Abstract

OBJECTIVES:
A high prevalence of cardiovascular disease (CVD), not fully explained by the prevalence of traditional risk factors only, is reported in patients with idiopathic inflammatory myopathies (IIMs). Thus, we investigated if novel markers of CVD risk, like carotid diameter and advanced glycated end products, can better predict increased CVD risk in IIM patients.
METHODS:
We studied 43 consecutive patients diagnosed with IIM. All the patients underwent a clinical and laboratory evaluation of cardiovascular risk factors and characterisation of myositis disease activity. Non-invasive instrumental examinations performed included the measurement of carotid parameters (intima-media thickness, IMT and mean arterial diameter, mAD) by ultrasonic techniques, advanced glycation end-product accumulation in the skin by autofluorescence (AF) and body composition by bioelectrical impedance analysis. The parameters were compared to those measured in 29 controls, with similar mean age, BMI, blood pressure and smoking habits.
RESULTS:
IIM patients showed normal carotid IMT and distensibility, but higher carotid mAD (p=0.012), higher skin AF (p<0.001), lower fat free mass (p=0.036) and increased waist circumference compared to controls. A significant correlation was observed among AF and mAD (rho=0.317 p<0.05), carotid distension (rho=0.391 p=0.036) and IMT (rho=0.627 p<0.001).
CONCLUSIONS:
Abnormalities of the studied parameters suggest a higher risk of CV disease in IIM patients independent of disease activity. In this population, a thorough assessment of CV risk is recommended also in absence of overt CV disease during the clinical evaluation.
