Normotensive Subjects

To determine whether urinary sodium excretion (a rather rough estimate of sodium intake) can influence left ventricular mass independently of arterial pressure, 91 untreated subjects with essential hypertension and 50 normotensive subjects of similar age were studied. Left ventricular mass index (M-mode echocardiography) was positively correlated with urinary sodium excretion in hypertensive (r = 0.22, P less than 0.01) as well as normotensive subjects (r = 0.22, P less than 0.05), and systolic arterial pressure was correlated only in hypertensive subjects (r = 0.23, P less than 0.01). When hypertensive subjects were divided into groups with appropriate or inappropriate left ventricular mass by reference to a theoretical optimal left ventricular mass for each subject's level of systolic arterial pressure, left ventricular mass was appropriate in 68% and inappropriate in 32% of subjects. Urinary sodium excretion was higher in subjects with inappropriate left ventricular mass compared with those with appropriate left ventricular mass. In conclusion, sodium excretion may be an important modulator of the influence of arterial pressure on the left ventricle in normotensive subjects and subjects with essential hypertension.

Plasma Renin Concentration

1. The effect of intravenous loading with 500 ml of sodium chloride solution (50 g/l) on plasma renin concentration, plasma aldosterone concentration, urinary sodium excretion and mean blood pressure was studied in 15 young patients with mild essential hypertension and 10 healthy normotensive control subjects. 2. Plasma renin concentration and plasma aldosterone concentration were suppressed to the same degree during loading in both the hypertensive and normotensive groups. Urinary sodium excretion was significantly higher in the hypertensive patients than in the normotensive subjects. Mean blood pressure increased slightly in both groups. 3. Plasma renin concentration and plasma aldosterone concentration were significantly correlated in both groups before sodium loading. The increase in urinary sodium excretion was significantly correlated to the suppression of plasma aldosterone concentration in the hypertensive, but not in the normotensive, group. No correlation was found between changes in urinary sodium excretion and changes in plasma renin concentration or mean blood pressure. 4. The results indicate that the suppressibility of the renin—aldosterone system by hyperosmotic sodium chloride solution is normal in young patients with mild essential hypertension. It is suggested that the changes in plasma aldosterone concentration induced by sodium loading might be involved in the regulation of exaggerated natriuresis in essential hypertension.
