METHOD FOR EARLY DIAGNOSTICS OF PROGRESSING NEPHROPATHY IN PATIENTS WITH ARTERIAL HYPERTENSION OF1ST DEGREE Russian patent published in 2017 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: doppler study is conducted, for which an ultrasonic sensor with an insonation frequency of 20 MHz is placed on the area of the nail roller of the third finger and a Dopplerogram is recorded. The linear velocity of the blood flow is measured at rest and after cold testing, the maximum systolic velocity is measured along the curve of the average Vas rate before and after testing. When a paradoxical reaction of the microcirculatory bed to the test is revealed, which manifests itself in a blood flow change in by more than 47%, rapid progression of hypertensive nephropathy is determined.

EFFECT: method provides early diagnosis of kidney damage in patients with arterial hypertension due to detection of endothelial dysfunction.
