摘要目的:分析马来酸桂哌齐特注射液对急性缺血性卒中（acute ischemic stroke，AIS）伴高血压患者血压的影响。方法:本研究是马来酸桂哌齐特注射液（桂哌齐特）治疗急性缺血性卒中随机、双盲、多中心、安慰剂平行对照的临床确证研究的一个亚组分析，该研究在中国开展，从2016年8月开始至2019年2月结束，连续入组发病时间≤48 h，美国国立卫生研究院卒中量表（NIHSS）评分为7~25分的急性前循环非心源性脑梗死患者。主要终点指标为患者接受治疗期内（14 d）的血压均值及血压正常人群比例的变化。进一步，还探讨了既往合并高血压病史对结果的影响。结果:本分析纳入该大型临床研究中伴高血压的809例患者。患者接受治疗过程中，AIS患者血压均值、治疗结束后血压正常人群比例（60.5% 比 59.0%， P>0.05）在桂哌齐特组和安慰剂对照组间差异无统计学意义。 结论:急性缺血性卒中患者应用马来酸桂哌齐特注射液治疗，不影响患者的临床血压管理。

abstractsObjective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.
