BACKGROUND Whether different ablation strategies affect paroxysmal atrial fibrillation (AF) long-term freedom from AF/atrial tachyarrhythmia is unclear. We sought to compare the effect of 3 different ablation approaches on the long-term success in patients with paroxysmal AF. METHODS AND RESULTS One hundred three consecutive patients with paroxysmal AF scheduled for ablation and presenting in...
AIMS In this study, we investigated for a potential mechanism by which atrial fibrillation (AF) might convey a worse prognosis in congestive heart failure (CHF). Specifically, we aimed to determine whether AF impaired cardiac sympathetic response to baroreceptor unloading in comparison to sinus rhythm (SR) in CHF. METHODS AND RESULTS Eighteen CHF patients (ejection fraction 30+/-2%, age 59+/-...
BACKGROUND It is critical to recognize high risk patients who are prone to develop stroke in the management of atrial fibrillation (AF). The purpose of this study was to identify the determinants of AF related stroke by assessing the anatomical and functional remodeling of cardiac chambers. METHODS We compared the cardiac structure and function of 28 consecutive patients with paroxysmal and p...
We performed a matched case-control study using a propensity score matching, to assess the association of Th17-related cytokines, including interleukin (IL) 17A (IL-17A), IL-17F, IL-21, IL-22 and IL-6, along with interferon-γ (IFN-γ), IL-10, IL-9, and IL-4, with the risk of AF. A total of 336 patients with AF were matched 1:1 with patients without AF. Plasma levels of cytokines were measured us...
Background: The preventive effects of renin-angiotensin system inhibitors for suppression of newonset atrial fibrillation (AF) are unclear. In the present study, we evaluated the effect of angiotensin receptor blocker (ARB)/ angiotensin converting enzyme inhibitor (ACEI) on the incidence of newonset AF in patients with heart failure (HF). Methods: The study subject consisted of 525 patients wit...
Bioceramics, such as silica-based glasses, are widely used in bone and teeth restoration. Nowadays, the association between nanotechnology and pharmacology is one of the most promising research fields in cancer therapy. The advanced processing methods and new chemical strategies allow the incorporation of drugs within them or on their functionalized surfaces. Bioceramics can act as local drug d...
BACKGROUND Only a few population-based cohort studies have investigated the impact of atrial fibrillation (AF) on stroke in Japan. METHODS A total of 10 929 participants (4147 men and 6782 women) were included in this population-based prospective cohort study. Baseline data, including electrocardiograms (ECGs) to ascertain AF status, were obtained from April 1992 through July 1995 in 12 areas...
BACKGROUND Compared with left atrial (LA) dimension, LA emptying fraction (LAEF) has received less emphasis as a predictor of atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). In addition, patients experiencing post-RFCA AF recurrence may respond to previously ineffective antiarrhythmic drugs (AADs). Classifying these patients into a third RFCA outcome category ...
dpph radical-scavenging activity of the bene hull oil (bho), sesame oil (seo), rice bran oil (rbo), the oils' methanolic (ch3oh/h2o, 80:20 v/v) or hexane extracts, and their unsaponifiable matters fraction were measured and compared with each other. as a radical-scavenger, seo was significantly stronger than rbo and bho, respectively. unlike bho and rbo, the unsaponifiable (usm) fraction of the...
BACKGROUND Atrial fibrillation (AF) in WPW syndrome occurs earlier and is more common than in the general population. AIM To evaluate the predisposing factors for the first episode of AF in patients with WPW. METHODS We analysed data on 930 patients (510 males, 420 females) with WPW treated in our centre during 1988-2007. AF was diagnosed in 236 patients (25% - 161 males, 75 females, aged 3...
