- W2331680648 abstract "An M-mode echocardiographic study was performed on 10 normal patients and 5 compensated pressure overload (CPO) patients. The end-systolic longitudinal area ratio, ARφ (ES), was defined as the wall cross-sectional area at end-systole divided by the wall cross-sectional area at enddiastole and taken as a measure of myocardial wall deformation. The average value of ARφ (ES) for the 10 normal patients (1.26 ± .24) was very similar to the average value of ARφ determined by cineangiography in a previous study (1.27 ± .14). For the first time, a CPO patient population has been analyzed for ARφ (ES) and was found to be 2.031 ± .439 which is definitely elevated over the normal population (p<.025). The study is significant since it shows that: (1) measurements required to calculate ARφ can be obtained non-invasively by echocardiography which makes ARφ (ES) available as a routine, screening measurement of patient populations as contrasted with cineangiography; and, (2) a large amount of myocardial wall deformation apparently occurs as part of the compensatory left ventricular process." @default.
