Subclinical Atrial Fibrillation Preceding Cardioembolic Stroke in a Patient with Systolic Heart Failure
Atrial fibrillation and congestive heart failure are risk factors for cerebral infarction. The most commonly used estimates of stroke risk in patients with atrial fibrillation are cardiac failure, hypertension, age, diabetes mellitus, and stroke (CHADS2 score) [1–4]. Although atrial fibrillation may be recognized by the presence of symptoms, such as palpitations, some patients are occasionally asymptomatic [5–7]. The absence of symptoms results in a delayed diagnosis, and may lead to fatal thromboembolic events.

Obstructive sleep apnea and the risk of ischemic stroke in patients with atrial fibrillation
Atrial fibrillation (AF) is associated with significant morbidity and mortality. Prevention of thromboembolism with oral anticoagulant agents is an important treatment for patients with AF. CHADS2 and CHA2DS2-VASc score has been widely used as the initial approach to assess future stroke risk among AF patients. Obstructive sleep apnea (OSA) is a common breathing disorder associated with substantial cardiovascular morbidity and mortality. It has been reported as an independent risk factor for ischemic stroke [1–4].

Obstructive Sleep Apnea and Stroke Risk in Atrial Fibrillation: Is There A Correlation or Not?
We have read with great interest the article recently published by Chin Chang et al. entitled “Obstructive sleep apnea and the risk of ischemic stroke in patients with atrial fibrillation” [1]. However, we have some concerns about article. Our first concern is about CHA2DS2-VASc scores of the study groups. The CHA2DS2-VASc score evaluates factors such as vascular disease, hypertension, and diabetes as contributors to stroke risk. Although subjects with concomitant atrial fibrillation (AF) and obstructive sleep apnea (OSA) had a higher percentage of hypertension, diabetes, coronary artery disease, and peripheral arteria...

Is obstructive sleep apnea associated with the risk of ischemic stroke in patients with atrial fibrillation?
Atrial fibrillation (AF) is one of the most important preventable causes of ischemic stroke. Current guidelines recommend assessing the thromboembolic risk by either CHADS2 or CHA2DS2-VASc scores [1]. Unfortunately, both scores base only on age and previously diagnosed comorbidities, and tend to omit many important aspects that strongly influence patients’ risk and prognosis. Factors such as left atrial morphology and function or chronic kidney disease were previously shown to be associated with higher risk of stroke and influence the necessity of anticoagulation in atrial fibrillation patients [2,3].

Management of stroke prevention in bulgarian patients With non-valvular atrial fibrillation (bul-af survey)
It is well known the patients with atrial fibrillation (AF) have a 5-fold increased risk of stroke compared to those without AF. Moreover, the incidence of ischemic stroke in asymptomatic or recurrent paroxysmal AF is comparable to this one in chronic AF. In this setting, the knowledge of the physicians about the anticoagulation therapy in AF is essential to reduce the AF complications and to improve the quality of patients` life. (See Figs. 1 and 2.)

Reasons for non-adherence to practice guidelines on stroke prevention in patients with atrial fibrillation: A cross-sectional study in primary care
Atrial fibrillation (AF) is associated with an increased risk of stroke and mortality if left untreated [1]. Anticoagulants – such as vitamin K antagonists (VKA) and non-VKA oral anticoagulants (NOACs) – are highly effective in preventing this [2], but inherently carry the risk of bleeding complications. To identify AF patients in whom stroke risk outweighs bleeding risk, practice guidelines recommend to use clinical decision rules. However, adherence to such guidelines is low [3]. Knowledge of the exact reasons for this non-adherence is scarce and mainly based on vignette studies or qualitative studies in which physic...

New-onset atrial fibrillation in patients with elevated troponin I levels in the acute phase of stroke
Troponin I (TnI) increase in the acute phase of stroke may be due to the presence of acute coronary syndrome (ACS), other medical conditions and/or neurogenic-induced cardiac injury, especially in stroke involving the insula of the right brain hemisphere [1]. In this case, damage to cardiomyocytes is probably due to the rapid release of catecholamines into the bloodstream as a result of sympathoadrenal activation [2,3]. The consequences of cardiac injury may include new-onset arrhythmias, such as multifocal ventricular beats, couplets and unsustained ventricular tachycardia or atrial fibrillation (AF) [3].

Predictors of new onset atrial fibrillation during 10-year follow-up after first-ever ischemic stroke
: Paroxysmal atrial fibrillation (AF) may be underdiagnosed in ischemic stroke patients but may be pivotal for initiation of oral anticoagulation therapy. We assessed clinical and ECG predictors of new-onset AF during 10-year follow-up (FU) in ischemic stroke patients.

Left atrial appendage occlusion in atrial fibrillation for stroke prevention: A Systemic Review
Atrial fibrillation (AF) is an arrthymias characterized by increased risk of ventricle arrthymias and thromboembolism especially ischemic stroke. Most thrombus originated in left atrial appendage, thus left atrial occlusion (LAAO) may be an effective alternative for stroke prevention in atrial fibrillation.

Fatal stroke following treatment with apixaban in a patient with atrial fibrillation and left atrial appendage thrombus
Atrial fibrillation increases the risk of ischemic stroke 4–5 fold [1] and doubles the mortality independently of other vascular risk factors [2]. The vast majority (>90%) of thrombi associated with atrial fibrillation originate from the left atrial appendage [3]. The direct factor Xa inhibitor apixaban is superior to warfarin in terms of stroke prevention with a lower risk of bleeding and mortality [4].

Is left atrial appendage closure useful for stroke prevention in atrial fibrillation patients with renal failure?
With great interest we read the article by Kefer et al. about the impact of chronic kidney disease on left atrial appendage (LAA) occlusion with the ACP device for stroke prevention in patients with atrial fibrillation (AF) [1]. We agree with the authors that stroke prevention in AF patients with chronic kidney disease is a problem due to increased bleeding complications during oral anticoagulant therapy with vitamin K antagonists. Furthermore, the use of non-vitamin K-antagonist oral anticoagulants (NOACs) is dangerous or contraindicated in these patients.
