Summary

The study intends to provide new data on whether the noval method using quantitative flow ratio could assess microvascular dysfunction based on the previous study EARLY-MYO-QFR-I.

Conditions

  • ST Segment Elevation Myocardial Infarction

Interventions

DIAGNOSTIC_TEST

Computation of quantitative flow ratio

After stents were implanted whenever technically possible in the STEMI patients, the investigators created a temporary artificial stenosis inside the stent by partially inflating a balloon catheter during pharmacologic hyperemia. Computation of QFR was performed offline, using AngioPlus system(Pluse medical imaging technology, Shanghai, China). In the first step, 2 diagnostic angiographic projections with the artifical stenosis, at least 25° apart, were selected and 3D reconstruction of the interrogated vessel without its side branches was performed. Then, the software computed the QFR.
