Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Background: Many studies have shown that metabolic syndrome is accompanied by an increase in arterial stiffness. In connection therewith, early detection of an increase in arterial stiffness in patients with metabolic syndrome can help to prevent cardiovascular complications. Aim: To determine the relationship between arterial stiffness parameters such as cfPWV and CAVI with carotid atherosclerosis indicators (intima-media thickness, carotid plaque presence) in patients with metabolic syndrome. Material and methods: The study included 100 patients at the age of 40-70 years: 45 men and 55 women (56.54±8.98 years). Subjects were divided into 2 groups: 1st - 42 patients with metabolic syndrome; 2nd - 58 patients without metabolic syndrome. The arterial stiffness parameters such as CAVI and cfPWV were calculated. In the analysis we used threshold values recommended by manufacturers and European expert consensus document on arterial stiffness: for CAVI – <8, for cfPWV – ≤10 m/c). Duplex scanning carotid arteries was performed to evaluate the “intima-media thickness” and carotid plaque presence. Results: In the group with metabolic syndrome the CAVI is significantly associated with the indicators of carotid atherosclerosis: intima-media thickness (OR=4.94 95%; CI: 1.49-3.80; p=0.047), carotid plaque presence (OR=3.06; 95% CI: 1.42-2.28; p=0.065). But statistically significant associations of cfPWV with indicators of carotid atherosclerosis were not obtained (p>0.05). In the group without metabolic syndrome none of the arterial stiffness parameters (CAVI, cfPWV) statistically significantly correlated with any of the carotid atherosclerosis indicators (p>0.05). Conclusion: The CAVI parameter, in contrast to the cfPWV, statistically significantly correlated with indicators of carotid atherosclerosis in patients with metabolic syndrome. In this connection, this parameter can be used to identify signs of not only increased arterial stiffness but also to determine subclinical signs of carotid atherosclerosis in patients with metabolic syndrome.
