Purpose of review The association between atrial fibrillation and stroke is firmly established, and anticoagulation reduces stroke risk in patients with atrial fibrillation. However, the role of anticoagulation in very brief durations of atrial fibrillation (subclinical atrial fibrillation) is an area of controversy. Recent findings Stroke risk increases alongside burden of atrial fibrillation. Ongoing trials will clarify if 24 h or less of atrial fibrillation on extended monitoring necessitates lifelong anticoagulation. Trials examining empiric anticoagulation for individuals with ESUS did not demonstrate benefit o...

Background Atrial fibrillation is common in the setting of acute coronary syndromes (ACS) although its impact on ACS remains controversial. Aim To describe in-hospital management of patients with atrial fibrillation and ACS evaluating the impact of atrial fibrillation on in-hospital and mid-term outcome. Methods We analysed the data of two prospective multicentre nationwide registries (IN-ACS Outcome and MANTRA) to assess clinical characteristics, management, and outcomes of patients with ACS and atrial fibrillation. Study outcomes included death from any cause and a composite end-point of death/re-infarction/strok...

Conclusion Pooled analysis suggest that patients with atrial fibrillation may be exposed to an increased risk of developing new onset of Alzheimer's disease. Given the relevant clinical implications, further studies are required to corroborate these findings.

ConclusionsNon ‐inducibility of atrial arrhythmia or change in inducibility status following PV isolation and substrate modification are not associated with long‐term freedom from recurrent arrhythmia. Therefore, the use of induction of an endpoint in AF‐ablation is limited.This article is protected by copyright. All rights reserved.

Abstract Atrial fibrillation (AF) is the most common type of arrhythmia, which undermines cardiac function. Atrial fibrillation is a multi-facet malady and it may occur as a result of other diseases or it may trigger other problems. One of the main complications of AF is stroke due to the possibility of clot formation inside the atrium. However, the possibility of stroke occurrence due to the AF and the location from which an embolus dispatches are subject of debate. Another hypothesis about the embolus formation during AF is thrombus formation in aorta and carotid arteries, embolus detachment and its movement. To...

This study is divided into two stages: (a) a systematic review carried out following the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA) statement in six databases, in order to identify the features of the PPG signal reported in the literature for the detection of AF, and (b) an experimental evaluation of them, using machine learning, in order to determine which have the greatest influence on the process of detecting AF. Forty-four features were found when analyzing the signal in the time, frequency, or time–frequency domains. From those 44 feat...

We examined frequency, clinical characteristics and AF‐related management and outcomes amongst this patient population.MethodsWe retrospectively studied consecutive probands with inherited cardiomyopathy (n=962) and inherited arrhythmia syndromes (n=195) evaluated between 2002 ‐2018.ResultsAF was observed in 5 ‐31% of patients, with the highest frequency in HCM. Age of AF onset was 45.8 ± 21.9 years in the inherited arrhythmia syndromes compared to 53.3 ± 15.3 years in the inherited cardiomyopathies, with 4 CPVT patients developing AF at median age of 20 years. Overall, 11% of patients with AF had a t r...

We examined the diagnostic utility of an ILR in detecting arrhythmic causes of US and determining which clinical factors are associated with pacemaker (PM) implantation. METHODS: This retrospective, multicenter, observational study was conducted from February 2006 to April 2018 at 11 hospitals in Korea. Eligible patients with recurrent US received an ILR to diagnose recurrent syncope and document arrhythmia. RESULTS: A total of 173 US patients (mean age, 67.6 ± 16.5 years; 107 men [61.8%]) who received an ILR after a negative conventional workup were enrolled. During a mean follow-up of 9.4 ± 11.1 m...

Conclusion: These results provided compelling evidence that primary aldosteronism is highly prevalent in hypertensive patients with unexplained atrial fibrillation. Accordingly, they suggest that patients with no identifiable cause of the arrhythmia should be screened for primary aldosteronism to identify those who can be cured or markedly improved with target treatment. Clinical Trial Registration: : https://clinicaltrials.gov, Identifier: NCT01267747.
