate the prognostic value of red cell distribution width (RDW) and the relationships between RDW and clinical characteristics in patients with chronic heart failure (CHF). METHODS A total of 16 681 in-hospital patients with chronic systolic HF and LVEF < 50% from 12 hospitals in Hubei province, China were enrolled. All patients were(More)
BACKGROUND There is mounting evidence to support the influence of inflammation and oxidative stress in the pathogenesis of atrial fibrillation (AF) and heart failure (HF). The efficacy of coenzymeQ10 (CoQ10), an antioxidant used as an adjunct treatment in patients with AF and HF, remains less well established. METHODS Consecutive patients with HF were(More)
