流行病学调查证实高血糖是中风的危险因素,Kannel发现男性糖尿病合并脑血栓形成的发病率比无糖尿病者高2.5倍,女性高3.6倍。但是中风之前高血糖对发展成中风的危险性不很确知,因为中风本身可以继发高血糖,特别轻度高血糖或糖耐量障碍不一定能说明中风之前的情况,这对评价糖尿病是中风危险因素是困难的。Gonen用测量糖化血红蛋白(GHB)可以指明病人在此之前1——3个月内的 Epidemiological investigation confirmed that hyperglycemia is a risk factor for stroke, Kannel found that male diabetes combined with cerebral thrombosis incidence of 2.5 times higher than those without diabetes, women 3.6 times higher. However, the risk of hyperglycemia developing into a stroke before stroke is not known because the stroke itself may secondary to hyperglycemia, especially mild hyperglycemia or impaired glucose tolerance does not necessarily explain the pre-stroke situation, which is a stroke for the assessment of diabetes Risk factors are difficult. Gonen used to measure glycated hemoglobin (GHB) can indicate the patient within the 1-3 months before
