Increased carotid intima–media thickness associated with high hs-CRP levels is a predictor of unstable coronary artery disease

Increased values of carotid intima-media thickness (CIMT) and high-sensitivity C-reactive protein (hs-CRP) are predictors of acute coronary events. We analysed the link between CIMT and hs-CRP in cases with coronary artery disease (CAD). From 1 January to 30 June 2012, we evaluated 43 patients with acute coronary syndrome (group A), 50 patients with stable coronary artery disease (group B) and 50 healthy volunteers (group C). All were analysed for CIMT and hs-CRP levels. CIMT values were higher in groups A and B (0.94 ± 0.21 mm, 0.89 ± 0.19 mm, respectively) and lower in group C (0.64 ± 0.09 mm), and this was statistically significant (p < 0.0001). However the values of hs-CRP were higher in group A (1.87 ± 0.36 mg/l) and lower in groups B and C (1.07 ± 0.28 mg/l, 0.97 ± 0.45 mg/l, respectively) and this was also statistically significant (p < 0.0001).
