Carotid ultrasound screening of ischemic cerebral apoplexy in high-risk group and exploration of behavioral influence factors

Abstract

Objective To investigate carotid atherosclerosis and its relevant risk factors of ischemic cerebral apoplexy in high-risk population and to explore new modes of behavioral influencing factors based on health management platform. Methods Using the carotid ultrasound screening of personnel undergoing physical examination, the differences of the related risk factors were studied among 1 152 cases of carotid atherosclerosis with different gender and different age and different disease periods. Results High-risk population between 40-49 years was mainly focused on mild lesions, and the numbers of serious lesions increased significantly among people older than 70; male patients numbered 51 were significantly much more than the females numbered 21 (P 0.05). Setting mild and serious period respectively as the dependent variables, and hypertension, overweight, dyslipidemia, diabetes mellitus, smoking, physical activity and atrial fibrillation as the independent variables to conduct logistic regression analysis, it showed that mild lesions were related to overweight, hypertension and dyslipidemia. The risk factors of serious lesion period included hypertension, overweight, diabetes mellitus, dyslipidemia, atrial fibrillation, smoking and lack of physical activity. The female detection rates of hypertension and dyslipidemia in female patients, which were 83.8% and 44.1% respectively, were higher than those in male patients, which were 67.6% and 31.0% respectively.The detection rates of smoking and arterial fibrillation in female patients, which were 0.7% and 0.3% respectively, were lower than those in male patients, which were 20.7% and 1.0% respectively. Conclusions Early detection of carotid atherosclerosis lesions and its relevant risk factors as soon as possible, and early intervention influencing factors to mild lesions to prevent the atherosclerosis from getting worse.A new model of zero level prevention can be developed to control of ischemic stroke based on health management platform.
