Objective To explore the risk factors in 2 diabetes mellitus with cerebral infarction Methods:Patients with(n=58)and without diabetes mellitus(n=58)were comparatively studied on blood pressure, fasting blood glucose ,postprandial blood glucose,total cholesterol,glycosylated hemoglobin, unne mieroalbumin and plasma fibrinogen.Results:The data on blood pressure,lipids,blood glucose,glycosylated hemoglobin , unne mieroalbumin and plasma fibrinogen were significantly different between type 2 diabetics with and without complicating cerebral infarction.Conclusion:Early vigorous control of blood pressure,Intervention of risk factors including blood glucose,dyslipidemia and microalbuminuria should be the key to reduce complicating cerebral infarction in patients with 2 type diabetes mellitus
