The Virtual Coronary Angiography Method

Abstract

This article is devoted to the development of a virtual coronary angiography method, a noninvasive method of evaluation of the state of the human coronary artery. Registration and processing of the signal of peripheral arterial blood pulsation against the background of a functional test with controlled respiration form the basis of the method. A mathematical model of the relationship between relative change in spectral evaluations of the variability of the cardiac rhythm and the degree of coronary-artery stenosis was developed. Clinical testing, which demonstrated the high efficiency of the proposed virtual coronary angiography method when examining patients with different states of coronary arteries, was conducted.
