METHOD FOR NON-INVASIVE DIAGNOSTICS OF CORONARY ATHEROSCLEROSIS USING VISUAL SCALE Russian patent published in 2021 - IPC A61B8/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly, to cardiology, and can be used for diagnostics of coronary atherosclerosis. Duplex scanning (DS) of the carotid arteries (CA), femoral arteries (FA) is performed, the maximum (max.) and average (avg.) degrees of stenosis in the examined arteries of the CA and FA territories are considered. The height of the atherosclerotic plaque protruding most strongly into the lumen of the vessel (max. ASP) is measured, diagnostic complexes (DC) are formed, including max. ASP, average (avg.) and maximum (max.) degrees of stenosis in the common carotid artery (CCA), in the area of bifurcation of the CCA, in the internal carotid artery (ICA), in the external carotid artery (ECA), in the common femoral artery (CFA), in the area of bifurcation of the CFA, in the superficial femoral artery (SFA), in the deep femoral artery (DFA) from both sides; according to the results of the examination, DCs are estimated in points and used to determine visual scales (VS) of CA and FA. At a VS_total of less than 2 points, atherosclerosis of the CA is assumed to be absent. At a VS_total of 2 to 4 points, subclinical atherosclerosis of the coronary arteries is diagnosed. At a VS_total exceeding 4 points, multivessel coronary artery damage is diagnosed.

EFFECT: method allows optimising the approach to patient management, including the decision to perform CAG, and to select an optimal approach to patient management.
