Ways of improving the diagnosis and prognosis in vasorenal hypertension

: Atherosclerosis, aorto-arteritis and fibromuscular dysplasia are the most common causes of vasorenal hypertension. Determination of plasma renin activity is a valuable diagnostic test at early stages of vasorenal hypertension. HLA studies demonstrated significantly elevated antigens B8 and B12 in patients with essential hypertension, and antigen A9 in patients with affected renal arteries. These findings may expand the possibilities of differential diagnosis for the selection of patients, eligible for angiographic investigation. A less than three-years duration of the disease in the presence of high plasma renin activity is a favorable prognostic criterion.
