Abstract
We undertook this study to identify predictors of arterial hypertension. We have studied 20 normotensive adolescents with hypertensive parents (SHT), who carry a high risk of becoming hypertensive later in life. These subjects were compared with a group of 20 .normotensive adolescents with normotensive parents (SNT) and a group of adolescent with borderline hypertension (BH). Control groups were matched for age and sex. We utilized echocardiography with all its different modalities to assess the morphological and function status of the heart in the different studied groups. The following morphologic indexes of cardiac hypertrophy (interventricular septal thickness, posterior wall thickness, left ventricular mass-and left ventricular mass index) were significantly higher in the SHT and BH groups than in the SNT group, but they remained within the normal ranges. Left ventricular ejection fraction (EF) and fractional shortening (FS%) were significantly higher in the BH group. No differences were observed. Some indexes of LV diastolic function (late A velocity and E/ A ratio transmitral flow) were significantly higher in the SHT and BH groups than in the SNT group, but they remained within the normal ranges. In conclusion, . diastolic impairment of LV function and echocardiographic increase in LVM and LVMI in normotensive young adults with family history . of hypertension is directly related to the risk of developing subsequent hypertension. So, these non-invasive simple parameters .might to used to identify predictors of arterial hypertension.
