FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to nephrology and cardiology. Dopplerographic examination of renal arteries is carried out using a pharmacological test with captopril. Values of the basal indices of remodeling of renal vessels are determined before the captopril test (CT1) and after the sample (CT2). Further, the functional renal reserve (FRR) is calculated as the difference between the values CT1 and CT2. With an FPR value of less than 5 %, the absence of a renal reserve is diagnosed, which indicates the presence of subclinical hypertensive nephropathy.
EFFECT: method allows to diagnose disorders of renal blood flow in the preclinical stage of hypertensive nephropathy.
