Sex and racial disparities in fractional flow reserve-guided percutaneous coronary intervention utilization: a 5-year national experience

FAME (Fractional Flow Reserve versus Angiography for Multivessel Evaluation) and FAME-2 trials have demonstrated the improved outcomes with fractional flow reserve (FFR)-guided percutaneous coronary interventions (PCI) and established the essential role of FFR to reduce major cardiovascular events (1,2). However, FFR adoption is not up to the mark in many centers and the data are almost non-existent regarding racial and sex disparities in FFR-guided PCI utilization. Therefore, we proposed to assess the trends of racial and sex disparities in FFR-guided PCI utilization over the 5-year period between 2010 and 2014.
