Introduction: Previous studies have underscored the importance of the interpulmonary isthmus in the initiation and maintenance of atrial fibrillation (AF). The efficacy of additional radiofrequency energy delivery in the interpulmonary isthmus following pulmonary vein antral isolation (PVAI) was investigated.
Methods And Results: A total of 76 patients (49 males, mean age 56.
Background: Obesity is a well established risk factor for atrial fibrillation (AF) development. Our purpose was to determine the impact of body mass index (BMI) on the safety and efficacy of radiofrequency catheter ablation of AF.
Methods: Two hundred and twenty-six consecutive patients with symptomatic, drug-refractory paroxysmal (59.
Uric acid elevation in atrial fibrillation.
Hellenic J Cardiol
November 2010
Introduction: Uric acid is a cardiovascular risk marker associated with oxidative stress and inflammation. Recently, atrial fibrillation (AF) has been associated with inflammation and oxidative stress. We therefore investigated the association between AF and uric acid levels.

Methods: One hundred and ten ECGs with paroxysmal narrow QRS complex, short RP tachycardia were evaluated. Subjects with overt ventricular pre-excitation during sinus rhythm were excluded from the study.
Objective: The present study aimed to compare the effectiveness and safety of the potential- and the anatomic-guided approach for slow pathway ablation in patients with recurrent episodes of symptomatic common type atrioventricular (AV) nodal reentrant tachycardia.
Methods: Two hundred and twenty-eight patients were randomly assigned to undergo either a potential- (n=114, 47% men, mean age 52.85 +/- 14.
Background: Limited data are available on the predictors of atrial fibrillation (AF) recurrence in patients with chronic AF.
Objectives: To evaluate potential clinical, echocardiographic and electrophysiological predictors of AF recurrence, after internal cardioversion for long-lasting AF.
Methods: A total of 99 consecutive patients (63 men and 36 women, mean age 63.
Background: Previous studies have demonstrated a high incidence of atrial tachyarrhythmias (ATs) in patients with Brugada syndrome (BS). The present study aimed to investigate whether various 12-lead electrocardiogram (ECG) and electrophysiological parameters may help to differentiate subjects with a high probability to develop ATs.
Methods And Results: The clinical records of 38 individuals (31 males, age 44.
Aims: An increasing body of evidence has demonstrated the essential role of inflammation in the genesis and maintenance of atrial fibrillation (AF). The aim of the present study was to investigate whether success or failure of electrical pulmonary vein isolation (PVI) in patients with AF is related with the presence of a pre-ablative inflammatory state as determined by known clinical parameters and conventional markers of inflammation including high-sensitivity C-reactive protein, white blood cell (WBC) count, and fibrinogen.
Methods And Results: Seventy-two patients with paroxysmal (64%) or persistent AF (36%) underwent successful electrical PVI.
Objectives: The present study aimed to investigate the clinical and echocardiographic determinants of plasma NT-pro-BNP levels in patients with atrial fibrillation (AF) and preserved left ventricular ejection fraction (LVEF).
Methods: NT-pro-BNP levels were measured in 45 patients with paroxysmal AF, 41 patients with permanent AF and 48 controls.
Results: NT-pro-BNP levels were found significantly elevated in patients with paroxysmal (215+/-815 pg/ml) and permanent AF (1,086+/-835 pg/ml) in relation to control population (86.
Introduction: The management of patients with heart failure and atrial fibrillation (AF) is a medical challenge, especially in the case of patients in whom sinus rhythm or rate control cannot be achieved with optimal pharmaceutical treatment.
Methods: Thirteen consecutive patients (11 men and 2 women, 35-70 years old, median age 55 +/- 23 years) with heart failure (NYHA I-IV, median ejection fraction 35 +/- 5%, range 25-40%) and symptomatic persistent (10 patients, 76.9%) or permanent (3 patients, 23.
Objective: We examined the intake of dietary micronutrients of immigrant Arabian pregnant women in Greece, in order to investigate the possible factors influencing food intake and affecting the overall nutritional profile.
Methods: A dietary assessment of 497 immigrant Arabian pregnant women, admitted to the Obstetrics and Gynecology Department, Outpatient Clinic, Tzaneion General Hospital, Piraeus city, Vyronas Health Center, and Alexandras General Hospital, Athens, Greece was performed between August 2002 and August 2005, along with a comparison of micronutrient intake with the latest dietary recommendations. We carried out blood analysis, and measurements of serum micronutrients in all participants.
