Study of the Natural History of FFR Guided Percutaneous Coronary Intervention
A Multicenter, Prospective Cohort to Evaluate the Natural History of FFR Guided Percutaneous Coronary Intervention
About 10,000 patients with FFR (Fractional Flow Reserve) will be enrolled and evaluated for the natural history of coronary lesions at 2 year clinical and imaging follow-up.
This is a multicenter, prospective cohort. About 10,000 patients with FFR will be enrolled at multi centers in Korea.
