Assessment of diastolic reserve in hypertensive patients by dobutamine stress Doppler tissue imaging

Many hypertensive patients are symptomatic mainly with exercise, because of the rise in filling pressures. Therefore, it is useful to evaluate left ventricular filling pressure with exercise. The study aims to determine the role of dobutamine stress echocardiography in assessment of diastolic reserv...

Description
Summary:Many hypertensive patients are symptomatic mainly with exercise, because of the rise in filling pressures. Therefore, it is useful to evaluate left ventricular filling pressure with exercise. The study aims to determine the role of dobutamine stress echocardiography in assessment of diastolic reserve in hypertensive patients with normal ejection fraction. 30 Hypertensive patients (53.8±4.1years) and 20 sex and age-matched healthy controls (51.9±9.7years) were recruited. Patients with coronary artery disease, significant valvular disease, hypertrophic cardiomyopathy, left ventricular systolic dysfunction (EF
