Abstract
OBJECTIVES:
Takayasu's arteritis (TAK) is a chronic inflammatory large vessel vasculitis with a grim prognosis due to the excessive risk for cardiovascular (CV) diseases. Its diagnosis relies on radiographic imaging and its differentiation particularly from atherosclerosis could be challenging. Hypothesising that vascular morphology observed in TAK would be comparable to that found in type 2 diabetes mellitus (T2DM), a prototype for advanced atherosclerosis, we compared two disease groups using carotid artery B mode US and shear wave elastography (SWE).
METHODS:
A total of 72 patients with TAK (63F/9M; mean age: 42.7± 10.0 years) and 74 patients with T2DM (65F/9M; mean age: 50.2± 7.1 years) were studied. Intima-media thickness (IMT), outer diameter and arterial stiffness as assessed by SWE values were measured on the common carotid artery (CCA) and atherosclerotic plaques were recorded. Clinical characteristics, CV risk factors and previous history of CV diseases were determined. Framingham risk score was calculated.
RESUULTS: Patients with TAK exhibited significantly lower atherosclerotic risk but higher systolic blood pressure (BP) levels compared to those with T2DM. The mean values of CCA IMT, outer diameter, and stiffness were significantly elevated among patients with TAK compared to those with T2DM. Carotid artery plaques were evenly distributed between the study groups, but their anatomical localisation and composition differed significantly. While coronary artery disease (CAD) was more prevalent among T2DM patients, cerebrovascular diseases were more frequent among TAK patients.
CONCLUSIONS:
Our study revealed distinctive vascular alterations and atherosclerotic changes when compared to advanced atherosclerosis associated with T2DM. Apart from these, higher levels of systolic BP and significantly different distribution of CV diseases between TAK and T2DM also suggest that TAK should be handled with distinct assessment strategies than that employed in conventional atherosclerotic conditions.
