Abstract

Background: Coronary computed tomography angiography (cCTA)-derived fractional flow reserve (FFRCT) is a promising diagnostic method for the evaluation of coronary artery disease (CAD). However, clinical data regarding FFRCT in Japan are scarce, so we assessed the clinical impact of using FFRCT in a Japanese population. Methods and Results: The ADVANCE registry is an international prospective FFRCT registry of patients suspected of CAD. Of 5,083 patients, 1,829 subjects enrolled from Japan were analyzed. Demographics, symptoms, cCTA, FFRCT, treatment strategy, and 90-day major cardiovascular events (MACE) were assessed. Reclassification of treatment strategy between cCTA alone and cCTA+FFRCT occurred in 55.8% of site investigations and in 56.9% in the core laboratory analysis. Patients with positive FFR (FFRCT ≤0.80) were less likely to have non-obstructive disease on invasive coronary angiography than patients with negative FFR (FFRCT >0.80) (20.5% vs. 46.1%, P=0.0001). After FFRCT, 67.0% of patients with positive results underwent revascularization, whereas 96.1% of patients with negative FFRCT were medically treated. MACE occurred in 5 patients with positive FFRCT, but none occurred in patients with negative FFRCT within 90 days. Conclusions: In this Japanese population, FFRCT modified the treatment strategy in more than half of the patients. FFRCT showed potential for stratifying patients suspected of CAD properly into invasive or non-invasive management pathways.
