Abstract:
Objective To investigate the correlation between HCY (Homocysteine),folate,vitamin B12 and head and neck vascular stenosis in patients with ischemic cerebrovascular disease.Methods 225 patients with ischemic cerebrovascular disease in Tangdu Hospital of the Fourth Military Medical University were enrolled in the study from April 2016 to October 2016.The serum levels of HCY,folate and vitamin B12 were detected.CT angiography (CTA) was uesd for patients with head and neck vascular scanning.According to whether the presence of vascular stenosis,patients were classified as no vessel stenosis group and vascular stenosis group.According to the degree of stenosis,patients were classified as no vascular stenosis group,mild moderate stenosis group and severe stenosis group.Results The HCY levels in the vascular stenosis group were significantly higher than no vessel stenosis group,while the levels of folate and vitamin B12 were significantly lower than no vessel stenosis group,the differences were statistically significant (t=9.656,7.140 and 8.350,all P＜0,01).The HCY levels in mild moderate stenosis group and severe stenosis group were significantly higher than no vessel stenosis group,and the HCY levels in severe stenosis group were significantly higher than mild moderate stenosis group,the differences were statistically significant (t=6.108,9.401 and 5.273,all P＜0.01).The folate levels in mild moderate stenosis group and severe stenosis group were significantly lower than no stenosis group,the differences were statistically significant (t=5.574 and 5.988,all P＜0.01).The vitamin B12 levels in mild moderate stenosis group and severe stenosis group were significantly lower than no stenosis group,the differences were statistically significant (t=4.548 and 7.816,all P＜0.01).The degree of head and neck vascular stenosis and serum levels of HCY were positively correlated (r=0.331,P＜0.01).The degree of head and neck vascular stenosis and levels of vitamin B12 were negatively correlated (r=-0.279,P＜0.05).Conclusion The levels of HCY,folate and vitamin tB12 were closely related to the degree of head and neck vascular stenosis.HCY,folate,vitamin B12 and head and neck CTA play important roles in patients with ischemic cerebrovascular disease clinically.
