Abstract
Objective: Inflammation seems to be crucial in the pathogenesis of abdominal aortic aneurysm (AAA). Previous research links inflammatory biomarkers, such as high sensitivity C-reactive protein (HS-CRP), to AAA. Few studies, however, have used a prospective design. The aim of this study was to examine whether individuals with elevated HS-CRP have increased risk of AAA, using a prospective and population based design.
Methods: This prospective, population based, cohort study included 46 322 participants in the Trøndelag Health Study (HUNT) in Norway (53.7% women). During a median follow up time of 12.6 years (range 0 - 26 years), 407 individuals were diagnosed with AAA (28.8% women). Cox proportional hazard regression was applied to examine associations between HS-CRP and risk of AAA. HS-CRP was treated either as a continuous or a categorical variable (dichotomised at 2 mg/L, 1 mg/L, median (1.2 mg/L), or as quartiles).
Results: The hazard ratio (HR) of developing AAA per 1 mg/L increase in HS-CRP (continuous HS-CRP) was 1.02 (95% CI 1.01 - 1.03) in the analysis adjusted for smoking, coronary heart disease, hypertension, diabetes, body mass index, and total cholesterol. Individuals with HS-CRP 2 mg/L or above had almost twice the risk of AAA compared with individuals with HS-CRP less than 2 mg/L (adjusted HR 1.84; 95% CI 1.51 - 2.25). Dichotomising HS-CRP at a clinical cut off point of 1 mg/L (adjusted HR 2.13, 95% CI 1.64 -2.76), or at the median of 1.2 mg/L (adjusted HR 2.12, 95% CI 1.62 - 2.76), slightly strengthened the HR. The adjusted HR gradually increased through the ordered HS-CRP quartiles, and was almost four times higher (HR 3.87, 95% CI 2.54 - 5.92) in the highest HS-CRP quartile (HS-CRP > 2.7 mg/L) compared with the lowest quartile (HS-CRP ≤ 0.6 mg/L).
Conclusion: Individuals with elevated HS-CRP had significantly increased risk of developing AAA.
期刊介绍：
The European Journal of Vascular and Endovascular Surgery is aimed primarily at vascular surgeons dealing with patients with arterial, venous and lymphatic diseases. Contributions are included on the diagnosis, investigation and management of these vascular disorders. Papers that consider the technical aspects of vascular surgery are encouraged, and the journal includes invited state-of-the-art articles.
Reflecting the increasing importance of endovascular techniques in the management of vascular diseases and the value of closer collaboration between the vascular surgeon and the vascular radiologist, the journal has now extended its scope to encompass the growing number of contributions from this exciting field. Articles describing endovascular method and their critical evaluation are included, as well as reports on the emerging technology associated with this field.
