Key result
Distal radial access significantly reduced the incidence of forearm radial artery occlusion compared to conventional transradial access (2.0% vs. 9.0%) in patients with STEMI undergoing primary PCI.
Why the study?
Distal radial access was introduced as an alternative to reduce radial artery occlusion risk, but its impact on early occlusion in STEMI patients undergoing primary PCI needed assessment.
Does distal radial access reduce the incidence of early forearm radial artery occlusion in STEMI patients undergoing primary PCI compared to conventional transradial access?

Absolute Event Rate: 2% vs 9%
p-value: p=0.030
In patients with STEMI undergoing primary PCI, distal radial access significantly reduces the incidence of early forearm radial artery occlusion and shortens hemostasis time compared to conventional transradial access.
Wang et al. (2022) conducted an RCT in ST-segment elevation myocardial infarction (STEMI) (n=200). Distal radial access (DRA) vs. Conventional transradial access (TRA) was evaluated on Incidence of forearm radial artery occlusion (RAO) evaluated by Doppler ultrasound before discharge (p=0.030). Distal radial access significantly reduced the incidence of forearm radial artery occlusion compared to conventional transradial access (2.0% vs. 9.0%) in patients with STEMI undergoing primary PCI.
