In such patients, a cardiac embolus, most commonly a thrombus originating from the left atrial appendage (LAA), is the cause of the ischemic stroke. (See "Clinical diagnosis of stroke …

Jan 19, 2016 · AF and stroke have been associated in rigorous studies, 4 indicating a true association rather than a spurious finding. Epidemiological logic suggests 3 explanations: (1) AF causes stroke, (2) stroke causes AF, and (3) AF is associated with other factors that cause stroke.

Dec 14, 2020 · Ischemic strokes related to atrial fibrillation are highly prevalent, presenting with severe neurologic syndromes and associated with high risk of recurrence.

Atrial fibrillation (AF) is an important risk factor for ischemic stroke resulting in a fivefold increased stroke risk and a twofold increased mortality.

Atrial fibrillation (AF) is a leading preventable cause of ischemic stroke for which early detection and treatment are critical. The risk of stroke in people with AF can be stratified by the use of such validated prediction instruments such as CHADS 2 or CHA 2 DS 2 –VASc.

Atrial fibrillation (AF) is an important risk factor for ischemic stroke (IS). Oral anticoagulation (OAC) significantly reduces the risk of IS in AF but also increases the risk of systemic bleeding, including intracerebral hemorrhage (ICH).

Nov 20, 2012 · Atrial fibrillation (AF) increases the risk of stroke and is associated with poor stroke outcomes. Limited tools are available to evaluate clinical outcomes and response to thrombolysis in stroke patients with AF.

The most frequent underlying cause of cardioembolic stroke is atrial fibrillation (AF), a disease that affects almost 3 million people in the USA and 4.5 million in Europe. AF increases the risk of ischemic stroke by a factor of 3 to 5 times.

Although the cause of ischemic stroke can be multifactorial, the presence of atrial fibrillation (AF) brings forth a fivefold increase in ischemic stroke risk [2]. Altered interatrial flow dynamics in AF, among other processes, predispose patients to thrombus formation.

Jan 1, 2024 · About 25% of ischaemic stroke are cardio-embolic in origin; AF is the most common cause of those. 1 Nonvalvular AF carries a 5-fold increased risk of stroke, 2 while AF related to mitral stenosis increases the risk of stroke by 20-fold. 3 The attributable risk of stroke for AF increases with age unlike other factors such as hypertension for inst...
