BACKGROUND
Internal carotid artery occlusion (ICAO) causes high annual rates of mortality and morbidity. It has been established that atherosclerosis is the normal cause of ICAO. As the pathogenesis of atherosclerosis may involve blood lipids, inflammatory factors and other biomarkers, the aim of this study was to assess the changes in these biomarkers and investigate the relationship between these biomarkers and the development of ICAO in stroke patients.
METHODS
A total of 89 ischaemic stroke inpatients with ICAO (ICAO group) and 89 without ICAO (control group) were studied, retrospectively. The serum was collected from each patient on the 3(rd) day of admission, to measure the lipid parameters and biomarkers, e.g. high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), and lactic acid (LA). Histories were taken including age, gender, smoking history, and disease history. Additional analysis was carried out to compare between the genders and evaluate the association between certain biomarkers and ICAO.
RESULTS
Among the 89 ICAO cases in this study, the serum levels of hs-CRP, ESR and LA were significantly higher than those in the control group (p ≤ 0.001). No significant differences were found in the mean levels of total cholesterol, triacylglycerol, HDL cholesterol or glucose, or the known risk factors. Gender also had no influence on these biomarkers. Logistic regression analysis indicated that hs-CRP, ESR and LA were significantly associated with ICAO (p ≤ 0.05).
CONCLUSIONS
These results suggest that hs-CRP, ESR and LA are associated with ICAO in ischaemic stroke patients, but gender has no effect. Therefore, Hs-CRP, ESR and LA may be useful in the early detection of patients with ICAO.
