Abstract

Abstract : Objective: The present study aims to identify the cardiovascular risk associated with chronic inflammation and disease activity in patients with ankylosing spondylitis (AS) using noninvasive ultrasonographic radiofrequency data technology. Methods: In this study, a total of 87 participants, 38 patients with AS and 49 healthy controls, were evaluated by Doppler ultrasonography. Intima‐media thickness (IMT) and arterial stiffness were measured from the bilateral common carotid artery using the radiofrequency method. Results: No statistically significant difference was found between the AS patients and healthy controls concerning the right common carotid artery, left common carotid artery, IMT, distensibility coefficient, elasticity coefficient, α and β stiffness indexes, and pulse wave velocities ( P > .05). The symptom duration of the AS patients had a positive correlation that was moderate and was detected with the α stiffness index and pulse wave velocity ( P < .05). The duration of diagnosis and treatment of the AS patients had a positive correlation that was moderate, was detected with the α stiffness index, the β stiffness index, and pulse wave velocity ( P < .05). The mean IMT and elasticity coefficient values of the AS patients whose Bath Ankylosing Spondylitis Disease Activity Index score was 4 and above, were substantially higher than the values in the patients with scores lower than 4 ( P = .038 and P = .33, respectively). Conclusions: Subclinical atherosclerosis is not accelerated in AS patients with low disease activity, although insufficiently controlled disease activity may result in increased carotid IMT and atheromatosis. Radiofrequency data technology provides a noninvasive method for accurately and quantitatively demonstrating CCA‐IMT elevation and the decrease in vascular elasticity in patients with AS.
