Abstract

Objectives: This 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. Background: Radial access for PCI has been studied considerably, but mostly in clinical trials. Methods: All 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. Results: Radial 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). Conclusions: The 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.
