Brief Summary: The study intends to provide important data on whether the noval method using quantitative flow ratio could predict microvascular dysfunction.
Detailed Description: Microvascular dysfunction (MVD) is a serious complication of PCI, which happens frequently after STEMI and always correlates with a poor prognosis. However, precise and simplified assessment of MVD is difficult, especially in the acute phase of STEMI patients. Resent studies suggested that FFR could be overestimated when MVD exists. But whether the overestimated value of FFR caused by CMR defined MVO could reflect microcirculation function is still unclear.

This study is a retrospective study using STEMI patients with TFG 2/3 of the infarct vessel on initial angiography and presumed culprit lesion ≥50% as the population. Contrast-enhanced CMR was performed 5 days after PCI as the reference standard.
