Assessment of Cardiac Diastolic Dysfunction in Normotensive Type 2 Diabetic Patients with preserved Cardiac Systolic Function in Various Age Groups

Transmitral flow velocity patterns obtained by pulsed Doppler echocardiography are widely used to non invasively evaluate LV diastolic function. In many circumstances, however, the interpretation of these indices is difficult because they respond to different physiological variables other than ventricular relaxation such as heart rate, and most importantly loading conditions.Recently, tissue Doppler imaging has emerged as a new non invasive imaging modality that allows direct measurement of myocardial velocities throughout the cardiac cycle. The aim of this study is to evaluate LV diastolic function through assessing the velocity of mitral annulus motion during diastole by tissue Doppler imagingIn this study ,60 patients in different age groups with history of type II diabetes mellitus were classified according to the age into the followingGroup A :it include 15 patients in their thirtiesGroup B :it include 15 patients in their fortiesGroup C :it include 15 patients in their fiftiesGroup D :it include 15 patients in their sixties.
