摘要:目的 急性冠状动脉综合征(acute coronary syndrome,ACS)的亚洲患者通常易受标准剂量替格瑞洛的影响,从而增加出血事件的风险。因此,回顾性分析半量替格瑞洛是否可提供更优的安全性及相似疗效显得至关重要。方法 收集2017年1月至2019年11月在宁波大学附属第一医院成功接受经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后的ACS患者的临床资料,根据替格瑞洛的使用剂量,分为标准剂量替格瑞洛组(90mg,56例)及半剂量替格瑞洛组(45mg,52例)。比较两种用药方案的临床结果,对不同随访期的临床事件进行了标志性分析,其中安全性终点定义为患者PCI术后与出血相关的并发症。疗效终点是主要心脑血管严重不良事件(major adverse cardiovascular and cerebrovascular events,MACCE)。结果 在整个随访期内,根据出血学术研究会(bleeding academic research consortium,BARC)标准,半剂量替格瑞洛组的1、2或3型的出血累积发生率低于标准剂量组(P<0.05),尤其是1年以上(P<0.05)。同时不同剂量替格瑞洛在MACCE发生率无显著差异(P>0.05)。结论 半量替格瑞洛可减少1、2或3型出血风险的发生,并且在MACCE中其疗效不劣于标准剂量治疗。这为ACS南方人群患者PCI术后长期出血和缺血之间使用半剂量替格瑞洛提供更好的依据。

Therefore, it is crucial to retrospectively analyze whether half dose ticagrelor can provide better safety and similar therapeutic effects. Methods Collect clinical data of ACS patients who successfully underwent percutaneous coronary intervention (PCI) at the First Affiliated Hospital of Ningbo University from January 2017 to November 2019. According to the dosage of ticagrelor used, they were divided into a standard dose ticagrelor group (90mg, 56 cases) and a half dose ticagrelor group (45mg, 52 cases). Comparing the clinical outcomes of two medication regimens, a landmark analysis was conducted on clinical events during different follow-up periods, with the safety endpoint defined as bleeding related complications after PCI in patients. The efficacy endpoint is major adverse cardiovascular and cerebrovascular events (MACCE). Results During the entire follow-up period, according to the bleeding academic research consortium (BARC) standards, the cumulative incidence of type 1, 2, or 3 bleeding in the half dose ticagrelor group was lower than that in the standard dose group (P<0.05), especially after more than 1 year (P<0.05). There was no significant difference in the incidence of MACCE between different doses of ticagrelor (P>0.05). Conclusion Half dose ticagrelor can reduce the risk of type 1, 2, or 3 bleeding and its efficacy in MACCE is not inferior to standard dose treatment. Therefore, providing better evidence for the use of half dose ticagrelor between long-term bleeding and ischemia after PCI in ACS patients in the southern population.
