چکیده
Medicine, University of Alabama at Birmingham, Birmingham, AL, USA Full list of author information is available at the end of the article Figure 1 Schematic diagram for calculating torsional hysteresis–the area within the systolic and diastolic arm of the normalized torsion volume (TV) curves (A), normalized TV curves for the two groups (B) and calculated torsional hysteresis (C). Torsion hysteresis is greater in the HTN vs. Control. *, P<0.001 vs. Control; Data points are expressed as mean±standard error. Schiros et al.

Left ventricular torsion shear angle volume analysis in patients with hypertension: a global approach for LV diastolic function
BACKGROUND Torsion shear angle φ is an important measure of left ventricular (LV) systolic and diastolic functions. Here we provide a novel index utilizing LV normalized torsion shear angle φ ^ volume V ^ loop to assess LV diastolic functional properties. We defined the area within φ ^ V ^ loop as torsion hysteresis area, and hypothesized that it may be an important global parameter of diastoli...

Background: Cardiovascular problems including arterial hypertension, coronary artery diseases, congestive heart failure are prevalent among chronic hemodialyzed patients. Ultrafiltration of hemodialyzed patient's serum, which culminating in intravascular volume reduction, is frequently used during hemodialysis. One of the restrictions of the echocardiographic evaluation of the diastolic heart f...
متن کاملLEFT VENTRICULAR DIASTOLIC ABNORMALITIES IN β-THALASSEMIA MAJOR WITH NORMAL SYSTOLIC FUNCTION
In order to identify left ventricular diastolic function in patients with betathalassemia major and normal systolic function by noninvasive M-mode and Doppler echocardiography, an analytic study was designed in a university hospital in Sari. We have studied 44 patients (23 men and 21 women), mean age 15.48±2.16 (range 12 to 20) and 43 age and sex matched control subjects. Peak flow velocit...
