Objectives
Narrative objectives1
Fractional flow reserve (FFR)-guided PCI for chronic coronary syndromes (CCS) is reported to improve the outcomes compared with angiography-guided PCI. However, cardiac-events still occur in FFR-deferral patients in long-term follow-up. Coronary computed tomography angiography (CTA)-defined high-risk-plaque (HRP) is known to relate future cardiac events. We hypothesized that CTA might identify plaque features linked to future cardiac events in deferral patients. To determine the predictive factors for future cardiac events in FFR-based deferral patients, we examine clinical features and plaque characteristics on CTA in the deferral lesions based on invasive FFR in consecutive patients with chronic coronary syndromes (CCS).

Assessment
Primary outcomes
Cardiac events were defined as a composite of cardiac death, non-fatal acute coronary syndrome (ACS), and ischemia-driven revascularization for patient-based analysis. Cardiac events were redefined as lesion-level ACS and lesion-level ischemia-driven revascularization.
Key secondary outcomes
Secondary endpoints are the individual components of the primary endpoints.

Key inclusion criteria
The inclusion criteria of this study are as follows 1) men and women aged over 20 years, 2) patients having CCS, 3) CTA was performed within 90 days before invasive coronary angiography with FFR pressure measurement.
Key exclusion criteria
The exclusion criteria are 1) patients with a history of coronary bypass grafting (CABG) because CABG changed local coronary flow dynamics, 2) patients with left-main disease, and 3) patients with FFR in stented vessels due to inability to estimate plaque morphology in the stented lesion by CTA.
