[Show abstract][Hide abstract]ABSTRACT: MIAMI is a prospective multicenter clinical study designed to investigate the relationship between changes in carotid intima-media thickness (C-IMT) and changes in circulating markers of inflammation, thrombosis and endothelial activation in stable coronary patients treated for 20+/-3.7 months with 20mg/day atorvastatin.
Eighty-five subjects had their C-IMT, blood lipids and soluble markers measured at baseline, at the 12th month and at the end of the study. Almost all soluble markers decreased upon treatment except for high-sensitivity C-reactive protein (hs-CRP), interleukin-18 (IL-18), tissue factor pathway inhibitor-free (TFPI-free) and soluble vascular cell adhesion molecules-1 (sVCAM-1) which did not change significantly, and interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and soluble CD40 ligand (sCD40L) which increased. sCD40L, fibrinogen, tissue factor pathway inhibitor-total (TFPI-total), soluble intercellular adhesion molecules-1 (sICAM-1), sE-selectin, interleukin-8 (IL-8) and von Willebrand factor (vWF) changed significantly even after application of the Bonferroni correction for multiple comparisons. Changes in lipids did not correlate with C-IMT regression either when considered singly or when combined in a lipid score. Changes in soluble markers correlated poorly with C-IMT regression when analyzed singly, but strongly when combined in relevant composite scores (inflammation/coagulation score, endothelial activation score, soluble markers score and total score).
In patients with stable coronary artery disease treated with moderate doses of atorvastatin, carotid IMT regression correlated with changes of inflammation, thrombosis and endothelial activation profiles.

[Show abstract][Hide abstract]ABSTRACT: MIAMI was a prospective multicenter clinical study designed to investigate the relationship between changes in carotid intima-media thickness (C-IMT) and those in the levels of circulating markers of inflammation, thrombosis and endothelial dysfunction. The study was performed in a group of stable coronary patients treated for two years with a moderate dosage of atorvastatin (20mg/day). In this paper the cross-sectional relationship between C-IMT and the same circulating markers of inflammation, thrombosis and endothelial dysfunction measured at baseline was investigated.
Eighty-five subjects that had not used statins for at least two months were enrolled in the study. At time of enrollment, the levels of vascular cell adhesion molecule-1 (VCAM-1), intracellular adhesion molecule-1 (ICAM-1), E-selectin, interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-alpha, high-sensitivity C-reactive protein (hs-CRP), tissue factor (TF), tissue factor pathway inhibitor (TFPI), von Willebrand factor (vWF), fibrinogen, total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL), and triglycerides were measured, in parallel with C-IMT assessment.
In cross-sectional analyses, markers of endothelial perturbation (i.e. E-selectin) and TFPI were more strongly correlated with arherosclerotic burden than markers of inflammation. The baseline picture in this study indicates that E-selectin and TFPI are linked with atherosclerotic burden.
