Left 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...
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 Aortic Stiffness in Middle-aged Patients with the First Episode of Atrial Fibrillation
BACKGROUND In the early stages of atrial remodeling, aortic stiffness might be an indication of an atrial myopathy, in particular, atrial fibrosis. This study aimed to investigate the association between left atrial (LA) mechanical function, assessed by two-dimensional speckle tracking echocardiography, and aortic stiffness in middle-aged patients with the first episode of nonvalvular atrial fi...
متن کاملEffect of atorvastatin on left atrial function of patients with paroxysmal atrial fibrillation.
The aim of this study was to evaluate the effects of atorvastatin on left atrial (LA) function in paroxysmal atrial fibrillation patients. Fifty-eight paroxysmal atrial fibrillation patients were divided into two groups (treatment and control groups). The echocardiography parameters, including LA active emptying volume (LAAEV), LA active emptying fraction, LA maximum volume, LA total emptying v...
متن کاملAssociation Between Left Atrial Stiffness Index and Atrial Fibrillation Recurrence in Patients Undergoing Left Atrial Ablation.
BACKGROUND Atrial fibrillation (AF) is associated with significant abnormalities of left atrial (LA) systolic and diastolic function. This study describes a novel measure, LA stiffness index, that estimates LA diastolic function and its association with clinical outcomes of catheter ablation. METHODS AND RESULTS A total of 219 AF patients referred for ablation (59% paroxysmal, mean CHA2DS2VAS...
