NCT05250557N/ARecruitingUpdate OverdueUpdated 52mo ago · Completion was 6mo agoPrognostic Impact of Lesion-specific Hemodynamic Index and Disease Characteristics in Patients With Coronary Artery Disease Assessed by Fractional Flow Reserve
In Brief
An observational study evaluating Fractional flow reserve for Coronary Artery Disease. Currently recruiting, targeting 2,429 participants across 1 site.
Signals
Detailed Summary
The investigators aim to investigate the additive prognostic value of lesion-specific hemodynamic index such as ΔFFR, non-hyperemic pressure ratio such as RFR, over % diameter stenosis and FFR according to treatment strategy, and to find the prognostic implications of post-PCI FFR after adjustment of various clinical and disease characteristics, and to construct a comprehensive risk prediction model for post-PCI outcomes.
Study Details
Timeline
Interventions
Physiologic assessment includes Δ FFR (lesion-specific) and FFR (vessel-specific) measurement. Δ FFR is defined as a pressure step up across the lesion. Coronary angiography and physiologic assessment will be analyzed by an independent core laboratory (Seoul National University Hospital, Clinical Trial Center, Seoul, South Korea).
