OBJECTIVES
Despite the high prevalence of cardiovascular disease (CVD) among patients with Takayasu arteritis (TA), few studies have identified its clinical correlates. The aim of this study was to analyse the prevalence of CVD and its association with traditional CV risk factors and disease-related variables in patients with TA.

METHODS
A total of 262 consecutive patients with a diagnosis of TA between January 2009 and July 2013 were included in this study. The primary outcome was CVD, defined as the presence of a previous history of myocardial infarction, angina, coronary disease, coronary bypass surgery, coronary angioplasty, and stroke. Multivariate logistic regression analysis was used to determine the relationship of conventional CV risk factors and TA-related variables to the presence of CVD.

RESULTS
CVD was present in 64 (24.4%) of patients with TA. Of the total cohort, 16 (6.1%) had a history of myocardial infarction, 31 (11.8%) had angina and 24 (9.2%) had stroke. Multivariate logistic regression analysis revealed that anaemia (OR, 2.449; 95% CI: 1.167-5.141, p=0.018), low body mass index (OR, 0.821; 95% CI: 0.723-0.932, p=0.002), advancing age (OR, 1.050; 95% CI: 1.013-1.088, p=0.007), hyperlipidaemia (OR, 3.792; 95% CI: 1.647-8.727, p=0.002), and family history of CVD (OR, 2.915; 95% CI: 1.188-7.153, p=0.019) were significantly associated with the presence of CVD.

CONCLUSIONS
Our study suggests that in addition to traditional CV risk factors, anaemia and low body mass index are independently associated with increased CVD in patients with TA.
