Factors analysis and unstabe plaques of carotid atherosclerosis in ischemic cerebrovascular patients

Objective To explore the relative factors of unstable plaques of carotid atherosclerosis in ischemic eerebrovascular patients.Methods Carotid arteries of a total of 132 cases with ischemic cerebrovascular disease of carotid artery system were inspected by color Doppler ultrasound.The plaques discovered were classified according to ultrasonic appearance and their stability was judged.The relation between hypertension,diabetes,hyperlipemia, smoking and unstable plaques of carotid atheroselerosis was analyzed.Results The most common site of plaque for- mation was the bifurcate of the common carotid artery(56.99%),and the second commonest was carotid artery (23.12%).The incidence of unstable plaques in the patients with smoking,hypertension and diabetes was higher than those without them(P0.05).The level of HDL of the groups with unstable plaques was lower than the sta- ble plaques and the level of LDL was on the contrary(P0.05,P0.001).Conclusion There was a close rela- tionship between these risk factors including hypertension,diabetes,hyperlipemia,smoking,and unstable plaques of carotid atherosclerosis in ischemic cerebrovascular diseases.
