Sex-related differences in fractional flow reserve-guided treatment.
BACKGROUND Sex-specific differences affect the evaluation, treatment, and prognosis of coronary artery disease. We tested the hypothesis that long-term outcomes of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) are different between women and men. METHODS AND RESULTS Consecutive 1090 patients, referred for PCI and undergoing FFR measurements at the Mayo Clinic b...
متن کاملFractional Flow Reserve
Traditionally, coronary artery disease was assessed using coronary angiographic guidance. Significant lesions were determined by the coronary angiographer. However, interobserver variability showed a significant limitation of interpretation of coronary angiography. Stent deployment and apposition were also evaluated based on angiographic appearance only. Risk factors for stent thrombosis and in...
متن کامل“Virtual” (Computed) Fractional Flow Reserve
Ma Fractional flow reserve (FFR) is the “gold standard” for assessing the physiological significance of coronary artery disease during invasive coronary angiography. FFR-guided percutaneous coronary intervention improves patient outcomes and reduces stent insertion and cost; yet, due to several practical and operator related factors, it is used in <10% of percutaneous coronary intervention proc...

n engl j med 372;1 nejm.org january 1, 2015 94 difference. The observed loss of FEV1 was neither a time-dependent nor a dose-dependent effect in the withdrawal group, as compared with the maintenance group. A difference of 38 ml between groups became apparent only after the final step of inhaled glucocorticoid withdrawal and did not change to a meaningful extent thereafter. Singanayagam et al. ...
متن کاملEnd-diastolic fractional flow reserve: comparison with conventional full-cardiac cycle fractional flow reserve.
BACKGROUND Diastolic fractional flow reserve (dFFR) has been shown to be highly sensitive for detection of inducible myocardial ischemia. However, its reliance on measurement of left-ventricular pressure for zero-flow pressure correction, as well as manual extraction of the diastolic interval, has been its major limitation. Given previous reports of minimal zero-flow pressure at end-diastole, w...
