Comparison of Vascular Access in STEMI

Distal radial access (DRA) has recently introduced and previous studies have demonstrated that it is feasible option, showing several advantages including less bleeding and access-site complications over proximal radial access (PRA). Previous study reported the feasibility of DRA as an alternative option for primary percutaneous coronary intervention (PCI) in STEMI patients without major complication. However, comparison study of each vascular access for primary PCI have not been conducted until now. Here, The investigators aim to compare the DRA, PRA and femoral access (FA), in terms of feasibility and safety, in patients with STEMI. This is a retrospective study with patients who underwent primary PCI for STEMI between March 2020 to May 2021. The primary outcome of this study is the access-site complication including major bleeding requiring transfusion or surgery, hematoma and arterial occlusion.
