On the issue of critical arterial stenosis

Abstract

Cardiovascular disease (CVD) is the leading cause of death worldwide. The main contribution to the structure of mortality from CVD is made by atherosclerosis. Indications for surgical treatment of patients with diseases caused by atherosclerotic lesions of the arteries are set taking into account the degree of their stenosis. Angiography has been considered the gold standard for screening patients with CVD for many years. Numerous studies carried out over the past several decades have revealed the weak side of this method in assessing the significance of borderline stenosis. Therefore, to analyze such changes, functional tests were introduced to clarify the indications for surgical intervention. Currently, criteria for the significance of stenosis of the iliac, renal and coronary arteries have been determined. The significance of stenosis of the arteries supplying the brain and intestines is still a matter of debate and requires further study.
