Abstract:Atrial fibrillation (AF) is the most common atrial arrhythmia in adults worldwide. As medical advancements continue to contribute to an ever-increasing aging population, the burden of atrial fibrillation on the modern health care system continues to increase. Therapies are also evolving, for treatment of the arrhythmia itself, and stroke risk mitigation. Internists and cardiologists alike are, in most instances, the frontline contact for AF patients, and would benefit from remaining facile in their understandi… Show more

“…In clinical practice, atrial fibrillation (AF) is a common heart arrhythmia associated with an elevated risk of adverse effects, such as thromboembolic strokes, heart failure (HF), systemic embolism (SE), and all-cause mortality (1,2). It is estimated that 33.5 million individuals worldwide are affected with AF (3), and its prevalence is projected to increase in the coming years (4).…”

“…[ 2 – 4 ] Until 2016, there were more than 33.5 million AF patients worldwide, with a population incidence of 2.5% to 3.5%. [ 5 ] The main complications of AF include stroke, thromboembolism, myocardial infarction, heart failure, cognitive decline, dementia, and renal impairment, and the main treatment are ventricular rate control, rhythm control, and anticoagulant therapy, which are supported by the American Heart Association, [ 6 ] European Society of Cardiology, [ 4 ] and Canadian Cardiovascular Society. [ 7 ] Rhythm control as a primary therapy can reduce the risk of thromboembolism and the usage of anticoagulant drugs, and improve the left ventricular function, the hemodynamics, patient symptoms, and their quality of life.…”
Background:
The high recurrence rate of atrial fibrillation (AF) after recovering sinus rhythm has always been a clinical problem. Despite the established and widespread use of antiarrhythmic drugs, which one is better for maintaining sinus rhythm is still controversial. This study aims to summarize the randomized controlled trials (RCTs) of amiodarone combined with beta blockers to maintain sinus rhythm in AF, and to determine an effective and safe intervention for the prevention of AF recurrence through network meta-analysis (NMA).
Methods and analysis:
A comprehensive search of the RCTs comparing amiodarone with different beta-blockers to maintain sinus rhythm of AF patients will be conducted from the inception to December 2019 in the Cochrane Library, PubMed, Web of Science, EMBASE, Chinese Biomedical Literature Database (SinoMed), Chinese National Knowledge Infrastructure (CNKI), and WanFang database. The primary outcomes will be the recurrence of AF and frequency of embolization complications. The secondary outcomes will be the symptom improvements and adverse events. Risk of bias assessment of the included RCTs will be conducted according to the Cochrane collaboration's risk of bias tool. Pairwise meta-analyses and Bayesian network meta-analyses will be performed for all related outcome measures. GRADE will be used to evaluate the quality of evidence.
Results:
The results of this NMA will be published in a peer-reviewed journal.
Conclusion:
This NMA may provide more recommendations for patients and researchers, such as which treatment is better for a particular case of AF, and what may be the hotspots for the future studies.
PROSPERO registration number:
The protocol for this NMA has been registered on PROSPERO under the number CRD42020164438.
“…Atrial brillation (AF), a frequent type of supraventricular arrhythmia, is the most common atrial arrhythmia among adults worldwide, and its prevalence has been increasing (1). AF is a progressive disease, and its early stage is paroxysmal AF (pAF); more than 50% of the pAF patients progress to persistent AF or die within 10 years (2).…”
Background: To evaluate the clinical efficacy of serum high-mobility group box-1 (HMGB1) released from the left atrium to predict atrial fibrillation (AF) recurrence in paroxysmal AF (pAF) patients after catheter ablation (CA) at 1-year follow-up.Methods: We included 72 pAF patients who underwent CA. To determine the expression levels of HMGB1, left atrial blood samples were collected from the patients prior to CA and after the procedure through the transseptal sheath placed into the left atrium. Patients were followed-up for AF recurrence after 1 year of CA.Results: A total of 19 (26%) patients of the 72 experienced AF recurrence. No significant differences were noted in the clinical baseline data between the AF recurrence and AF nonrecurrence groups. The level of postoperative HMGB1 (HMGB1post) was higher in the AF recurrence group than in the AF nonrecurrence group (298.51µg/L vs. 278.17 µg/L; P = 0.03). However, no differences were noted in the levels of other biomarkers such as preoperative high-sensitivity C-reactive protein (hs-CRPpre), postoperative hs-CRP (hs-CRPpost), and preoperative HMGB1 (HMGB1pre) between the two groups. Multiple logistic regression analysis revealed that a higher level of serum HMGB1post from the left atrium (HMGB1post: ≥279.35 µg/L) was an independent predictor of AF recurrence (odds ratio [OR]: 5.29 [1.17–23.92], P = 0.04). Receiver operating characteristic (ROC) analysis revealed that HMGB1post had a moderate predictive power for AF recurrence (area under the curve [AUC]: 0.68; sensitivity: 72%; specificity: 68%). The 1-year AF-free survival was significantly lower in patients with a high serum HMGB1post level than in those with a low HMGB1post level (hazard ratio [HR]: 3.81 [1.49–9.75], P = 0.005). Conclusion: In pAF patients who underwent CA, the level of HMGB1 from the left atrium immediately after CA was associated with AF recurrence and demonstrated a moderate predictive power. Thus, we offer a potential predictor to identify pAF patients at high risk of AF recurrence.
