TITLE: Impact of dual antiplatelet therapy at different durations on the prognosis and safety of patients after percutaneous coronary intervention:a meta-analysis
摘要: 目的 评价双联抗血小板治疗(DAPT)不同持续时间对经皮冠状动脉介入(PCI)术后患者预后及安全性的影响。方法检索PubMed、TheCochraneLibrary、Embase、Medline、中国知网、万方数据、维普网,收集DAPT用于PCI术后患者的随机对照试验,检索时间为建库至2026年3月20日。经文献筛选、资料提取及质量评价后,采用RevMan5.4软件进行Meta分析。结果共纳入19项研究,共计44072例患者。Meta分析结果显示,两组患者的主要不良心血管事件发生率[相对危险度(RR)=0.99,95%置信区间(CI)(0.90,1.08),P=0.80]、全因死亡率[RR=0.93,95%CI(0.81,1.05),P=0.24]、心血管相关死亡率[RR=0.87,95%CI(0.73,1.04),P=0.12]、心肌梗死发生率[RR=1.11,95%CI(0.97,1.27),P=0.14]、支架内血栓发生率[RR=1.50,95%CI(0.99,2.28),P=0.06]、血运重建发生率[RR=1.00,95%CI(0.86,1.15),P=0.95]及卒中发生率[RR=1.03,95%CI(0.82,1.28),P=0.81]比较,差异均无统计学意义。DAPT短期组患者的出血事件发生率显著低于DAPT长期组[RR=0.61,95%CI(0.53,0.69),P<0.00001]。结论PCI术后患者短期与长期使用DAPT的全因死亡、心血管相关死亡、心肌梗死、支架内血栓、血运重建、卒中及主要不良心血管事件发生风险相当,但短期使用DAPT在降低出血风险方面优势较突出。
ABSTRACT: OBJECTIVE To evaluate the impact of dual antiplatelet therapy (DAPT) at different durations on prognosis and safety after percutaneous coronary intervention (PCI).METHODS PubMed,The Cochrane Library, Embase, Medline, CNKI, Wanfang data, and VIP database were searched to collect randomized controlled trials of DAPT in patients after PCI, from database inception to March 20, 2026. After literature screening, data extraction, and quality assessment, a meta-analysis was performed using RevMan 5.4 software.RESULTS A total of 19 studies were included, involving 44 072 patients. Meta-analysis results showed that there were no statistically significant differences between the two groups in incidence rate of major adverse cardiovascular events [relative risk(RR)=0.99, 95% confidence interval(CI)(0.90, 1.08), P =0.80], all-cause mortality rate[RR=0.93, 95%CI(0.81,1.05), P =0.24], cardiovascular-related mortality rate[RR=0.87, 95%CI(0.73, 1.04), P =0.12], the incidence rate of myocardial infarction [RR=1.11,95%CI(0.97,1.27), P =0.14], the incidence rate of stent thrombosis[RR=1.50,95%CI(0.99,2.28), P =0.06], the incidence rate of revascularization[RR=1.00, 95%CI(0.86, 1.15), P =0.95], the incidence rate of stroke[RR=1.03, 95%CI(0.82, 1.28), P =0.81]. The incidence rate of bleeding events in the short-term DAPT group was significantly lower than in the long-term DAPT group[RR=0.61, 95%CI(0.53, 0.69), P <0.000 01].CONCLUSIONS Short-term and long-term DAPT in patients after PCI were associated with comparable risks of all-cause mortality, cardiovascular-related mortality, myocardial infarction, stent thrombosis, revascularization, stroke, and major adverse cardiovascular events; however, short-term DAPT showed a more prominent advantage in reducing bleeding risk.
