Abstract:
Objective To investigate the relationship between levels of mean platelet volume (MPV) and carotid atherosclerosis in patients with acute cerebral infarction.Methods A total of 99 patients were chosen for the observation group.Another 30 healthy people were for control group.The level of mean platelet volume in all subjects was detected bby enzymatic cycling assay and the carotid intimamedia thickness(IMT) of all patients was checked using color Doppler echocardiography.According to IMT degree,the patients in observation group were divided into IMT nomal group,IMT mild stenosis group and IMT moderate,severe stenosis group.According to the size of area of skull CT or MRI brain infarction,groups can be divided into a small area of cerebral infarction group,middle area of cerebral infarction group,the large area cerebral infarction group.The level of mean platelet volume between observation group and control group as well each subgroup of observation group was compared,and its correlation with IMT was also analyzed.Results The level of mean platelet volume in observation group was higher than in healthy control group (P ＜ 0.05).Cerebral infarction patients with different degree of carotid stenosis group of peripheral blood MPV comparative difference was statistically significant(P =0.000).Pearson correlation analysis displayed that the level of mean platelet volume was positively correlated with IMT(r =0.331,P =0.000),and positively correlated with Cerebral infarction volume.The optimal cut-off value of MPV was 11.45,with a sensitivity of 41.4％ and a specificity of 86.7％ for predicting ischemic stroke.Conclusion Increased MPV is closely associated with carotid artery stenosis and its degree in cerebral infarction patients.
