研究目的:

评估与DES对比,DCB治疗STEMI患者的长期安全性和疗效。  

Objectives of Study:

To evaluate the long-term safety and efficacy of DCB in patients with STEMI as compared with DES.

药物成份或治疗方案详述:

对符合入排标准的患者随机分配到两组,而后行血栓抽吸。DCB 组靶病变预处理方法,依据OCT 检查分类而决定,包括半顺应或非顺应性球囊、切割球囊, 球囊直径与血管直径比例为 0.8~1.0︰1。DES 组则遵循现行指导原则进行预处理。如果预扩张后造影残余狭窄≤30%且血流 TIMI 分级>2 级,未见 C 型及以上夹层,则分别行 DCB 或 DES 治疗。 如DCB 组患者不符合上述标准则行支架植入治疗。DCB 治疗组中DCB 的直径选择与预处理球囊相同直径,DCB 两端应超出病变 3mm。扩张压力 8~10atm,持续 60s(TBD)。治疗后即刻造影,如果显示残余狭窄≤30%且血流 TIMI 分级为 3 级,未见 C 型及以上夹层, 则认为治疗成功。而后 DCB 组在 15 分钟后行 QFFR/CTFFR 检查,确定血流功能情况,如<0.80, 则认为 DCB 治疗失败,应在 OCT 指导下置入补救性 DES。DES 组病人,如支架边缘出现严重夹层,应置入补救性DES。 

Description for medicine or protocol of treatment in detail:

Patients who met the criteria for admission were randomly assigned to two groups and then thrombotic aspiration was performed.Target lesions in the DCB group were pretreated according to OCT classification, including semi-compliant or non-compliant balloons and cut balloons. The ratio of balloon diameter to vascular diameter was 0.8 ~ 1.0:1.DES group followed the current guidelines for preprocessing.If residual stenosis <= 30% after pre-dilatation and blood flow TIMI grade > grade 2, no c-type or above interlayer is found, then DCB or DES will be performed respectively.If patients in the DCB group did not meet the above criteria, stent implantation was performed.The diameter of DCB in the DCB treatment group was the same as that of the pretreatment balloon, and both ends of DCB should exceed the lesion by 3mm.The expansion pressure was 8 ~ 10atm and lasted 60s (TBD).Immediately after treatment, angiography is performed. If residual stenosis is shown to be <= 30% and TIMI grading of blood flow is grade 3, and no c-type or above interlayer is found, the treatment is considered to be successful.Then, the DCB group underwent QFFR/CTFFR examination 15 minutes later to determine the blood flow function. If <0.80, DCB treatment was considered to have failed and remedial DES should be placed under THE guidance of OCT. Patients in the DES group, if there is a severe dissection at the edge of the stent, a remedial DES should be placed.
