Summary: Catheter ablation for atrial fibrillation was associated with microinfarctions in some patients immediately after the procedure, but showed a decrease in incidence after 6 months. Cognitive function also improved during the same period.

Summary: The study found that carotid stenosis was not associated with ischemic stroke, but was linked to thromboembolism. There was more consistent evidence suggesting that carotid plaque predicts stroke or transient ischemic attack in AF patients. Including carotid plaque and carotid intima-media thickness may improve stroke prediction and prevention in AF patients.

Summary: Through the research, it was found that there is a close association between Alzheimer's disease and cardiovascular disease, studying the combination of the two is a clinical challenge. Further research will help to reveal the real impact of cardiovascular disease and its risk factors on Alzheimer's disease, and better understand the effects of cardiovascular diseases on the brain.

Summary: A 63-year-old healthy male with atrial fibrillation presents with symptoms of dyspnea and irregular heartbeat. Physical examination reveals high blood pressure, irregular pulse, and ECG confirms atrial fibrillation. Further evaluation and treatment plan are needed.

Summary: Andrade et al. found that initial catheter cryoballoon ablation strategy resulted in lower incidence of persistent atrial fibrillation and lower arrhythmia burden compared to antiarrhythmic drug therapy in patients with paroxysmal atrial fibrillation during 3 years of follow-up. The study builds upon the findings of the EARLY-AF trial and the STOP AF First trial. Due to the relatively small sample size (303 patients) and short follow-up period, it may be difficult to detect mortality benefits of cryoballoon ablation.

Summary: This review summarizes the relationship between atrial fibrillation burden and adverse cardiovascular and cerebrovascular outcomes, and discusses the role of catheter ablation in mitigating the morbidity and mortality associated with a greater burden of atrial fibrillation.

Summary: Patients with atrial fibrillation (AF) have a higher risk of cognitive decline, especially poststroke AF patients who face a threefold increased risk. The association between AF and cognitive decline is not solely due to previous ischemic strokes, as recent evidence suggests such an association even in AF patients without a history of clinical stroke. Silent brain infarcts and other brain injuries are potential mechanisms for the increased risk of cognitive decline among AF patients. Oral anticoagulation for stroke prevention in AF patients is a proven therapy to prevent brain injury, but the broader use and intensity of anticoagulation need to be further studied. Optimal treatment of comorbidities and risk factors is also recommended for the prevention of cognitive decline and dementia.

Summary: This study aimed to estimate the risk of atrial fibrillation (AF) recurrence in patients with new-onset AF during a hospitalization for noncardiac surgery or medical illness compared to a matched population without AF.

Summary: Cardiovascular risk factors and left atrial disease increase the risk of developing atrial fibrillation in patients. N-terminal pro-B-type natriuretic peptide and premature atrial contractions can independently predict the risk of atrial fibrillation-free survival. However, the role of excessive supraventricular ectopic activity in assessing atrial fibrillation risk may be underestimated.

Summary: This study suggests that atrial fibrillation is associated with a increased risk of dementia, particularly in younger patients and those without chronic kidney disease, but does not vary significantly by sex, race, or ethnicity.

Summary: This pioneer study investigated the impact of pre-existing left atrial appendage occluder (LAAO) on atrial fibrillation (AF) substrates and outcomes of pulmonary vein isolation (PVI). Results showed that LAAO may modulate left atrial substrate and induce peridevice fibrosis, peridevice left atrial flutter, and complex fractionate atrial electrogram.

Summary: This study examined the association between catheter ablation and incident dementia and mortality in patients with atrial fibrillation (AF). The results showed that catheter ablation was associated with a lower risk of dementia and mortality, highlighting its importance in patient-centered rhythm control strategies.

Summary: Atrial fibrillation catheter ablation significantly reduces the risk of ischemic stroke and intracranial hemorrhage in patients with AF, compared to medical therapy, to the extent of the non-AF population. Post-procedural AF control influences the risk of ischemic strokes.

Summary: This study aimed to investigate the prevalence and electrophysiological characteristics of atrial fibrillation (AF) drivers arising from the right atrial appendage (RAA). The results showed that 7% of patients had RAA drivers, which were associated with the termination of AF.
