elevated renin hypertension

Hypertension associated with elevated renin activity typically presents with increased blood pressure and a corresponding rise in plasma renin activity levels. This form of hypertension may be linked to renal dysfunction, renal artery stenosis, or other disorders of the endocrine system.

Upon detailed examination, the increase in renin activity could stem from a reduction in renal blood flow, prompting the juxtaglomerular cells to secrete more renin, which in turn activates the renin-angiotensin system. This activation leads to systemic arteriolar constriction and a subsequent rise in blood pressure. Conditions such as renal artery stenosis and primary aldosteronism can also result in heightened renin activity. For diagnosis, it is essential to measure blood pressure and assess plasma renin activity and electrolyte levels to rule out other potential causes of secondary hypertension.

Patients with hypertension and elevated renin activity should focus on a low-sodium diet, engage in moderate physical activity, maintain a positive mental state, and regularly monitor their blood pressure and kidney function. Treatment should involve the use of antihypertensive medications under a physician's supervision, rather than self-medicating without guidance. If blood pressure remains uncontrolled or if renal damage is detected, it is crucial to seek medical attention promptly to revise the treatment strategy.
