Women FiRST: Fractional Flow Reserve and Instantaneous Free-wave Ratio Revascularization Strategies in Women

The aim of this data repository is to evaluate the impact of gender differences on fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR). These findings will be used to refine the recommendations of the role of physiologic assessment using FFR and iFR-guided percutaneous coronary interventions (PCI) in women. Data will be stored long term for future undefined analyses, including outcomes in women presenting with ischemic syndromes. Gender comparisons will made from archival and published research data sets from studies comprised up to 80% men.
