BACKGROUND: Use of transradial intervention (TRI) is becoming more popular, and recent studies suggest an advantage for TRI in high-risk patients presenting with acute coronary syndrome (ACS). The aim of our study was to describe current utilization and outcomes of transradial intervention (TRI) in real-world patients presenting with ACS. METHODS: Data were derived from the ACS Israeli Survey (ACSIS 2010), a nationwide prospective survey of patients presenting with ACS over a 2-month period. Follow-up was continued for up to 1 year. RESULTS: Of 1815 ACS patients undergoing coronary angiography, 613 (34%) underwent TRI, which was more likely to be employed among patients with lower-risk characteristics. Patients undergoing TRI had significantly lower 30-day mortality and in-hospital bleeding. On multivariate analysis, the risk of in-hospital major bleeding was reduced by 60% in patients undergoing TRI (P≤.04). However, no significant differences in other components of major adverse cardiac events or mortality were demonstrated at 30 days. All-cause mortality at 1 year was significantly lower among patients who underwent TRI. However, after multivariate adjustment, this effect was no longer significant. CONCLUSIONS: In our study of real-world patients, better TRI outcomes are related largely to lower baseline risk of patients allocated to this approach, suggesting that TRI may be underutilized in high-risk ACS patients.
