COMPARATIVE ANALYSIS OF THE DETECTION FREQUENCY OF CAROTID PLAQUE IN INDIVIDUALS WITH LOW CARDIOVASCULAR RISK
Aim: To compare the detection frequency of carotid plaque in man and woman of different age groups and with low cardiovascular risk according to SCORE scale. Material and methods: The study included 300 persons: 180 woman (50,8±0,37 y.) and 120 man (49,8±0,76 y.) with low cardiovascular risk according to SCORE scale. Duplex scanning carotid arteries (DSCA) was performed on a Vivid 9 (JA, USA) with linear-array 12-MHz transducer to evaluate the presence of plaques in the carotid arteries (carotid plaque presence). It was used the scanning in the B-mode of the common carotid artery (CCA) from the mouth to the area of bifurcation, internal (ICA) and external (ECA) carotid arteries in cross and longitudinal sections; total 6 position. Results: Totally the carotid plaque were detected in 192 individuals (64%): 108 woman (60%) and 84 man (70%). The most of them had 20-30% arterial stenosis carotid plaque. The number of persons with carotid plaque was increased in man at the age of 35 y. and in woman - older than 40 y. Herewith the 93% of the man at the age older than 50y had carotid plaque, but 88% of the woman had carotid plaque at the age older than 65 y. Furthermore almost all man at the age older than 40 y. had 3 and more carotid plaques. Conclusion: The individuals with low cardiovascular risk according to SCORE scale had a high level of carotid plaque presence. The frequency detection of carotid atherosclerosis is higher in man than in woman.
