The aim of this study was to show the effects of Khat on acute cerebral infarction (ACI), specifically regarding blood pressure, age and gender, and to open the door for further neurological research.
We collected 358 patients with ACI, and 335 volunteers from Al-Thowra Modern General Hospital in Sanaa, Yemen, and Thamar General Hospital, Thamar City, approximately 100 km south of Sanaa. During a one year period, from February 2003 to March 2004, we conducted research regarding blood pressure, age, and gender related to the chewing or not chewing of Khat. We conducted a comparison between the ACI group and the volunteer group, using the SPSS 10.0 Chi-square statistical methods.
Results show that Khat increases blood pressure in patients with ACI. The gender-related effects show that Khat affects a greater percentage of males (74.6%) compared to females (25.4%), Khat chewers in the patient group showed a statistical significance of p<0.001. The 358 ACI patients had a mean age of 51.5 years old, while in the 335 normal individuals the mean age was 42.5 years old, showing a statistical significance of p<0.001.
Khat is a risk to blood pressure in ACI patients, with a statistical significance of p<0.001. Khat effects males more than females, and Khat chewers are more affected than non-chewers with a statistical significance of p<0.01. Khat also shows a significant relationship with age, affecting older persons (p<0.001).
本研究旨在揭示巧茶对急性脑梗死（ACI）的影响，特别是在血压、年龄和性别方面，并为进一步的神经学研究打开大门。
我们从也门萨那的阿尔索拉现代综合医院和位于萨那以南约100公里的塔玛尔市的塔玛尔综合医院收集了358例ACI患者和335名志愿者。在2003年2月至2004年3月的一年时间里，我们针对与是否咀嚼巧茶相关的血压、年龄和性别进行了研究。我们使用SPSS 10.0卡方统计方法对ACI组和志愿者组进行了比较。
结果显示，巧茶会使ACI患者的血压升高。与性别相关的影响表明，与女性（25.4%）相比，巧茶对男性的影响比例更高（74.6%），患者组中咀嚼巧茶者的p值具有统计学意义（p<0.001）。358例ACI患者的平均年龄为51.5岁，而335名正常个体的平均年龄为42.5岁，p值具有统计学意义（p<0.001）。
巧茶对ACI患者的血压构成风险，p值具有统计学意义（p<0.001）。巧茶对男性的影响大于女性，咀嚼巧茶者比不咀嚼者受影响更大，p值具有统计学意义（p<0.01）。巧茶还与年龄存在显著关系，对老年人影响更大（p<0.001）。
