Plasma angiotensin II levels in African hypertensives

Plasma angiotesin II levels were measured by immunoassay in twenty-seven Zulus with raised arterial pressures. Angiotensin levels were higher in patients with malignant than benign essential hypertension, mean values being 260.2 and 90.7 mumicrogram/ml with stanard deviations of 119.4 and 25.1 respectively (P = less than 0.0005).
