Reduction in postsystolic wall thickening during late preconditioning.
Brief coronary artery occlusion (CAO) and reperfusion induce myocardial stunning and late preconditioning. Postsystolic wall thickening (PSWT) also develops with CAO and reperfusion. However, the time course of PSWT during stunning and the regional function pattern of the preconditioned myocardium remain unknown. The goal of this study was to investigate the evolution of PSWT during myocardial ...
متن کاملEchocardiographic Assessment of Left Ventricle Torsion by Tissue Doppler and Velocity Vector Imaging
Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...
متن کاملDynamic myocardial CT perfusion imaging for evaluation of myocardial ischemia as determined by MR imaging.
OBJECTIVES The aim of this study was to determine the feasibility of computed tomography (CT)-based dynamic myocardial perfusion imaging for the assessment of myocardial ischemia and infarction compared with cardiac magnetic resonance (CMR). BACKGROUND Sequential myocardial CT perfusion imaging has emerged as a novel imaging technique for the assessment of myocardial hypoperfusion. METHODS ...
متن کاملMYOCARDIAL ISCHEMIA Impaired thickening of nonischemic myocardium during acute regional ischemia in the dog
To study the regional function of nonischemic myocardium after the onset of regional ischemia, graded circumflex coronary arterial stenosis was induced in 18 open-chest anesthetized dogs. Two-dimensional echocardiographic views were obtained at each degree of occlusion in a crosssectional plane marked by two to three metal beads sewn to the left ventricular epicardium. Percent systolic thickeni...
