NCT06341361

Brief Summary

This study aims to compare the diagnostic accuracy of the fractional flow reserve (FFR) model derived by machine learning based on optical coherence tomography (OCT) exam after coronary artery stent implantation with the wire-based FFR.

Study Population

Among patients who underwent PCI for ischemic heart disease, those who underwent both OCT examination and pressure wire-based FFR after coronary artery stenting.

You may qualify if:

  • Patients who underwent stent implantation for ischemic heart disease
  • Patients who underwent both OCT examination and FFR using a pressure wire after PCI

You may not qualify if:

  • Poor OCT imaging quality
  • Patients with severe left ventricular dysfunction (\<30%)
  • Patients with severe valvular heart disease
  • Patients with a life expectancy of less than 1 year
