Initial results of a new very rapid rest/regadenoson stress myocardial perfusion protocol in patients with atrial fibrillation
Background Cardiovascular magnetic resonance (CMR) myocardial perfusion is a well established method for detection of significant obstructive coronary artery disease (CAD). In patients with arrhythmias, standard methods using ECGgating can result in poor image quality. Additionally, with typical stress/rest protocols, a true rest state may not be achieved after administration of regadenoson. Ho...
متن کاملEvaluation of ischaemia in patients with atrial fibrillation: impact of stress protocol on myocardial perfusion imaging accuracy.
BACKGROUND To evaluate the accuracy of myocardial perfusion imaging (MPI) on a novel cadmium-zinc-thelluride camera in detecting significant coronary artery disease (CAD) in patients with atrial fibrillation (AF). METHODS AND RESULTS Seventy-four subjects with AF submitted to stress-rest MPI and coronary angiography were consecutively enrolled. One hundred and forty-eight patients in sinus rh...
متن کاملClinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction
Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) 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 (251 m...

15 صفحه اولTwo-day stress-rest lower limbs perfusion scan in patients referred for myocardial perfusion imaging
Introduction: Peripheral Vascular Disease (PVD) is a major cause of morbidity and is associated with Coronary Artery Disease (CAD). We aimed to perform Lower Limb Perfusion Scan (LLPS) in patients referred for Myocardial Perfusion Imaging (MPI) and estimate prevalence of PVD in subgroups with normal and abnormal MPI results. We also compared quantitative indices of LLPS in pati...
