Left atrial size is independently associated with cognitive function

persistent isolated right atrial standstill associated with left atrial tachycardia

introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...

Pericardial fat is independently associated with human atrial fibrillation.

OBJECTIVES The purpose of this study was to investigate the association between atrial fibrillation (AF) and pericardial fat. BACKGROUND Pericardial fat is visceral adipose tissue that possesses inflammatory properties. Inflammation and obesity are associated with AF, but the relationship between AF and pericardial fat is unknown. METHODS Pericardial fat volume was measured using computed t...

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...

comparison of left atrial function between hypertensive patients with normal atrial size and normotensive subjects using strain rate imaging technique

Arterial stiffness is associated with left atrial size in hypertensive patients.

BACKGROUND Arterial stiffness is a strong predictor of cardiovascular events and particularly of stroke. A likely explanation is the development of atherosclerotic lesions at the carotid level, favored by increased local stiffness. Another possibility involves cardiac consequences of aortic stiffness and particularly left atrial dilatation with its subsequent risk of atrial fibrillation (AF) an...
