It would be nice if ACE inhibitors also supressed the release of renin, but they don't. Many of my classmates have problems with stuff like this. What causes an increase in renin? What do high renin levels mean? However, in rare cases the renin elevation can be secondary to renal artery stenosis or even more rarely due to a tumor that secretes renin. The renin-angiotensin system, working together with the kidneys, is a vitally . In the blood, renin acts on a protein known as angiotensinogen, resulting in the release of angiotensin I. The higher renin levels in turn cause even greater depletion of plasma angiotensinogen thereby inducing even higher rates of renin secretion.
Controlling resistant hypertension | Stroke and Vascular Neurology Should We Routinely Measure Renin Levels - Medscape This lowers blood sodium levels and decreases the amount of fluid in the blood (which lowers blood volume and pressure), which in turn stimulates renin production by the kidney. Treatment of Primary Hyperaldosteronism Medium-/high-renin hypertension responds very well to agents such as angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and -blockers, all of which block plasma renin activity, although addition of a sodium-volume depleting drug is sometimes required to control blood pressure.
Factors affecting the aldosterone/renin ratio - PubMed Renin suppression is due to aldosterone-dependent sodium retention and mild extracellular volume expansion.

Diagnostic imaging is employed to identify the source of excessive renin production. Certain health conditions may also causes changes to renin levels. Renin maintains blood pressure through vasoconstriction when there is inadequate salt to maintain volume. Secondary hyperaldosteronism occurs when the kidney produces too much renin. This leads to decreased circulating blood volume, which stimulates renin production [ 24 ].
