Should fractional flow reserve be used to decide whether to perform percutaneous coronary intervention?

摘要

The use of an intracoronary hemodynamic technique, such as fractional flow reserve (ffr), to determine the severity of a stenosis, can help when deciding whether to perform percutaneous coronary intervention (PCI). In fact, using a cut-off FFR value of 0.75 to defer PCI is associated with favorable outcomes; however, studies have only focused on patients with single-vessel disease. OBJECTIVE To compare the major adverse cardiac event rate and cost of FFR-guided PCI with those of conventional PCI in patients with multivessel disease.
