An analysis of the biomolecule substudy of the EAST–AFNET 4 trial has revealed that biomolecule concentrations in the blood of patients with atrialfibrillation can be used to identify patients at high and low cardiovascular risk. The findings were published in Cardiovascular Research.
Background We evaluated the potential of circulating bone morphogenetic protein 10 (BMP10) as a biomarker for atrial stress and remodelling in patients with heart failure (HF), in comparison to N-terminal pro-B-type natriuretic peptide (NT-proBNP). We also assessed the predictive value of BMP10 for adverse clinical outcomes.
Circulation. Outcomes of ablation with the FARAPULSE PFA System – a nonthermal treatment in which electric fields selectively ablate heart tissue – will be compared to outcomes following use of anti-arrhythmic drug (AAD) therapy, which is commonly prescribed for patients living with persistent AF.
When atrialfibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. A fibrillatory wave that occurs at a rate of more than 600 beats per minute can cause fatigue in the long run, leading to atrial dilation.
The increasing prevalence of atrialfibrillation (AF) in adults with congenital heart disease raises significant questions regarding its management. Journal of the American Heart Association, Ahead of Print. Finally, any remaining gaps in knowledge and potential areas of future research are highlighted.
Circulation, Ahead of Print. Recommendations from the “2014 AHA/ACC/HRS Guideline for the Management of Patients With AtrialFibrillation” and the “2019 AHA/ACC/HRS Focused Update of the 2014 AHA/ACC/HRS Guideline for the Management of Patients With AtrialFibrillation” have been updated with new evidence to guide clinicians.
Background Covert atrialfibrillation (AF) is a predominant aetiology of embolic stroke of undetermined source (ESUS). Conclusion Our study showed that posterior circulation infarcts with brainstem/cerebellum involvement are associated with AF detection in ESUS patients undergoing ILR.
A JACC study suggests that atrialfibrillation is far more prevalent than many previously thought, estimating that nearly one in 20 American adults have been diagnosed with the disease. That’s far higher than previous estimates, including a pair of JAMA and Circulation studies that estimated nationwide AFib rates of 2.26M and 5.1M
Metabolic remodeling has been recently pointed to play an important role in the pathological process of atrialfibrillation (AF). Ketone bodies (KB) are important cardiac metabolic energy source.
Patients who present with persistent atrialfibrillation at diagnosis are more likely to have certain risk factors as compared with patients with occasional atrialfibrillation (AFib).
Titled "Real-world Data Affirms Safety and Effectiveness of Low/Zero Fluoroscopy AtrialFibrillation Ablation," the study was presented as a late-breaker at the 29th Annual International AF Symposium. Real-world Data Affirms Safety and Effectiveness of Low/Zero Fluoroscopy AtrialFibrillation Ablation [abstract].
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Atrial fibrillation is the most common cardiac arrhythmia in the world and increases the risk for stroke and morbidity. This finding could have important ramifications for identifying clinically important forms of atrialfibrillation and in guiding treatment.
We aimed to synthesise existing evidence on the observational and genetic associations between circulating proteins and CMD. Two investigators independently extracted study characteristics using a standard form and pooled data using random effects models.
Objectives In dyspneic patients with atrialfibrillation (AF) or obesity, the diagnostic performance of NT-proBNP for acute heart failure is reduced. In patients with AF, the AUC decreased for ERFE in each cohort (NZ: 0.71, n = 105, SG: 0.61, n = 44) but increased in patients with obesity (NZ: 0.79, n = 150, SG: 0.87, n = 164).
Torsade de pointes (TdP) was not a rare arrhythmia in Israel during the 1970s–1980s as many patients, mainly with atrialfibrillation (AF), were treated with QT-prolonging antiarrhythmic drugs. Our experience was published in 1981 in Circulation.1
Circulation: Cardiovascular Imaging, Ahead of Print. BACKGROUND:Patients with only moderate atrial secondary mitral regurgitation (asMR) frequently develop heart failure (HF). Mechanisms of HF with moderate asMR and the impact of mild asMR remain unclarified.
Her Apple Watch suddenly told her that she is in atrialfibrillation. Patients with healthy AV nodes who are not on AV nodal blockers and who are not hyperkalemic should have a rapid ventricular response if they have paroxysmal Atrialfibrillation. Exam was completely normal except for an irregular heart rate.

Circulation, Volume 150, Issue Suppl_1 , Page A4141066-A4141066, November 12, 2024. Background:Clinical studies on atrialfibrillation (AF) recurrence after catheter ablation in patients diagnosed with patent foramen ovale (PFO) and paroxysmal AF (PAF) are scarce.
Circulation, Volume 150, Issue Suppl_1 , Page A4139226-A4139226, November 12, 2024. Background:Anticoagulation is the standard treatment for the majority of patients with atrialfibrillation (AF) to reduce the risk of stroke. Such patients are at high risk for bleeding and stroke.
Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:The strongest genetic risk factors for atrialfibrillation (AF) are DNA variants on chromosome 4q25 near the transcription factor genePITX2.
Circulation, Volume 150, Issue Suppl_1 , Page A4135095-A4135095, November 12, 2024. Background:While anticoagulation is crucial for atrialfibrillation (AF) patients to prevent ischemic events, those with thrombocytopenia have a potential increased risk of bleeding.
Circulation, Ahead of Print. BACKGROUND:The relationship between heart failure (HF) and atrialfibrillation (AF) is clear, with up to half of patients with HF progressing to AF. The pathophysiological basis of AF in the context of HF is presumed to result from atrial remodeling.
