Objective: To evaluate the factors responsible for the insufficient application of oral anticoagulation (OAC) in Chinese patients with non-valvular atrial fibrillation.
Methods: The research is a single center registration study in a tertiary referral hospital in Beijing. The general characteristics, history of atrial fibrillation, comorbidities and anticoagulation treatment were obtained from all patients.Factors affecting the oral Walfarin use were evaluated by univariable and multivariable regression analysis.
Results: OAC therapy with Walfarin was applied on Only 214(39.4%) out of 576 consecutive patients with non-valvular atrial fibrillation. The OAC rate was 30.3% among non-ablation patients. Patients with persistent atrial fibrillation, diabetes, chronic heart failure, history of ischemic stroke/TIA and higher CHA2DS2-VASc score were more likely prescribed with Walfarin. Multivariable regression analysis showed that persistent fibrillation, history of chronic heart failure, ischemic stroke/TIA and non-coronary heart disease predicted the treatment with Walfarin.
Conclusions: OAC use is extremely low in Chinese patients with non-valvular atrial fibrillation. More efforts are warranted to improve OAC use in these patients.

Background: Detection of atrial fibrillation (AF) in patients with embolic stroke of undetermined source (ESUS) is important for the secondary prevention of stroke. We investigated the factors associated with the detection of newly diagnosed AF in ESUS patients during follow-up.
Methods: Patients with acute ischemic stroke classified as ESUS were included.

Background: Apixaban and rivaroxaban are factor Xa inhibitors commonly used for treatment of venous thromboembolism and stroke prevention in patients with atrial fibrillation. While routine monitoring of their concentrations is not recommended, but it may be beneficial in certain situations. Expected peak and trough concentrations remain poorly understood, with most data derived from small studies OBJECTIVES: To establish the average peak and trough concentrations of apixaban and rivaroxaban from real-world studies.

Atrial fibrillation (AF), the most common type of heart arrhythmia, is recognized as an independent risk factor for stroke. Fortunately, catheter ablation (CA) offers an effective treatment option for AF patients. However, numerous studies have reported suboptimal outcomes, as AF recurrence rates often remain elevated even after CA.

Background: People with frailty have increased prevalence and incidence of atrial fibrillation (AF).
Objective: The study aimed to further investigate the association of long-term changes in frailty with risk of new-onset AF. Its associations with heart failure (HF), coronary heart disease (CHD), and stroke were also evaluated as a secondary aim.
