Официальное название
Prospective Evaluation of Coronary Artery Disease in Women Presenting With Cardiac Ischemia: an Anatomic and Physiologic Study Comparing Fractional Flow Reserve (FFR) and Instantaneous Free-wave Ratio (iFR) on Cardiac Catheterization With Findings of Inducible Ischemia on Non-invasive Stress Imaging
Обзор
A real world study to evaluate outcomes in women based on guideline identified fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) cutoffs for ischemia (ischemia defined as FFR ≤ 0.80 and iFR ≤ 0.89).
Подробное описание
The WOMEN FiRST (FFR iFR Revascularization Strategies Trial) study collects information from enrolled subjects to create a data repository. The data will be used to further elucidate recommendations for PCI of angiographically intermediate lesions (30-90% stenosis) in epicardial lesions in women by comparing FFR and iFR findings to findings of inducible ischemia on existing non-invasive stress imaging studies. Gender comparisons will also be made from archived and published research data sets from studies comprised up to 80% men. Data will also be stored long term for use in future undefined analyses.
Вмешательства
- Другое No study intervention
