Abstract

Cushing’s syndrome (CS) is associated with high cardiovascular risk. The aim of this study was to analyze intimal media thickness (IMT) in patients with CS and compare them with subjects matched for similar conventional and independent cardiovascular risk factors. Twenty eight patients with CS (mean age: 40.7 ± 2.5 y) and 28 subjects (mean age: 41.1 ± 14 y) matched for sex, age, smoking habit, body mass index, blood pressure levels, glucose and lipid metabolism were evaluated. IMT was measured at right and left common carotid (CC), carotid bulb (BC), aorta (Ao) and femoral (F) levels by B-echo-Doppler ultrasonography. Although parameters of cardiovascular risk factors did not differ statistically between patients and controls, IMT was significantly increased (right and left CC-IMT, p < 0.05; right and left BC-IMT, p < 0.01, Ao-IMT p < 0.05) and wall plaques were more common (14.2 % vs. 7.1 %) in patients. In CS patients, CC-IMT and F-IMT correlated positively and significantly with fasting glucose (right CC-IMT: r2 = 0.37, p = 0.05; left CC-IMT: r2 = 0.43, p = 0.02; right F-IMT: r2 = 0.57; p < 0.01; left F-IMT: r2 = 0.47, p = 0.01) and HOMA index (left CC-IMT: r2 = 0.64, p < 0.01 and left F-IMT: r2 = 0.48, p < 0.05). The CS patients’ waist-to-hip ratio (WHR) was evaluated and correlated positively and significantly with CC-IMT (right: r2 = 0.53, p = 0.01 and left: r2 = 0.44, p = 0.05). No correlation was found between IMT and cortisol levels, however. In conclusion, patients with CS have more severe atherosclerotic damage than a population matched for similar cardiovascular risk factors. Multiple events related to long-term cortisol effects on metabolism and at vascular and endothelial sites may increase the risk of cardiovascular damage in patients with CS.
