JACC Cardiovasc Interv:在治疗有症状的股骨膜病变时,Zilver PTX支架似乎并不优于Misago支架——BATTLE试验1年研究结果

2020-11-13 MedSci原创 MedSci原创

BATTLE试验的主要目的是证明Zilver PTX支架比Misago支架在治疗股骨膜病变方面的临床优越性。但是,目前没有随机研究比较自膨式紫杉醇洗脱支架与裸金属支架在治疗股骨膜病变中的效果。

BATTLE试验的主要目的是证明Zilver PTX支架比Misago支架在治疗股骨膜病变方面的临床优越性。但是,目前没有随机研究比较自膨式紫杉醇洗脱支架与裸金属支架在治疗股骨膜病变中的效果,研究结果已在线发表于JACC Cardiovasc Interv
BATTLE是一项多中心随机对照试验,纳入股浅动脉或近端腘动脉有症状性(Rutherford类别2~5)新生病变的患者。主要终点是1年后无支架内再狭窄(ISR),再狭窄定义为目标病变处收缩期峰值速度指数>2.4。使用Kaplan-Meier方法评估2年随访期间免于ISR的时间-事件数据。
 
结果,2014年3月至2016年8月,186名患者入组;91人被分配到Misago组,90人分配到Zilver PTX组。Kaplan-Meier 1年免于ISR的估计值为:Misago为88.6%,Zilver PTX为91%(HR:1.2;95%置信区间[CI]:0.6~2.4;p = 0.64)。Misago和Zilver PTX的2年估计死亡率分别为6.4%和1.2%(HR:7.3;95% CI:0.9~59.3;p = 0.0632),通畅率分别为74.6%和78.8%(HR:1.2;95% CI:0.6~2.1;p = 0.62),靶病变血管重建率分别为14.4%和12.4%(HR:1.2;95% CI:0.5~2.8;p = 0.69)。
综上所述,该研究结果表明,在治疗有症状的股骨膜病变时,Zilver PTX支架在1年内免于ISR方面未能显示出优于Misago支架。
