Relative Risk Chart Score for the Assessment of the Cardiovascular Risk in Young Patients with Ankylosing Spondylitis

Abstract EN

Objective.

To determine if the use of the relative risk (RR) chart score may help to identify young ankylosing spondylitis (AS) patients at high risk of cardiovascular (CV) disease.

Methods.

73 AS patients younger than 50 years were assessed.

CV risk was calculated according to the total cholesterol systematic coronary risk evaluation (TC-SCORE) and the RR chart score.

C-reactive protein (CRP) value at disease diagnosis and carotid ultrasound data were also analyzed.

Results.

Twenty (27.4%) patients exhibited carotid plaques being classified into the category of very high CV risk.

None of them was found to have a high/very high TC-SCORE.

CRP > 3 mg/L at disease diagnosis was associated with the presence of carotid plaques (odds ratio 5.66, p=0.03).

Whereas only 5 (14.2%) of the 35 patients with RR = 1 had carotid plaques, 15 (39.5%) of 38 with RR > 1 showed plaques.

A model that included the performance of carotid US in patients with RR > 1 who had CRP > 3 mg/L allowed us to identify 60% of very high risk patients, with a specificity of 77.4%.

Conclusions.

RR chart score assessment may help to identify young AS patients at high risk of CV disease.
