Influence of Renin Levels on the Treatment of Essential Hypertension With Thiazide Diuretics

Arch Intern Med. 1987;147(6):1021-1025. doi:10.1001/archinte.1987.00370060017003
Abstract

• Initial plasma renin activity (PRA) was measured in 213 patients with untreated hypertension before beginning thiazide (chlorothiazide and hydrochlorothiazide) therapy alone to test whether patients with low-renin hypertension exhibited a greater response to diuretic therapy. Diastolic blood pressure response to treatment in the low, mid-range, and high PRA groups did not differ significantly (Δ diastolic blood pressure, -13.6±1.6, -11.6±1.5, and -10.8±2.6 mm Hg, respectively). Moreover, eight subjects with the highest PRA values exhibited the same magnitude of decrease in diastolic blood pressure as did the low PRA group (15.0±4.2 vs 13.6 ±1.6, respectively). This study thus provides no evidence for increased sensitivity to diuretic therapy among patients with low-renin essential hypertension.
