(HealthDay News) – Adoption of radial access for percutaneous coronary intervention (r-PCI) has increased since 2007, and is associated with significantly lower vascular and bleeding complication rates, according to a study published in the June 11 issue of Circulation.

Dmitriy N. Feldman, MD, from the Weill Cornell Medical College in New York City, and colleagues conducted a retrospective study involving 2,820,874 PCI procedures from 1,381 sites to assess temporal trends in r-PCI. Outcomes were compared for r-PCI and transfemoral PCI.

The researchers found that the proportion of r-PCI procedures was 6.3% of total procedures from 2007–2012, and there was an increase in the proportion of r-PCI procedures from 1.2% in quarter 1 of 2007 to 16.1% in quarter 3 of 2012. Compared with transfemoral PCI, use of r-PCI correlated with significantly lower risk of bleeding (multivariate-adjusted odds ratio, 0.51) and of vascular complications (multivariate-adjusted odds ratio, 0.39). These reductions were seen across all subgroups of age, sex, and clinical presentation.

“This analysis of the largest contemporary multicenter PCI registry shows that there has been a 13-fold increase in r-PCI adoption over six years in U.S. clinical practice,” the authors write. “Wider adoption of r-PCI in interventional practice, particularly in higher-risk patients, presents an opportunity to potentially improve overall PCI safety.”
