BACKGROUND Former studies showed possible interrelationship between altered ventricular filling patterns and atrial fibrillation (AF). HYPOTHESIS Long term persistent AF has a negative impact on left ventricular filling in patients with preserved ejection fraction of left ventricle. METHODS Our study was designed as a prospective case control study. We included 40 patients with persistent A...

BACKGROUND In drug-refractory heart failure, cardiac resynchronization therapy (CRT) is an established method in patients with sinus rhythm, severe reduced ejection fraction and broad QRS. Heart failure is known as a predisposition for atrial fibrillation (AF). However, the putative impact of atrioventricular node (AVN) ablation in chronic AF and CRT remains unclear. The aim of this study was t...

The black soldier fly larvae (BSFL) is a sustainable ingredient for feed applications, biofuels, composite materials and other biobased products. Processing BSFL to obtain lipid protein fractions with enhanced functional properties as suitable replacement conventional ingredients has gained considerable momentum. In this regard, novel wet mode fractionation (WMF) scheme was explored. Fresh were...

BACKGROUND Atrial fibrillation (AF) is associated with left atrial (LA) structural and functional changes. Cardiac magnetic resonance late gadolinium enhancement (LGE) and feature-tracking are capable of noninvasive quantification of LA fibrosis and myocardial motion, respectively. We sought to examine the association of phasic LA function with LA enhancement in patients with AF. METHODS AND ...

background: p wave dispersion (pwd) is defined as the difference between the maximum p wave duration (p max ) and the minimum p wave duration (p min ) in 12-leads of the surface electrocardiography. the aim of this study was to evaluate the values of pwd during atrial fibrillation (af) after acute myocardial infarction (ami).   methods: we prospectively evaluated atrial rhythms of 350 patients ...

Patients: 18 201 patients (median age 70 y, 65% men) who had AF or atrial flutter and ≥ 1 of the following: age ≥ 75 years; previous stroke, systemic embolism, or transient ischemic attack; symptomatic heart failure within 3 months or left ventricular ejection fraction ≤ 40%; diabetes mellitus; or hypertension. Exclusion criteria included AF due to a reversible cause; moderate or severe mitral ...

BACKGROUND Patients with heart failure (HF) and atrial fibrillation (AF) have higher circulating levels of NT-proBNP (N-terminal pro-B-type natriuretic peptide) than HF patients without AF. There is uncertainty about the prognostic importance of a given concentration of NT-proBNP in HF patients with and without AF. We investigated this question in a large cohort of patients with HF and reduced ...

OBJECTIVES This study sought to determine the influence of stature on atrial fibrillation (AF) in high-risk patients with reduced left ventricular (LV) systolic function. BACKGROUND Left atrial (LA) enlargement is a potent risk factor for AF. Because LA size is strongly associated with stature, we hypothesized that height and body surface area (BSA) are risk factors for AF, independent of oth...

OBJECTIVES The aim of this study was to investigate the factors associated with the development of atrial fibrillation (AF) and to examine the impact of these factors for long-term outcome after cardiac resynchronization therapy (CRT). BACKGROUND The effect of CRT on the development of new AF is under debate. METHODS Clinical assessment, 12-lead electrocardiogram, echocardiography with spec...
