Abstract:
Objective To investigate the correlation between the stroke-related risk factors and carotid stenosis lesions of ≥40 year′s old Han and minority populations in a community in Beijing as well as the clinical value of carotid ultrasound screening. Methods An investigation of risk factors for stroke and the results of carotid artery ultrasound screening in 510 cases (≥40 years old) Han population and 243 minority population in a community in Minzu University of China in Beijing in April 2014 were analyzed. Results (1)The prevalence of hypertension of the Han population was significantly higher than that of the minority population (53. 5% [n=273] vs. 44. 4% [n=108]; χ2 =5. 43,P=0. 02). (2) The detected rate of carotid intima-media thickness ( IMT ) of the Han population was higher than that of the minority population (77. 5% [n=395] vs. 69. 1% [n=168]; χ2 =6. 03,P=0. 01). There was no significantly difference in the detected rates of carotid plaques and carotid artery stenosis between the two groups (χ2 =0. 56,1. 13 respectively,all P>0. 05). (3) Hypertension and smoking were the independent risk factors for carotid-intima thickening in Han population ( hypertension:OR,1. 851;95% CI 1. 213-2. 825; smoking:OR,2. 311;95% CI 1. 065-5. 016;all P<0. 05). Hyperlipidemia was an independent risk factor for carotid artery intima-media thickening in the minority population (OR,2. 586;95% CI 0. 952-8. 694,P<0. 01). Conclusion To investigate the risk factors for stroke in minority population in China are of particular importance for the prevention of carotid atherosclerotic disease. Carotid ultrasound examination is an important diagnostic technique for early detection of carotid atherosclerotic disease.
