Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We retrospectively enrolled STEMI patients who underwent PCI in Peking University Third Hospital. The fractional flow reserve (AccuFFR) and microcirculatory resistance index (AccuIMR) based on coronary angiography were obtained by analyzing the coronary angiography images. The prognosis of patients was obtained by searching inpatient and outpatient systems and telephone follow-up. The relationship between AccuFFR, AccuIMR and prognosis was statistically analyzed
