CINE-MRI to study the progress of disease in a chronic atrial fibrillation goat model
نویسندگان
چکیده
Background Atrial fibrillation (AF) is a common sustained cardiac arrhythmia associated with increased risks of heart failure, left ventricle (LV) dysfunction, and known to cause an increase in left atrium (LA) volume with decrease in atrial contractility. Cine magnetic resonance images (MRI) were used to measure changes in LA and LV function in a chronic AF goat model. Ejection fraction (EF), end diastolic volume (EDV), end systolic volume (ESV), and stroke volume (SV) measurements of both the LV and LA were made from cine-MR images to track the progression of disease in goats that were induced with AF using neurostimulators.

متن کاملAssessment of P-wave indices as atrial fibrillation predictors in psoriasis patients
Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...
متن کاملLower left atrial strain in the presence of regional atrial fibrosis: an MRI study of patients with atrial fibrillation
Background LA strain, measured by feature-tracking using cine MRI, is an emerging tool for regional evaluation of the left atrium [1-4]. Late gadolinium enhancement (LGE MRI) is a method which indicates regions of possible atrial fibrosis. Their regional relationship is not known. Our goal was to compare global and regional left atrial (LA) strain in atrial fibrillation (AF) subjects and contro...

Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...
