以脑梗塞面积大小来分为大梗塞、小梗塞和腔隙性梗塞三个亚型，对１６５例急性脑梗塞患者从临床多方面进行对比分析。结果显示：高血压是最主要的危险因素，以老年组及高龄组为多（Ｐ＜０．０１），性别间无差异；高血压合并高血糖或高血脂者较多，统计学有显著差异（Ｐ＜０．０５）；高血压及高血脂对肌力恢复及病死率无影响（Ｐ＞０．０５），高血糖则有影响（Ｐ＜０．０５）；脑梗塞分型与有无高血压的关系不大，组间比较无统计学意义（Ｐ＞０．０５），但组间的肌力恢复及病死率比较则有显著性差异（Ｐ＜０．０５），以大面积梗塞组肌力恢复无进步或死亡最多，梗塞灶的大小与高血糖有关（Ｐ＜０．０１），与高血脂则无关（Ｐ＞０．０５）。由于梗塞灶大小的分型对肌力恢复及病死率判断有统计学意义，故这种分型有助于对患者的病情判断及预后估计，亦有利于药物治疗的选择。
The size of cerebral infarction is divided into three subtypes of large infarction, small infarction and lacunar infarction. 165 cases of acute cerebral infarction patients from many aspects of clinical comparative analysis. The results showed that hypertension was the most important risk factor, which was mostly in the elderly group and the elderly group (P <0.01), with no significant difference among the sexes. There were more cases of hypertension with hyperglycemia or hyperlipidemia, with significant difference (P <0.05). Hypertension and hyperlipidemia had no effect on muscle strength recovery and mortality (P> 0.05), and hyperglycemia had an effect (P <0.05) (P> 0.05), but there was a significant difference between the two groups in the recovery of muscle strength and the mortality (P <0.05). In large-scale infarction No significant improvement in muscle strength or death, the size of infarction was related to hyperglycemia (P <0.01), but not to hyperlipidemia (P> 0.05). Because infarct size classification of muscle strength recovery and mortality rate was statistically significant, so this classification helps to determine the patient’s condition and prognosis, but also conducive to the choice of drug treatment.
