Abstract

OBJECTIVES:

to investigate the level of inflammatory markers between symptomatic and asymptomatic carotid stenosis patients.

DESIGN:

cross-sectional study.

MATERIALS AND METHODS:

a prospective study of 137 consecutive patients, admitted electively for carotid endarterectomy during 1997-2000, was conducted. 125 patients had cerebrovascular symptoms: either stroke (neurological deficit >24 h), Transient ischaemic attack (neurological deficit<24 h) or amaurosis fugax. Twelve patients were asymptomatic. A medical history and a fasting venous blood sample were taken from each patient around 6 weeks before surgery. The plasma concentrations of cholesterol and of inflammatory markers; (high sensitivity C-reactive protein (hs-CRP), sICAM-1, sVCAM-1, sE-selectin) were determined.

RESULTS:

the concentration of hs-CRP in the symptomatic group (3.9 mg/L) was significantly higher than in the asymptomatic group (2.1 mg/L; p = 0.04). These concentrations were within normal range (<10 mg/L). sICAM-1, sVCAM-1, sE-selectin and total cholesterol concentrations were not different between the two groups.

CONCLUSION:

plasma hs-CRP was elevated in symptomatic compared to asymptomatic patients with carotid artery disease. High sensitivity C-reactive protein has been shown to be of prognostic value in a number of cardiovascular conditions and this study suggests it may be of value to identify patient at high risk of developing neurological deficits.
