ABSTRACT
Objective:
To explore the differences of one year death and stroke recurrence between ischemic stroke patients with intracranial atherosclerotic stenosis or occlusion of anterior circulation and those of posterior circulation.Methods:
All the patients were from the Chinese Intracranial Atherosclerosis Study (CICAS), between October 2007 and June 2009; patients with extracranial stenosis or occlusion, patients without acute infarction by diffusion weighted image, and patients with intracranial atherosclerosis of both anterior and posterior circulation were excluded.All the enrolled patients were divided into three groups no significant intracranial atherosclerosis group (n=964), anterior circulation intracranial atherosclerosis group (n=440), posterior circulation intracranial atherosclerosis group (n=233). One year outcome was evaluated by any cause of death and stroke recurrence.Results:
Of the 1 637 patients, 30 cases were died and 58 cases had stroke recurrence within one year.Compared with no significant intracranial atherosclerosis group, adjusted hazard ratio (95% confidence interval) of one-year death for anterior and posterior circulation intracranial atherosclerosis group were 1.349 (0.311-5.851), 4.542 (1.227-16.813), respectively.Adjusted hazard ratio (95% confidence interval) of one year stroke recurrence were 1.663 (0.620-4.460) and 2.464 (0.935-6.493), respectively.Conclusions:
Ischemic stroke patients with intracranial atherosclerosis of posterior circulation has higher risk of one year death. One year stroke recurrence risk for patients with intracranial atherosclerosis of anterior and posterior circulation needs to be further evaluated.Palavras-chave
