Is C-reactive protein a better predictor of recurrent carotid disease following carotid endarterectomy than established risk factors for atherosclerosis?

OBJECTIVES: To identify possible relation between established and novel risk factors for atherosclerosis (gender, age, diabetes mellitus, hypertension, smoking and C-reactive protein) and possibility of carotid restenosis following carotid endarterectomy (CEA). MATERIALS AND METHODS: A prospective study of 193 consecutive patients, admitted electively for carotid endarterectomy during 68 months, was conducted. 131 patients had symptomatic and 62 asymptomatic carotid disease. An attempt was made to follow-up on all operated arteries with duplex sonography at 2 month, 6 months, 12 months, and 24 months postoperatively. The correlation of previously mentioned variables (gender, age, diabetes mellitus, hypertension, smoking and average values of C-reactive protein) with progressive or recurrent disease was determined by chi-square analysis and analysis of variance. RESULTS: Of all 193 examined patients 29 demonstrated increasing degree of artery stenosis, while recurrent artery stenosis of >69% was diagnosed in 11 patients. Age, gender, hypertension, and diabetes did not play a significant role in the presence of progressive (or recurrent) disease, while active smokers and patients with preoperative and average C-reactive protein (CRP) levels over 3.0 mg/L had a greater propensity to develop progression (or recurrence) of carotid disease. CONCLUSION: Increased levels of CRP in serum may be a better predictor of carotid restenosis after CEA than are cholesterol levels and other established risk factors for vascular disease – except active smoking
