Secondary Hypertension

Prioritize a secondary-hypertension evaluation in patients younger than 40 years, those with sudden worsening or accelerated hypertension, and those with blood pressure that responds poorly to treatment. Accelerated hypertension with blood pressure above 180/110 mm Hg plus papilledema and/or retinal hemorrhage requires urgent assessment rather than deferred outpatient etiologic testing. nice org uk+1nice org ukNATIONAL INSTITUTE FOR HEALTH AND CLINICAL ...AHA JournalsPrevalence and Risk Factors for Secondary Hypertension ...

For severe blood-pressure elevation, first determine whether acute end-organ damage is present and obtain renal function, electrolytes, bicarbonate, glucose, HbA1c, lipids, complete blood count, clotting studies when microangiopathic hemolytic anemia or disseminated intravascular coagulation is a concern, urine microscopy, urine albumin-to-creatinine ratio, and thyroid function tests.

During a hypertensive crisis, collect endocrine studies selectively and interpret them cautiously. Pressure natriuresis with volume depletion can produce secondary hyperaldosteronism, while medications, pain, anxiety, subarachnoid hemorrhage-related stress, heart failure, and kidney failure can make renin, aldosterone, and metanephrine results unreliable; complete elective secondary-cause testing after stabilization when possible.

Perform a structured reconciliation of prescription drugs, over-the-counter agents, supplements, recreational drugs, alcohol, and dietary exposures. Important causes include NSAIDs including COX-2 inhibitors, sympathomimetic decongestants and anorectics, cocaine, amphetamines, oral contraceptive hormones, adrenal steroid hormones, erythropoietin, cyclosporine, tacrolimus, licorice-containing products, and supplements containing ginseng, yohimbine, ma huang, or bitter orange. jaccjaccResistant Hypertension: An Overview of Evaluation and Treatment

Assess sodium exposure, extracellular-volume status, kidney disease, and adequacy of diuretic therapy. Excess sodium intake, volume retention from kidney disease, and inadequate diuresis can maintain apparent resistant hypertension and should be corrected in parallel with etiologic testing. jaccjaccResistant Hypertension: An Overview of Evaluation and Treatment

Actively assess obesity, diabetes, and obstructive sleep apnea in resistant hypertension. Obstructive sleep apnea is a common secondary cause associated with resistant hypertension, and its coexistence does not exclude renal, renovascular, or endocrine causes.

Renal parenchymal disease is the most common medical cause of secondary hypertension in resistant-hypertension evaluations. Abnormal renal function, urine microscopy, or urine albumin-to-creatinine ratio should direct the next diagnostic step toward kidney disease rather than an isolated endocrine workup.

Consider renovascular disease when the overall clinical setting suggests renal arterial disease, particularly in resistant hypertension. Renal artery stenosis is among the common identifiable causes in this setting; renal artery and kidney imaging should be directed by clinical suspicion rather than used as a universal screen.

Primary aldosteronism is a high-priority, treatment-changing diagnosis. It occurs in approximately 5% to 10% of all hypertension and about 20% of resistant hypertension, and the 2025 AHA/ACC guideline recommends screening adults with resistant hypertension regardless of whether hypokalemia is present.

Use the plasma aldosterone-to-renin ratio as the screening test for primary aldosteronism in patients with hypertension, including those without hypokalemia. A positive screen generally requires confirmation of inappropriate aldosterone secretion with a suppression test such as saline infusion or fludrocortisone suppression before subtype-directed management.

For primary aldosteronism, treatment selection follows subtype. Laparoscopic adrenalectomy is the preferred definitive therapy for unilateral aldosterone-producing adenoma and often cures or markedly improves hypertension; bilateral disease is treated medically with mineralocorticoid receptor antagonists. The Endocrine Society suggests spironolactone over alternative medical therapy for patients receiving primary-aldosteronism-specific treatment.

Use specialist referral early for suspected primary aldosteronism, pheochromocytoma/paraganglioma, Cushing syndrome, or renovascular hypertension because testing and treatment require technical interpretation and, in selected cases, specialized procedures.

Follow treatment response using blood pressure, serum potassium when mineralocorticoid excess or antagonism is relevant, and kidney function during management of kidney disease or mineralocorticoid receptor antagonist therapy. In primary aldosteronism, reassess blood-pressure control and biochemical abnormalities after medical therapy or adrenalectomy because cure is not universal even after treatment of unilateral disease.
