The echogenicity of atherosclerotic plaques in the carotid arteries in patients with acute coronary syndrome and its effect on the prognosis of cardiovascular events

Some studies have shown that the echogenicity of atherosclerotic plaques (AP) in the carotid arteries (CA) plays an important role in evaluating the risk of cardiovascular events (CVE). The method of calculating the Gray Scale Median (GSM) is currently used to quantify the echogenicity of the CA plaque.Aim. To study GSM assessment of CA AP in patients with acute coronary syndrome (ACS) and the effect of GSM on the prognosis of CVE.Material and methods. We examined 143 patients with ACS (32-83 years old). Duplex scanning was performed on “Philips iU 22” for 1-3 days after hospitalization, the second — in 1-1,5 years. The echogenicity of the detected APs was assessed on a gray scale using a modified GSM method at the Multivox workstation.Results. We analyzed 378 CA AP in patients with ACS. The GSM analysis on the first and repeated surveys showed a significant increase in the average GSM by 2,2% (p
