ABSTRACT
Objective Carotid atherosclerotic plaque is regarded as an important risk factor for ischemic cerebrovascular disease.This study analyzed the factors influencing the number of carotid atherosclerotic plaques in patients with ischemic stroke.Methods We selected 194 patients with crerbral infarction admitted to the Department of Neurology of Second Hospital Affiliated to Lanzhou University from December 2015 to December 2016.Neck vascular color Doppler ultrasound test was performed,and the number of carotid atherosclerotic plaques in each patient was counted.According to the number,we divided them into three groups:single,double and multiple.The patients'sex,age,hypertension,hyperlipemia,diabetes and history of ischemic stroke were recorded. Multivariate Logistic regression analysis was used to analyze the factors influencing plaques.Results Multivariate Logistic regression analysis showed that gender,hypertension,hyperlipidemia,and history of cerebral infarction were risk factors for single carotid artery plaque;hyperlipidemia and diabetes mellitus were risk factors for double carotid artery plaque;and gender,diabetes,and history of cerebral infarction were risk factors for multiple carotid artery plaque.Conclusion Different numbers of plaques may have common risk factors but different numbers of plaque morphology have their own risk factors.
