A genotype-dependent intermediate ECG phenotype in patients with persistent lone atrial fibrillation genotype ECG-phenotype correlation in atrial fibrillation.
BACKGROUND Atrial fibrillation (AF) is heterogeneous at the clinical and molecular levels. Association studies have reported that common single-nucleotide polymorphisms in KCNE1 and SCN5A may predispose to AF. In this study, we tested the hypothesis that specific AF-associated genotypes confer variation on the appearance of AF assessed by analysis of fibrillatory rate of the atria. METHODS AN...
متن کاملA Functional Polymorphism C-509T in TGFβ-1 Promoter Contributes to Susceptibility and Prognosis of Lone Atrial Fibrillation in Chinese Population
Transforming growth factor-β1 (TGF-β1) is an important mediator of atrial fibrosis and atrial fibrillation (AF). But the involved genetic mechanism is unknown. Herein, the TGF-β1 C-509 T polymorphism (rs1800469) was genotyped in a case-control study of 840 patients and 845 controls in Chinese population to explore the association between the polymorphism and susceptibility and prognosis of lone...
متن کاملAtrial fibrillatory rate and risk of left atrial thrombus in atrial fibrillation.
AIMS In atrial fibrillation (AF), a relation between electrocardiogram (ECG) fibrillatory wave amplitude and thrombus formation has been sought for long with conflicting results. In contrast, the possible relation between atrial fibrillatory rate obtained from the surface ECG and left atrial thrombus formation in patients with AF is unknown and was consequently evaluated in this study. METHOD...
متن کاملMechanical discordance of the left atrium and appendage: a novel mechanism of stroke in paroxysmal atrial fibrillation.
BACKGROUND AND PURPOSE Thromboembolism in paroxysmal atrial fibrillation (AF) has often been attributed to occult AF. We hypothesized that the surface ECG may not always reflect left atrial appendage (LAA) mechanical function. METHODS Transesophageal echocardiographic images from 201 consecutive patients undergoing transesophageal echocardiography by a single operator were reviewed. LAA pulse...
متن کاملCorrelation between Mean Serum Ferritin Levels and Atrial Electrocardiographic Markers in Beta-Thalassemia Major
Background: Atrial fibrillation (AF) is the most common arrhythmia in patients with β-thalassemia major (β-TM) due to cardiac iron overload. AF may be predicted by changes in P wave parameters. The aim of this study was to evaluate the correlation between P-wave parameters and atrial markers with mean serum ferritin levels measured yearly. Methods: Fifty patients with β-TM and 50 healthy subje...
