Treatment strategies for chronic hepatitis B (CHB) using either interferon or Lamivudine can achieve sustained response in 30-40 % in HBeAg positive CHB. Retreatment of treatment failure in CHB and treatment of HBeAg negative patients pose major therapeutic challenge. Because of success story of Peginterferon in hepatitis C and some ...

AF leads to electrophysiological changes, but it is not known if similar alterations also appear before the onset of the first episode of AF because invasive electrophysiological studies are not justified in otherwise symptom-free patients. To address this question requires a safe method of obtaining atrial electrophysiological parameters at no ...

The aim of this prospective study was to compare the long-term follow-up after transisthmic ablation of patients with preablation lone atrial flutter, coexistent AF, and drug induced atrial flutter to determine if postablation AF followed a different clinical course and displayed different predictors in these groups. The study evaluated 357 ...

Atrial fibrillation (AF) has been treated with DC shocks delivered transthoracically, but in 5-30% of patients, the procedures fail to restore sinus rhythm (SR). We hypothesized that applying high energy shock waves to the chest may overcome the inadequate penetration of electrical shock to the atrium. The aim of this ...

INTRODUCTION: Modification of AV nodal conduction by radiofrequency ablation (RFA) results in a variable reduction in heart rate during atrial fibrillation (AF). Using AF induced in patients with dual AV nodal pathways as a model, we tested the effect of additional treatment with digitalis (ouabain) and beta-blocker (esmolol). METHODS AND ...

Predictors of the development of atrial fibrillation (AF) in patients who have hypertrophic cardiomyopathy (HC) have not been extensively studied, although, in these patients, AF contributes to the exacerbation of symptoms and the development of heart failure. The present study determined the role of left atrial (LA) function in the ...

To investigate whether new onset acute atrial fibrillation (AF) of < 48 hours' duration creates a prothrombotic state in the absence of anticoagulation and to assess the evolution in research indices after spontaneous or pharmacological cardioversion. 24 patients were recruited with first onset acute non-rheumatic AF, in whom sinus rhythm ...
Callans David J - - 2004
INTRODUCTION: Pulmonary vein (PV) isolation is effective in the treatment of most patients with atrial fibrillation (AF). Some advocate the addition of linear ablation techniques to improve efficacy; however, previous studies suggest recurrent PV conduction is responsible for AF recurrence. The aim of this study was to determine the effectiveness ...

This chapter about antithrombotic therapy in atrial fibrillation (AF) is part of the Seventh ACCP Conference on Antithrombotic and Thrombolytic Therapy: Evidence Based Guidelines. Grade 1 recommendations are strong and indicate that the benefits do, or do not, outweigh risks, burden, and costs. Grade 2 suggests that individual patients' values ...

Atrial fibrillation (AF) is a major cause of morbidity and mortality from stroke due to thromboembolism from the fibrillating left atrium, including its appendage. We hypothesized that indexes of inflammation (as indicated by C-reactive protein and interleukin-6) and indexes of the prothrombotic state in AF that represent platelet activation (soluble ...

BACKGROUND AND PURPOSE: Although atrial fibrillation is the most frequent cause of cardioembolic stroke, this arrhythmia remains underdiagnosed, as it is often asymptomatic or intermittent and, thus, may not be detected on standard 12-lead ECG or even 24-hour ECG recording (Holter). In this study, we hypothesized that 7-day ambulatory ECG ...

BACKGROUND: In myocardium of patients with chronic atrial fibrillation (AF) the expression of the mitochondrial heat shock proteins HSP60 and HSP10 is increased. They are responsible for folding and translocation of proteins inside the mitochondria. Import of these proteins is accomplished by mortalin. The aim of our study was to ...

The aponeurotic layer is a very important element to consider during abdominoplasty. For most patients, a simple midline plication is enough to obtain good results. However, for in patients with severe aponeurotic laxity, some other maneuvers must be performed. The purpose of this study was to evaluate the use of ...

Atrial fibrillation (AF) is now regarded as the arrhythmia for which patients are hospitalized the most frequently, an arrhythmia that is responsible for significant morbidity and mortality. Of particular importance is that the arrhythmia is associated with a significant incidence of thromboembolism which may induce disabling and incapacitating strokes, sometimes ...

CONTEXT: Large, multi-institutional studies often involve merging data records that have been de-identified to protect patient privacy. Unless patient identities can be reconciled across institutions, individuals with records held in different institutions will be falsely "counted" as multiple persons when databases are merged. OBJECTIVE: The purpose of this article is ...

BACKGROUND AND AIM OF THE STUDY: Systemic thromboembolism is a major complication in patients with mitral stenosis (MS), especially in those who have atrial fibrillation (AF). It has been suggested that systemic coagulation activity may be increased in these patients. The study aim was to investigate the relationship between control ...
Wijffels Maurits C E F - - 2004
AF remains the most common and most challenging arrhythmia. Although several new treatment modalities are available to restore and maintain sinus rhythm, the long-term success of such a strategy remains disappointing, often making rate control a good alternative. Factors associated with failures to restore and maintain sinus rhythm thereafter are ...

Atrial fibrillation (AF) and paroxysmal AF (PAF) are common causes of stroke which may not be detected by a single electrocardiogram (EKG). We conducted a prospective study to determine if 48 hours of telemetry monitoring increased the rate of detection of AF in patients with acute stroke and thus identified ...
