In suspected secondary hypertension in a young patient with sudden severe HTN, which finding would support a secondary cause?

• A. Regular pulses
• B. Abdominal bruits
• C. Low potassium (hyperaldosteronism)
• D. Pheochromocytoma

Answer: (B)

In a young patient with sudden, severe hypertension, a clue that points toward a secondary cause is a finding that signals renal artery compromise. An abdominal bruit reflects turbulent blood flow through a narrowed renal artery, most commonly from fibromuscular dysplasia in younger individuals. ThisRenovascular hypertension increases renin release, activating the RAAS and raising blood pressure, which is a classic pathophysiology of secondary hypertension in this demographic. Other choices don’t fit as neatly. Regular pulses don’t indicate a problem with renal perfusion. Pheochromocytoma can cause severe HTN but often presents with episodic symptoms like headaches, sweating, and tachycardia rather than a localized abdominal sound. Low potassium suggests hyperaldosteronism, another secondary cause, but it’s not the standout clue for renovascular disease in this clinical scenario.
