ABSTRACT
BACKGROUND:
Aortic stiffness and intima-media thickness (IMT) are known to be associated with ischemic stroke. The aim of the present study was to investigate the differences of aortic stiffness and IMT between cerebral infarction (CI) and transient ischemic attack (TIA).METHODS:
A total of 500 patients with acute stroke were divided into 2 groups the TIA group (n = 230, 62.4 +/- 12 years, 144 males) versus CI group (n = 270, 63.4 +/- 11 years, 181 males). Aortic stiffness index and IMT, as well as conventional cardiovascular risk factors, were compared.RESULTS:
The prevalence of hypertension, diabetes, and dyslipidemia were significantly higher, and left atrial volume and E/E' were significantly elevated in the CI group than in the TIA group. Carotid IMT was significantly thicker in the CI group than in the TIA group. Aortic stiffness index beta was significantly higher (7.99 +/- 2.70 vs. 7.02 +/- 4.30, p = 0.043) and aortic IMT was significantly thicker (1.53 +/- 0.41 vs. 1.45 +/- 0.39 mm, p = 0.040) in the CI group than in the TIA group. Aortic stiffness index beta was significantly correlated with the IMT of the aorta (r = 0.279, p = 0.014), right (r = 412, p < 0.001) and left carotid artery (r = 441, p < 0.001).CONCLUSION:
Aortic stiffness index beta and IMT were significantly higher in patients with CI than TIA. The result of the present study suggested that CI is associated with more advanced degree of atherosclerotic and arteriosclerotic process than TIA.Palavras-chave
