Forecasting risk analysis of detection for carotid artery stenosis based on serum levels grading of lipoprotein (a)

Aim of the study: to assess the relationship between Lp(a) serum levels grading and carotid artery stenosis (CAS). The Duplex Registry database was used for this study. CAS was verified by duplex scanning in the presence of an atherosclerotic plaque (AP), stenosing the lumen of the carotid artery (CA) by 20 % or more. Patients who underwent a blood test for Lp(a) and the results were entered into the registry database were selected for this study. The immunoturbidimetric method was used to determine the serum level of Lp(a) (mg/dl). Data from 51 patients (66.6 % men) were included in the final analysis: median age 49.0 [46.0; 59], total cholesterol (TC) 5.93 [5.13; 6.56], Lp(a) 26.5 [14.2; 76.0]. Spearman rank correlation analysis showed the presence of significant relationships (p
