Relationship between LA Strain by 2D Speckle Tracking and LV Diastolic Function in Patient with Different Grades of LV Diastolic Dysfunction

Subclinical LV Dysfunction Detection Using Speckle Tracking Echocardiography in Hypertensive Patients with Preserved LV Ejection Fraction

BACKGROUND Early detection of subclinical left ventricular (LV) systolic dysfunction in hypertensive patients is important for the prevention of progression of hypertensive heart disease. METHODS We studied 60 hypertensive patients (age ranged from 21 to 49 years, the duration of hypertension ranged from 1 to 18 years) and 30 healthy controls, all had preserved left ventricular ejection fract...

Evaluation of LV diastolic function from color M-mode echocardiography.

OBJECTIVES this study evaluated early diastolic filling dynamics using a semiautomated objective analysis of filling velocities obtained from color M-mode echocardiography. BACKGROUND diastolic function can be evaluated from color M-mode echocardiography by measuring the early diastolic flow propagation velocity (Vp) from the slope of a single linear approximation of an isovelocity contour. H...

Diastolic Function During Development and Correction of Chronic LV Volume Overload Produced by Mitral Regurgitation

Background. Mitral regurgitation (MR) causes an augmentation in left ventricular (LV) diastolic function, increasing early diastolic filling rate and decreasing LV stiffness. Whether these changes in diastolic function persist, return to normal, or become abnormal after mitral valve replacement (MVR) is unknown. Methods and Results. Simultaneous LV echocardiography and catheterization studies w...
