ObjectivesThis study sought to determine the utilization and outcomes for radial access for percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction (STEMI) in common practice.BackgroundRadial access for PCI has been studied considerably, but mostly in clinical trials.MethodsAll patients undergoing PCI for STEMI in 2009 to 2010 in New York were studied to determine the frequency and the patient-level predictors of radial access. Differences in in-hospital/30-day mortality between radial and femoral access were also studied.ResultsRadial access increased from 4.9% in the first quarter of 2009 to 11.9% in the last quarter of 2010. Significant independent predictors were higher body surface area, non-Hispanic ethnicity, Caucasian race, stable hemodynamic state, ejection fraction <30% and ≥50% onset of STEMI from 12 to 23 h before the index procedure, and peripheral vascular disease. Mortality was not related to access site after adjustment for covariates (for radial vs. femoral access, adjusted odds ratio: 0.86, 95% confidence interval: 0.59 to 1.25), but the radial access site was trending toward lower mortality for the 9 hospitals that used it for more than 10% of their patients (adjusted odds ratio: 0.61, 95% confidence interval: 0.36 to 1.02).ConclusionsThe use of a radial access site for PCI in STEMI patients increased between 2009 and 2010, but was still infrequent in 2010, and was used for lower-risk STEMI patients. There was no significant difference in mortality by access site, but there was a trend toward a mortality advantage for patients with a radial access site among hospitals that used it relatively frequently.Copyright © 2014 American College of Cardiology Foundation.
