Low vessel fractional flow reserve after percutaneous coronary intervention to fail
Both fractional flow reserve and non-hyperemic pressure ratios are widely used to assess the hemodynamic importance of intermediate coronary artery lesions. While the specific merits of each of these physiological indices have been mainly validated in a pre-percutaneous coronary intervention (PCI) setting, there is increasing interest in the use of either fractional flow reserve or non-hyperemic pressure ratios to assess the direct impact of stent placement on post percutaneous coronary intervention physiology.
The FAST Outcome study is a retrospective cohort study in which patients were recruited from the P- SEARCH registry. The study is published in International Journal of Cardiology. The study aimed to assess the prognostic value of post percutaneous coronary intervention and the incidence of target vessel failure, a composite endpoint of cardiovascular death, spontaneous target vessel myocardial infarction and target vessel revascularization at 5 years follow-up.
