Heart Test Labs Announced Today the Acceptance by the American Society of Echocardiography of a Clinical Trial Abstract Utilizing Their MyoVista Technology
Colleyville, TX, March 02, 2011 --(PR.com)-- Heart Test Laboratories MyoVista technology has been accepted as an abstract by the American Society of Echocardiography. It is noted that these results provide continuing evidence that the MyoVista™ technology will be a superior diagnostic tool over conventional ECG.
The MyoVista provided data which confirmed the existence of Myocardial Abnormalities of Hypertensive patients.
65 patients, including 49 with systemic hypertension and 16 control subjects were studied in the trial. Myocardial repolarization was assessed by the MyoVista™ system in relation to 2-dimensional LV normal strains. Regional time volume curves by 3-dimensional speckle tracking echocardiography were also obtained. Segmental dyssynchrony in onset of LV relaxation was measured as the standard deviation of the cross-over point of minimum systolic volume for the number of segments analyzed.
The results showed that hypertensive patients with reduced LV longitudinal strain showed increase in systolic stretch in the longitudinal strains; while stretch in circumferential direction remained unchanged. Patients with reduced longitudinal strain showed higher repolarization abnormalities, and dispersed shortening-lengthening cross-over intervals in the longitudinal direction
It was concluded that LV relaxation abnormalities in patients with systemic hypertension are characterized by abnormal systolic stretch in longitudinal direction and repolarization abnormalities which account for dyssynchronous onset of LV segmental relaxation.
This abstract is the basis for the first professional presentation to the medical community by Heart Test Laboratories.
It also represents an exceedingly important contribution to the acceptance of the MyoVista™ as an important community screening tool. The study will be presented by Dr. Sengupta and his colleagues from the University of California this June at the annual convention of the American Society of Echocardiography in Montreal Canada.
