一、吸烟是中风独立的危险因素1、吸烟可引起血粘度的升高,如红细胞压积升高、全血粘度包括高、低切变率及还原粘度均显著升高,红细胞变形能力降低和聚集性增强。长期吸烟可导致慢性一氧化碳中毒,由于一氧化碳对血红蛋白亲和力比氧高200倍以上,改变了氧的解离曲线,增加了血红蛋白的亲和力,故缺氧使红细胞的生成增多,致红细胞压积升高。2、香烟中含有大量尼古丁,吸烟时吸入体内的尼古丁使肾上腺释放肾

First, smoking is a risk factor for stroke independence 1, smoking can cause increased blood viscosity, such as increased hematocrit, whole blood viscosity, including high, low shear rate and reducing viscosity were significantly increased, reduced erythrocyte deformability and Aggregation enhancement. Long-term smoking can lead to chronic carbon monoxide poisoning. Since the affinity of carbon monoxide for hemoglobin is over 200 times higher than that of oxygen, the oxygen dissociation curve is changed and the affinity of hemoglobin is increased. Therefore, hypoxia increases the production of erythrocytes and causes hematocrit to increase. 2, cigarettes contain large amounts of nicotine, smoking inhalation of nicotine in the body so that the release of adrenal kidney
