摘要
Background and purposes: Procalcitonin has been suggested as a new risk factor in atherosclerotic disease. However, whether procalcitonin levels are associated with the risk of carotid atherosclerosis remains unclear. This study aimed to investigate the relationship between procalcitonin levels and carotid atherosclerosis among patients with first-ever acute ischemic stroke. @@@ Methods: Two hundred and thirty consecutive patients were prospectively enrolled in this study. Serum procalcitonin concentrations were measured at admission for all patients. We also performed ultrasound examination to detect the mean carotid intima-media thickness, presence of carotid-wall thickening, plaque and significant stenosis. Multiple regression analysis was used to estimate the association between procalcitonin levels and carotid atherosclerosis. @@@ Results: The median procalcitonin concentration was 0.051 mu g/L (interquartile range, 0.036-0.080 mu g/L). Of the 230 patients, 102 (44.3%) had carotid-wall thickening, 113 (49.1%) had plaque and 77 (33.5%) had significant stenosis. After adjusting for all potential confounders by multiple logistic regression analysis, patients with procalcitonin levels in the fourth quartile, compared with the first quartile, were more likely to have carotid-wall thickening [odds ratio 2.288, 95% confidence intervals 1.042-5.021, P = 0.039] and significant stenosis [odds ratio 3.871, 95% confidence intervals 1.690-8.867, P = 0.003]. Furthermore, the linear regression analysis revealed a significant positive correlation between procalcitonin levels and the mean carotid intima-media thickness (beta = 0.162, P = 0.012). @@@ Conclusions: Higher procalcitonin concentrations at admission might be associated with carotid-wall thickening and significant stenosis in ischemic stroke patients.
