Age dependency of left ventricular and left atrial diastolic variables assessed with acoustic quantification

echocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction

background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy   (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction   is associated with lvh and inappropriate lvm. methods: one hundred   and twenty five uncomplicated hypertensi...

Hemodynamic Variables Affecting the Relation between Mean Left Atrial and Left Ventricular End-diastolic Pressures.

• Changes of pressure in the atrium have two direct and important circulatory consequences. The first is that a change of mean atrial pressure alters the central pressure level "which must be exceeded by blood returning from the venous system. The second is that a change of atrial pressure will influence the rate of ventricular filling and ventricular end-diastolic pressure. The significance of...

Left ventricular diastolic dysfunction in atrial fibrillation

LEFT 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...

Left ventricular diastolic function in essential hypertensive patients: influence of age and left ventricular geometry.

PURPOSE To evaluate diastolic dysfunction (DD) in essential hypertension and the influence of age and cardiac geometry on this parameter. METHODS Four hundred sixty essential hypertensive patients (HT) underwent Doppler echocardiography to obtain E/A wave ratio (E/A), atrial deceleration time (ADT), and isovolumetric relaxation time (IRT). All patients were grouped according to cardiac geomet...
