Problems in the diagnosis of secondary arterial hypertension of adrenal origin

Abstract

Primary hyperaldosteronism is the leading cause of secondary arterial hypertension of adrenal origin. Its prevalence is underestimated. This leads to late diagnosis, although a timely diagnosis can achieve a complete cure for the patient, ensure control of blood pressure and avoid the development of complications. The article discusses the prevalence of primary hyperaldosteronism, its etiology and pathogenesis, the mechanisms of formation of autonomous secretion of aldosterone, including with the combined production of cortisol. The main clinical effects of aldosterone hypersecretion, its role in the formation of complications in the cardiovascular system and metabolic control are discussed. The assessment of the main clinical effects of aldosterone hypersecretion and its role in the formation of complications from the cardiovascular system and metabolic control is given. The authors remind about risk groups in which screening should be carried out, about the stages of a diagnostic search for suspected primary hyperaldosteronism. For the primary test, a preliminary assessment of the level of plasma potassium is necessary, and if hypokalemia is detected, its correction. If the result of the primary test is false negative, retesting will be carried out with the transfer of patients to antihypertensive drugs with minimal effect on the renin-angiotensinaldosterone system. It is important to remember that confirmatory sodium loading tests are contraindicated in some patients. Computed tomography with contrast in combination with selective venous blood sampling in patients are the most significant methods for the topical diagnosis of primary hyperaldosteronism. The choice of treatment method and its effectiveness depend on their results.
