Comparative assessment of the signs of instability of atherosclerotic plaques in the carotid arteries in elderly patients with acute coronary syndrome with duplex scanning and computed tomography angiography

Aim . To study the signs of instability atherosclerotic plaques (ASP) in carotid arteries elderly patients with acute coronary syndrome (ACS) comparative aspect duplex ultrasound scanning (DUS) and computed tomography angiography (CT). M aterial methods. 27 ACS (75 years over) were included study. The ASP assessed according to DUS CT. Results detected 85,7%, CT — 84,6%. following CT: presence irregular plaque surface including ulceration 6,4 11,6% (p=0,021), positive remodeling 3,8 3,8% (p=0,998), local calcification 23 25,9% (p=0,536), heterogenous structure 55,1 46,8% (p=0,045), hypoechogenic component low-density areas 11,5 (p= 0,998). correlation analysis showed high comparability (K=0,624, p=0,02), (K=1, p<0,001), (K=0,858, (K=0,754, p<0,001). Conclusion found definition arteries. It is possible use as a routine method for assessing atherosclerosis this group, which can reduce risk complications during CT, shorten examination time, minimize economic costs.
