Abstract

Low-renin hypertension (LRH) is characterized by hypertension accompanied by low serum renin levels. LRH is a spectrum, including low-renin essential hypertension (LREH), primary hyperaldosteronism, and several acquired or familial secondary forms. Here, we present a case of LRH. A 57-year-old female with resistant hypertension on multiple antihypertensive medications presented for blood pressure management. Workup for secondary causes of hypertension revealed low renin levels with normal aldosterone. The patient was initiated on spironolactone and responded quickly with normal blood pressure on a follow-up visit. LRH is an under-recognized etiology for uncontrolled hypertension. It can be secondary to several different causes. Although treatment of LREH is essentially the same as regular patients, these patients tend to respond well to sodium-volume-depleting diuretics, mineralocorticoid receptor blockers, and epithelial sodium channels (ENaC) blockers.
