摘要
目的:比较卵圆孔未闭(patent foramen ovale,PFO)封堵术与药物治疗对隐源性卒中患者的临床疗效及安全性。方法:系统检索PubMed、Embase、Cochrane图书馆、中国知网、万方及维普数据库,筛选研究PFO封堵术治疗隐源性卒中患者临床疗效及安全性的随机对照试验(randomized controlled trial,RCT),采用Stata12.0软件进行meta分析。结果:总共纳入5项RCT研究,共计3 440例患者。结果显示,与药物治疗组相比,PFO封堵组脑卒中复发率显著降低(RR=0.43,95%CI:0.20~0.91,P=0.027,I2=58.8%),但一过性脑缺血发作风险并没有降低(RR=0.78,95%CI:0.53~1.15,P=0.212,I2=0.0%)。安全性方面,与药物相比,PFO封堵术不降低全因死亡(RR=0.81,95%CI:0.39~1.66,P=0.559,I2=0.0%)、大出血(RR=0.97,95%CI:0.42~2.26,P=0.949,I2=34.6%)风险,但增加新发心房颤动的风险(RR=4.45,95%CI:2.16~9.60,P<0.000 1,I2=25.0%)。结论:PFO封堵术能明显降低隐源性卒中患者脑卒中复发风险,但不能降低一过性脑缺血发作、死亡或大出血风险,且增加新发心房颤动的风险。
Objective:To compare the clinical efficacy and safety of closure of patent foramen ovale(PFO)with medical therapy in patients with cryptogenic stroke.Method:PubMed,Embase,Cochrane library,CNKI,Wanfang and Weipu databases were systematically searched for publications until April 1 st,2018 to identify the randomized controlled trials(RCTs)that compared the effects of PFO closure with medical therapy in patients with cryptogenic stroke.Stata 12.0 software was used to make meta analysis.Result:A total of 5 studies with 3 440 patients that fulfilled the criteria were included in the study.The pooled data indicated that PFO closure significantly reduced the risk of recurrent stroke(RR=0.43,95%CI:0.20-0.91,P=0.027,I2=58.8%).However,it did not significantly reduced the incidence of transient ischaemic attack(RR=0.78,95%CI:0.53-1.15,P=0.212,I2=0.0%),allcause mortality(RR=0.81,95%CI:0.39-1.66,P=0.559,I2=0.0%)and major bleeding(RR=0.97,95%CI:0.42-2.26,P=0.949,I2=34.6%).Moreover,PFO closure enhanced the incidence of newly detected atrial fibrillation(RR=4.45,95%CI:2.16-9.60,P<0.000 1,I2=25.0%).Conclusion:Closure of PFO can reduce the recurrence of stroke but increase the risk of atrial fibrillation in patients with cryptogenic stroke.
