The Predictive Effects of ECG and QFR in the Detection of Microvascular Obstruction in Patients With STEMI After PPCI

In STEMI patients after PPCI, QFR exhibited a superior predictive capability for the occurrence of MVO. STR demonstrated a reliable predictive ability for MVO/LV mass in MVO populations, and exhibited correlations with heart function and infarct size during long-term follow-up.
