Left ventricular morphology and function in mild to moderate essential hypertension.

150 males with mild to moderate essential hypertension [EH] were examined echocardiographically and the findings in the left ventricle [LV] were compared with those in 20 normotensive men. Increased LV wall thickness and LV mass was found in 81% and 67% of hypertensives respectively in contrast with a complete absence of LV hypertrophy in normotensives. The former showed also a tendency to the concentric type hypertrophy, which can be considered a characteristic feature of the 2nd stage [WHO] EH.

Distribution of blood pressure in children and adolescents.

Casual blood pressures were evaluated in 13 475 children and adolescents of elementary and secondary schools in the district of Prague 4. Measurements in an unselected children population determined mean systolic and diastolic pressures and standard deviations in different age groups. Children with elevated blood pressure were selected according to arbitrarily chosen criteria.
