研究目的: |
本项目旨在通过多中心、前瞻性、随机对照研究,对比dTRA与cTRA在高出血风险患者行经皮冠状动脉介入诊疗中的应用效果,验证dTRA在减少穿刺部位出血、缩短止血和压迫时间、降低桡动脉闭塞率等方面的优势,为优化冠脉介入路径提供循证依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
This project aims to conduct a multicenter, prospective, randomized controlled trial comparing the efficacy and safety of distal transradial access (dTRA) versus conventional transradial access (cTRA) in patients with high bleeding risk (HBR) undergoing percutaneous coronary intervention (PCI). The study seeks to validate the superiority of dTRA in reducing access-site bleeding, shortening hemostasis and compression time, and lowering radial artery occlusion rates, thereby providing evidence-based rationale for optimizing coronary access strategies in high-risk populations. |

|
盲法: |
由于干预措施涉及不同的穿刺部位(远端桡动脉 vs 传统桡动脉),术者和患者无法设盲。但结局评估者设盲:主要终点(术后24小时皮下血肿程度,改良EASY评价系统)由两名不知晓分组情况的研究医师独立评估;桡动脉超声检查由不知晓分组的超声医师盲法测量,图像上传中央平台后由盲法判读人员评估。 |
|
Blinding: |
Due to the nature of the intervention involving different puncture sites (distal transradial vs conventional transradial), blinding of operators and patients is not feasible. However, outcome assessors will be blinded to group allocation: the primary endpoint (degree of subcutaneous hematoma at 24 hours post-procedure assessed by modified EASY classification) will be evaluated independently by two physicians unaware of group assignment; radial artery ultrasound examinations will be performed and interpreted by blinded sonographers, with images uploaded to a central platform for blinded adjudication. |
