title: [Carotid intimal-medial thickening and endothelial function in coronary artery disease].
abstract: OBJECTIVE
  To investigate the correlation between the endothelial function and the carotid intimal-medial thickening (IMT) in a population of patients with coronary artery disease, as well as that between the endothelial function and carotid IMT with the severity of the coronary lesions.
  
  
  METHODS
  Forty-three patients aged 60.5+/-9.2 years, (67.4% males) with coronary artery disease at the coronariography were studied. Endothelial function was assessed using the brachial artery reactivity test (BART), which measured the percentage of flow-mediated dilatation (%FMD). The carotid IMT was evaluated through vascular ultrasound.
  
  
  RESULTS
  The mean %FDM was 4.7 +/- 3.6 and the mean carotid IMT was 1.08 +/- 0.23 mm. The carotid MIT and %FMD measurements showed a statistically significant correlation, with Spearmans coefficient of 0.315, p= 0.042, demonstrating that lower %FMD values corresponded to an increased carotid IMT (r = -0.315, p = 0.042). There was no correlation between %FMD or IMT and the severity of coronary lesions.
  
  
  CONCLUSIONS
  The presence of a correlation between carotid IMT and %FMD demonstrates a concomitance of anatomical and functional vascular alterations in coronary artery disease, regardless of the severity of the atherosclerotic lesions.
