866-6 Age-related left ventricular function alterations in mice: A tissue doppler imaging study

Changes in the parameters of left ventricular diastolic function according to age on tissue Doppler imaging.

OBJECTIVE To determine the correlation between diastolic velocities on tissue Doppler imaging and age in a sample of healthy adults and to correlate age with the velocities of transmitral and pulmonary vein flows. METHODS Echocardiographic assessment of 51 healthy individuals, whose ages ranged from 21 to 69 years. The diastolic myocardial velocities were recorded on tissue Doppler imaging. T...

Evaluation of left ventricular function in obese children without hypertension by a tissue Doppler imaging study

Background The prevalence of obesity is increasing worldwide. Obese children without hypertension are becoming an important health challenge. Aims Complications of obesity in adults are well established, but in obese children, cardiac dysfunction has not been reported clinically. Settings and Design The present crosssectional study investigates subclinical systolic and diastolic dysfunction...

The significance of tissue doppler imaging in the diagnosis of left ventricular diastolic function

Objective: Using tissue Doppler imaging (Tissue doppler imaging, TDI) to detect mitral annulus velocity in patients with hypertension and compared with blood flow Doppler method. This research was aimed to explore the new method to evaluate left ventricular diastolic function in patients with hypertension. Methods: One hundred of hypertensive patients in our hospital were enrolled from March 20...

Characterisation of left ventricular function by tissue Doppler imaging technique in newly diagnosed, untreated hypertensive subjects

BACKGROUND Hypertension results in structural and functional changes in the heart. Early detection of abnormalities of cardiac structure and function is important in the assessment and treatment of hypertensive subjects. The aim of this study was to evaluate the utility of the tissue Doppler echocardiographic technique in characterising diastolic and systolic functions in untreated native black...
