Abstract:
Objective To investigate the relationship between Helicobacter pylori (Hp) infection and carotid atherosclerosis (CAS) progression in patients with high risk of stroke,and to provide clinical evidence for the primary prevention of stroke.Methods Three hundred and thirty-two patients with high risk of stroke were screened from 2 800 people who were consecutively selected and had health examination from June to December 2014 in the Department of Medical Center,General Hospital of Wanbei Coal and Electricity Group.Their clinical information was collected.A total of 267 patients whose carotid ultrasound examinations showed plaques and stenosis were selected for the study.Two hundred and three of the 267 patients who met the screening conditions and completed the follow-up were selected as study subjects.The Hp infection status was detected by the 14C urea breath test and the dynamic progression of CAS was observed.The risk factors of CAS progression were also analyzed.Results Hp infection was found in 170 of 332 patients with high risk of stroke.Among the 267 patients who prompted plaques and stenosis in carotid ultrasound in 2014,203 patients were followed up for 1 year,and 133 patients (65.5％,133/203) were found infected by Hp.Forty-six patients had suggestive carotid stenosis and stenosis aggravating in 2015,31 (67.4％,31/46) of which were found infected by Hp.Logistic regression analysis showed that smoking (OR =1.632,95％ CI 1.275-1.940,P =0.011),systolic blood pressure (OR =1.343,95％ CI 1.105-1.632,P =0.019),low density lipoprotein (OR =1.590,95％ CI 1.188-2.005,P =0.005),oxidative low density lipoprotein (OR =1.732,95％ CI 1.325-2.170,P =0.000) and Hp infection (OR =1.672,95％ CI 1.180-2.154,P =0.016) were independent risk factors for carotid atheroslerosis progression.Conclusions Hp infection was found closely related to CAS progression in patients at high risk of stroke.Positive and effective prevention of Hp infection,advocating smoking cessation and controlling blood pressure and blood fat can effectively reduce the incidence of stroke.
