Evaluation of cardiovascular changes in adolescents with mild essential hypertension by echocardiography and duplex ultrasonography

ABSTRACT

The aim of this research was to assess the cardiac as well as the vascular changes in adolescents with mild essential hypertension by echocardiography and duplex ultrasonographic technique of both carotid arteries. Forty-seven male patients with mild essential hypertension were chosen for the study. Sixteen male normotensive subjects in the same age group were taken as controls. The echocardiographic data showed that isovolumic relaxation time, posterior wall thickness at diastole, muscle mass and muscle mass index were significantly increased in hypertensive group; while, Ef%, Fs%, MVCF, stroke volume, stroke volume index, cardiac output, cardiac output index, E- F-slope, interventricular septal thickness at diastole, aortic root and left atrium dimensions insignificantly changed. Duplex data of both carotid arteries showed that intimal-medical thickness significantly increased, while pulsatility index insignificantly increased in hypertensive group
