Compared with conventional transradial access (TRA), distal radial access (DRA) is rarely used for percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) and may be beneficial to prevent radial artery occlusion (RAO). We aimed to evaluate the incidence of RAO between DRA and TRA 24 h after primary PCI in patients with STEMI.
This is a single-center, open-label, prospective, randomized controlled trial conducted at Beijing Luhe Hospital, China, between January 2022 and July 2023. Five hundred and twenty patients (mean age: 61.3 ± 13.0 years; 81% male) with STEMI were randomly assigned to the DRA (n = 260) or TRA (n = 260) group. Primary PCI was performed using the radial artery access assigned study group. The primary endpoint was the rate of RAO assessed using Doppler ultrasound 24 h after primary PCI. Secondary outcomes included time taken for sheath insertion, access success rate, hemostasis time, fluoroscopy time, radiation dosage, and access-related complications.
The incidence of RAO was significantly lower in the DRA group than that in the TRA group (1.9% vs. 8.5%, P = 0.001). Access was successful in 94.6% of patients, and the crossover rate was 5.4% in both groups. The median time taken for sheath insertion was significantly longer (133 s vs. 114 s, P = 0.009), whereas the mean hemostasis time was shorter (209 ± 71 min vs. 372 ± 70 min, P < 0.001) in the DRA group. The incidence of modified Early Discharge After Transradial Stenting of Coronary Arteries (mEASY) ≥ II hematoma was lower in the DRA group (0.8% vs. 3.5%, P = 0.033). However, there was no significant difference in fluoroscopy time, radiation dosage, or access-related complications.
In patients with STEMI undergoing primary PCI, compared with TRA, DRA prevented RAO 24 h postoperatively and was associated with shorter hemostasis time and a lower incidence of mEASY ≥ II hematoma.

与传统经桡动脉入路(TRA)相比,桡动脉远段入路(DRA)在ST段抬高型心肌梗死(STEMI)患者的经皮冠状动脉介入治疗(PCI)中很少使用,可能有助于预防桡动脉闭塞(RAO)。我们旨在评估STEMI患者在直接PCI术后24小时DRA与TRA之间RAO的发生率。
这是一项于2022年1月至2023年7月在中国北京潞河医院进行的单中心、开放标签、前瞻性、随机对照试验。520例STEMI患者(平均年龄:61.3±13.0岁;81%为男性)被随机分配至DRA组(n = 260)或TRA组(n = 260)。使用分配至研究组的桡动脉入路进行直接PCI。主要终点是直接PCI术后24小时使用多普勒超声评估的RAO发生率。次要结局包括鞘管插入时间、入路成功率、止血时间、透视时间、辐射剂量和与入路相关的并发症。
DRA组的RAO发生率显著低于TRA组(1.9%对8.5%,P = 0.001)。94.6%的患者入路成功,两组的交叉率均为5.4%。DRA组鞘管插入的中位时间显著更长(133秒对114秒,P = 0.009),而平均止血时间更短(209±71分钟对372±70分钟,P < 0.001)。DRA组改良的经桡动脉冠状动脉支架置入术后早期出院(mEASY)≥II级血肿的发生率更低(0.8%对3.5%,P = 0.033)。然而,透视时间、辐射剂量或与入路相关的并发症方面无显著差异。
在接受直接PCI的STEMI患者中,与TRA相比,DRA可预防术后24小时的RAO,且止血时间更短,mEASY≥II级血肿的发生率更低。
