PREVALENCE OF ARTERIAL HYPERTENSION AMONG PEOPLE WITH A DEFINITE DIAGNOSIS OF PHEOCHROMOCYTOMA

Abstract

This article presents the results of a study of the prevalence of arterial hypertension among individuals with a reliably established diagnosis of pheochromocytoma, which is a benign, hormonally active neoplasm of the adrenal medulla or chromaffin outside the adrenal tissue. The results of instrumental methods of examination and treatment of patients with a diagnosis of pheochromocytoma, adrenal and outside adrenal localization with concomitant arterial hypertension and changes in laboratory parameters in the form of hypokalemia, elevated plasma aldosterone and reduced renin activity were studied. In total, 57 people took part in the study, of which 26 were men and 31 women aged from 21 to 54 years old. The study revealed that outside the adrenal localizati on of the neoplasm was accompanied by sustained hypertension, resistant to antihypertensive drugs. With the adrenal location of the pheochromocytoma, transient crises with associated autonomic disorders were more often observed. The radical surgical treatment of pheochromocytoma has led to a persistent normalization of blood pressure in most patients.
