Disturbed Left Atrial Function is Associated with Paroxysmal Atrial Fibrillation in Hypertension
BACKGROUND Hypertension is the most prevalent and modifiable risk factor for atrial fibrillation. The pressure overload in the left atrium induces pathophysiological changes leading to alterations in contractile function and electrical properties. OBJECTIVE In this study our aim was to assess left atrial function in hypertensive patients to determine the association between left atrial functi...
متن کاملLeft atrial appendage aneurysm with paroxysmal atrial fibrillation.
Aneurysm of the left atrial appendage is extremely rare, and afflicted patients most commonly present with atrial tachyarrhythmia or thromboembolism. For these patients, resection of the aneurysm is the recommended and preferred therapy. We present the case of a 57-year-old woman who was found incidentally to have a large aneurysm of the left atrial appendage presenting as atrial fibrillation. ...
متن کاملPersistent Atrial Fibrillation Is Associated with Worse Prognosis Than Paroxysmal Atrial Fibrillation in Acute Cerebral Infarction
Background and Purpose. We hypothesized that patients with persistent atrial fibrillation (AF) suffer from more severe cerebral infarction than patients with paroxysmal AF due to differences in clot structure and volume. Methods. This study includes consecutive patients with acute cerebral infarction and persistent or paroxysmal AF documented by ECG any time prior to stroke onset. The National ...
متن کاملSignificant impairment of left atrial function in patients with cardioembolic stroke caused by paroxysmal atrial fibrillation.
OBJECTIVE Patients with cardioembolic stroke (CE) caused by paroxysmal atrial fibrillation (Paf) sometimes show normal sinus rhythm on admission, which makes it difficult to diagnose them as having CE. The present study examined the differences in echocardiographic findings between patients with CE caused by Paf (the Paf-CE group) and those with non-cardiogenic embolic ischemic stroke (the Non-...
متن کاملLeft Atrial Mechanical Function and Stiffness in Patients with Paroxysmal Atrial Fibrillation
BACKGROUND Abnormalities in the left atrial (LA) structure and function may develop in patients with paroxysmal atrial fibrillation (AF). We sought to determine the contribution of LA mechanical function, including LA stiffness, to AF by comparing patients with paroxysmal AF with normal control subjects, and to evaluate whether LA mechanical function and stiffness are related with the structura...
