background: selenium (se) is an essential trace element mainly obtained from seafood, meat, and cereals. se deficiency has been identified as a major contributing factor in the pathogenesis of certain congestive heart failure (chf) syndromes. since there is controversy over the prevalence of se deficiency among patient with chf, the aim of this study was to assess the serum se concentrations in...

introduction pulmonary vein (pv) isolation is considered as a key to atrial fibrillation (af) treatment. cryoballoon ablation is an effective therapy for pv isolation for af with minimal side effects and was approved by the us food and drug administration (fda) several years ago. successful isolation of pvs during cryoablation depends on the balloon temperature and helps in early identification...

the prevalence of atrial fibrillation (af) is 1-2 % in the general population, and the risk of embolic stroke in af patients is 4-5 times higher than that in the general population. af-related strokes are often severe, and the rate of permanent disability is much higher among individuals who have af-related strokes than in those who have strokes unrelated to af. in patients with af, more than 9...

atrial fibrillation (af) is a commonly encountered arrhythmia in our daily practice. every year a huge bulk of data is published about different management strategies, new antiarrhythmic drugs, anticoagulation protocols and ablation procedures in these patients. in this review article, we discuss different management strategies and new antiarrhythmic drugs as well as those commonly used. we wil...

introduction: atrial fibrillation (af) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. the goal of this article is to clarify an overview of the evidence linking inflammation to af existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of af by modulating inflammatory pathways. mat...

results: the average of dyssynchrony in eight cycles showed a positive correlation with dyssynchrony in target beat rr1/rr2 = 1. average of dyssynchrony in target beat was 46.77 msec, and average of 8 cycle was = 47.701, (p value = 0.776, pearson linear correlation 0.769). objectives: we proposed to evaluate intraventricular mechanical dyssynchrony by measuring time-to-peak systolic velocity be...

background: atrial fibrillation (af) after coronary artery bypass graft (cabg) is a common complication with potentially higher risk of adverse outcome and prolonged hospital stay. objective: to determine the impact of postoperative af (poaf) on long-term outcome in a large cohort of patients who underwent cabg. patients and methods: we conducted an observational cohort study of 989 patients wh...

we are presenting a case illustrating atrial fibrillation (af) following the use of methylprednisolone in a patient with pelvic and femur fracture. a 48- year- old man with no significant past medical history, was admitted to the emergency department after injury in a car accident. he suffered a multiple bone fracture with chief complaints of pain and shortness of breath. he was transferred to ...

background: atrial fibrillation (af) is prevalent among cardiac patients; and as the risk of thromboembolism is high in this arrhythmia, discrimination of the effective risk factors in producing left atrial (la) thrombosis is clinically important. the molecular structure of lipoprotein(a) [lp(a)] is very similar to plasminogen , so it can be hypothesized that the high level of lp(a) is a compro...
