Safety and Long-Term Clinical Outcomes of Fractional Flow Reserve Guided Coronary Revascularisation

Abstract

Background: Increasingly, fractional flow reserve (FFR) is employed to assess coronary artery stenoses although there is limited real world long-term outcome data with a recent report questioning its safety. This study aimed to assess the in-hospital complications and clinical outcomes up to 10 years after FFR-guided revascularisation at a tertiary Australian hospital. Methods: The cohort comprised 274 consecutive patients undergoing FFR from 2010 to 2015 with follow-up to 2020. In-hospital complications and long-term outcomes were compared between patients with FFR≤0.80 and FFR>0.80. Major adverse cardiac events (MACE) comprised cardiac death, myocardial infarction (MI) and target vessel re..
