Distal versus traditional radial access in patients undergoing emergency coronary angiography or percutaneous coronary intervention: a systematic review and meta-analysis.

Background: Distal radial access (DRA) is a well-tolerated and effective alternative to traditional radial access (TRA) for coronary procedures. However, the comparative value of these modalities remains unknown in the emergency setting, particularly in patients with ST-elevation myocardial infarction (STEMI).

Objective: To compare DRA versus TRA for emergency coronary procedures through a meta-analysis.
