BACKGROUND Atrial fibrillation(AF) is the most common arrhythmia in the adult population. The activated renin-angiotensin-aldosterone system (RAS) has been reported to play an important role in the pathogenesis of atrial fibrillation. The aim of this study was to investigate the association between nonfamilial AF and polymorphisms in RAS gene. METHODS A total of 931 patients with nonfamilial ...
the present study carried out to identify neo tectonic activity of the gorgan river basin in golestan province, in north of eastern alborz range is investigated by four geomorphic indices including the streamâ gradient index (sl), drainage basin asymmetry (af), reveres symmetry of topography (t) and mountain front sinuosity (smf). result from the analysis is accumulated and expressed as an in...
Atrial Fibrillation: General Considerations Atrial fibrillation (AF), a common adult cardiac arrhythmia, involves abnormal atrial contractions. As every medical student is taught, it is easily diagnosed as an irregularly irregular pulse and loss of organized atrial activity on an ECG. Clinical interest in AF is considerable because AF is the most common adult arrhythmia that increases in preval...
Abstract: Information flow is a key parameter in an economic activity and acts as a key factor in the emergence, stability and efficiency of capital markets. The purpose of this paper is to investigate the effect of disclosure quality on the value of information and changes in the quality of accounting information. For this purpose, the data of the companies listed in the Tehran Stock Exchange ...
BACKGROUND Atrial fibrillation (AF), whether silent or symptomatic, is a frequent and severe complication of acute myocardial infarction (AMI). Asymmetric dimethylarginine (ADMA), an endogenous eNOS inhibitor, is a risk factor for endothelial dysfunction. We addressed the relationship between ADMA plasma levels and AF occurrence in AMI. METHODS 273 patients hospitalized for AMI were included....
Hypertension is the most prevalent risk factor for incident atrial fibrillation (AF). Recently, even high normal blood pressures (BPs) have been established as predictive of AF in women. We aimed to study the long-term impact of upper normal BP on incident AF in a population-based study of middle-aged men. From 1972 to 1975, 2014 healthy Norwegian men were included in a prospective cardiovascul...
Relations of Liver Fat With Prevalent and Incident Atrial Fibrillation in the Framingham Heart Study
BACKGROUND Obesity is an important risk factor for nonalcoholic fatty liver disease and atrial fibrillation (AF). Less is known about the relations between nonalcoholic fatty liver disease and AF. We sought to evaluate the association between fatty liver and prevalent and incident AF in the community. METHODS AND RESULTS We examined Framingham Heart Study participants who underwent a study-di...
Atrial fibrillation (AF) is the most common sustained arrhythmia, causing a 2-fold increase in mortality and a 5-fold increase in stroke. The Asian population is rapidly aging, and in 2050, the estimated population with AF will reach 72 million, of whom 2.9 million may suffer from AF-associated stroke. Therefore, stroke prevention in AF is an urgent issue in Asia. Many innovative advances in th...
Background: Approximately 25% of strokes are cryptogenic in origin and identifying atrial fibrillation (AF) as an etiologic factor in this situation has major therapeutic implication. Standard Holter ECG has a low sensitivity for AF detection in this patient group. Aim: To assess the diagnostic yield of prolonged ambulatory noninvasive ECG telemonitoring for AF detection in cryptogenic stroke o...
BACKGROUND Atrial fibrillation (AF) is a growing public health problem without adequate therapies. Angiotensin II and reactive oxygen species are validated risk factors for AF in patients, but the molecular pathways connecting reactive oxygen species and AF are unknown. The Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) has recently emerged as a reactive oxygen species-activated proarrh...
