The Non-Linear Mathematics of Death and Vascular Access
In this issue of Circulation, the British Cardiovascular Intervention Society (BCIS) National Registry presents compelling data on trends and outcomes with respect to radial versus femoral artery access for percutaneous coronary intervention (PCI)1; 448,853 patients in the United Kingdom underwent PCI between 2005 and 2012 and radial access grew 3 fold. This is not the first BCIS study to document this march towards radial access dominance or the association of radial access with improved outcomes2. Nor is this the largest temporal trends study demonstrating significant growth of the radial strategy: the National Cardiovascular Database Registry (NCDR) studied over 2.8 million patients in the United States and documented a growth in radial access from 1.2 to 16.1% of all PCI procedures from 2007-20123; like the current BCIS study, the NCDR analysis also demonstrated regional heterogeneity in growth and improved outcomes among patients receiving radial as opposed to femoral access.
