Abstract

Introduction: Resistant arterial hypertension can be of primary or secondary origin. The investigation of secondary arterial hypertension should be reserved for suggestive cases, however, its identification is essential, as the treatment of the cause improves blood pressure control and enables cure. Objectives: To present the clinical case of an individual who despite the presence of factors suggestive of secondary arterial hypertension, maintained inadequate control of blood pressure levels for 35 years. After correct diagnosis and treatment, blood pressure levels normalized. Methods: The individual was referred to an outpatient clinic specializing in resistant arterial hypertension and submitted to the flowchart of investigation of secondary arterial hypertension: plasma aldosterone level; plasma renin activity (ARP); computed tomography (CT) of the abdomen; saline overload and captopril suppression tests; ambulatory blood pressure measurement; and teste to search for target organ damage. Results: Plasma aldosterone = 15.5 ng/dL, suppressed ARP and aldosterone/ARP ratio = 51.6. CT: nodule on the lateral stalk of the left adrenal measuring 10x9mm, compatible with adenoma. Aldosterone after saline overload = 20.5 ng/dL. Positive captopril suppression test. Renal function and normal microalbuminuria. Doppler echocardiogram: left chamber enlargement. Once the diagnosis of primary hyperaldosteronism was established, spironolactone was started with improvement in blood pressure control. He was then submitted to adenoma resection surgery, reaching his blood pressure goals with a single drug. Conclusion: It is important to recognize situations in which secondary causes of hypertension should be investigated for adequate treatment, avoiding chronic complications of uncontrolled hypertension.
