End-systolic measures of regional ventricular performance.
Dimension change measures of regional ventricular function, such as absolute or percent wall thickening (delta T or % delta T) or segmental shortening (delta L or % delta L), are highly load dependent. In 16 anesthetized mongrel dogs we assessed use of the end-systolic pressure-thickness and end-systolic pressure-length relationships (ESPTR, ESPLR) as more load-independent measures of regional ...

Dimension change measures of regional ventricular function, such as absolute or percent wall thickening (AT or %AT) or segmental shortening (AL or %AL), are highly load dependent. In 16 anesthetized mongrel dogs we assessed use of the end-systolic pressure-thickness and endsystolic pressure-length relationships (ESPTR,ESPLR) as more load-independent measures of regional function. We found that ...
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...

متن کاملReal time MRI of border zone end-systolic regional work
Background Heart failure results in 280,000 deaths each year in the US and post-myocardial infarction (MI) remodeling is among the leading causes. An unresolved question is the integrity of the molecular contractile apparatus in the peri-infarct or borderzone (BZ) myocardium and the resulting effect on infarct stretching and thinning and BZ expansion. A difficulty is the lack of available metho...
