Brief Summary

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

The goal of this observational study is to learn about in STEMI with Primary PCI Patients. The main questions it aims to answer are:

* To determine the value of AMR in predicting the long-term clinical prognosis of patients with STEMI after PPCI, and to find the best cut-off value.
* Analyze the factors of PPCI affecting AMR and explore the effective measures of PPCI microcirculation protection.

Radiographic images of STEMI receiving primary PCI treatment in several chest pain centers in China will be included. The last image of the infarct-related vessel will be used as a target to calculate its AMR. The relationship between AMR and long-term clinical prognosis was analyzed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

diagnostic cohort/derivation cohort

The diagnostic/derivation cohort included STEMI patients who underwent PCI within 12 hours and CMR. The optimal AMR cutoff value for diagnosing CMD using CMR was determined by analyzing ROC curves.

No interventions assigned to this group

prognostic cohort/validation cohort

The prognostic cohort enrolled STEMI patients who underwent PPCI within 12 hours. All patients were followed up for at least 1 year.

No interventions assigned to this group
