目的观察高血压及红细胞压积对高原地区世居者(藏族)和移居者(汉族)脑梗死发病的影响。方法回顾性分析比较高原地区146例藏汉民族脑梗死患者的年龄、性别、血压和红细胞参数,了解它们对不同民族患者脑梗死发生的影响。结果藏族患者发病平均年龄明显大于汉族患者,汉族男性患者比例显著高于藏族(P<0.05)。2组高血压差异无统计学意义(P>0.05)。汉族患者的平均血红蛋白量和红细胞压积显著高于藏族患者(P<0.05)。结论红细胞增多对高原汉族人群脑梗死的发生有重要意义。
Objective To observe the effects of hypertension and hematocrit on the incidence of cerebral infarction in the settlers (Tibetan) and migrants (Han nationality) in the plateau area. Methods We retrospectively analyzed the age, gender, blood pressure and erythrocyte parameters of 146 Tibetan and Han nationality patients with cerebral infarction in high altitude area and compared their influence on the occurrence of cerebral infarction in different nationalities. Results The average age of onset was significantly higher in Tibetan patients than in Han patients. The proportion of Han male patients was significantly higher than that of Tibetan (P <0.05). No significant difference between the two groups of hypertension (P> 0.05). The mean hemoglobin and hematocrit of Han patients were significantly higher than those of Tibetan patients (P <0.05). Conclusion The increase of erythrocytes is of great significance to the occurrence of cerebral infarction in plateau Han population.
