NCT06435728

Brief Summary

Patients with acute myocardial infarction were enrolled retrospectively. The fractional flow reserve (AccuFFR) and microcirculatory resistance index (AccuIMR) based on coronary angiography were analyzed, and the relationship between FFR and IMR and the prognosis of patients with acute myocardial infarction was analyzed

Study Population

Patients with STEMI who underwent primary PCI and were hospitalized at Peking University Third Hospital between January 2017 and March 2022.

You may qualify if:

  • Age of \>18 years;
  • Onset-to-treatment time of ≤12 h, meeting the diagnostic criteria for STEMI;
  • underwent primary PCI within 12 h of symptom onset and achieved successful PCI in the culprit vessel;
  • Availability of complete clinical data

You may not qualify if:

  • severe tortuosity and overlap of the target vessel;
  • poor-quality coronary angiography images;
  • missing two coronary angiography images \>25° apart
