Left Atrial Strain as a Predictor of Early Left Atrial Dysfunction in Well Controlled Hypertension with Normal Left Atrial Size [PDF]

Zagazig University Medical Journal
Background: Lately, there has been a growing focus on structural and functional changes in the left atrium (LA), which may be early signs of heart damage brought on by hypertension (HTN).

Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 11, Page 2205-2220, November 2026.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, Volume 111, Issue 11, Page 5094-5104, 1 November 2026.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Speckle tracking Echocardiography is a sensitive tool for the detection of myocardial ischemia : A pilot study from the catheterization laboratory during percutaneous coronary intervention

, 2007
Analysis of rotational myocardial motion has been reported to be a sensitive index of myocardial ischemia. In this study, circumferential and radial myocardial strain and displacement was monitored during angioplasty balloon-induced myocardial ischemia ...
