Aim. The role of inflammation in atherothrombotic disorders is becoming increasingly recognized. The present study prospectively investigates relationships between inflammatory markers and hemostatic variables, and non-invasive measures of carotid artery atherosclerosis.
Methods. Markers of hemostasis (sP-selectin and fibrinogen), cytokines (IL-6, IL-8, TNF-a and MCP-1), inflammatory variables (hsCRP, SAA and calprotectin) and cell adhesion molecules (ICAM-1 and VCAM-1) as well as ultrasonography of the carotid arteries were assessed in 111 consecutive outpatients with manifest or suspected coronary artery disease (CAD).
Results. Thirty-eight patients with manifest cardiovascular disease had higher IL-6 (P<0.01) but not hsCRP levels. Higher levels of IL-6, calprotectin and VCAM-1 (all P<0.05) were found in 35 patients with carotid plaques. In the whole study population (n=109) an increased common carotid artery lumen diameter (LD) and cross sectional intima-media area (CIMA) was related to higher IL-6, IL-8 and MCP-1 levels (all P<0.05), and increased LD also to higher hsCRP, calprotectin (both P<0.05), sP-selectin and fibrinogen levels (both P<0.01). Both LD and CIMA were related to VCAM-1 (both P<0.01), but not to ICAM-1 levels. The intima-media thickness of the carotid artery was only positively related to MCP-1 levels (P<0.05). Only the relation between IL-6 and LD remained significant after adjustment for age, gender, body mass index, smoking status or present lipid-lowering treatment.
Conclusion. Several biomarkers of inflammation are related to ultrasonographic measures of carotid artery atherosclerosis in patients with moderate to high prevalence of CAD. IL-6 seems to be an independent and useful biomarker of atherosclerosis in this group of patients.
