Aim of study: To study changes of left ventricular diastolic function and morphology in adroid obesity patients by standard doppler echocardiography and tissue doppler imaging. In that, evaluate the role of Tissue Doppler Imaging(TDI) in studying the left ventricular diastolic function. Patients and methods: We studied 30 obese patients (12 men have waist circumference ≥90cm and 18 women have waist circumference ≥80 cm), mean age 49.33±7.16 years , non hypertension and non diabetic, by conventional doppler echocardiography and tissue doppler imaging. Results: Mean BMI of obese patients: 25,35±2,87kg/m2. Waist circumference: 91,03±6,29cm. Left ventricular end- diastolic diameter: 45,9±4,05mm. Left ventricular mass: 143,47±35,56g. Left ventricular mass index: 85,69±19,55g/m2. Left atrial diameter: 36,34±4,33mm. The early diastolic wave of the transmitral flow velocity(E): 75,2±17,5 cm/s; the atrial systolic wave of the transmitral flow velocity: 76,2±16,5cm/s; the ratio of early diastolic wave to atrial systolic wave of the transmitral flow velocity: 0,99±0,29. The early diastolic wave of mitral annu-lus using pulsed TDI(Em): 12,1±3,3cm/s. The atrial systolic wave of mitral annu-lus using pulsed TDI(Am): 12,7±2,9cm/s. E to Em wave ratio: 6,76±2,19. Conclusion: In adroid obesity patients, the morphology of diastolic left ventricular changes earlier than the one’s function.
