Conclusion
ST-elevation myocardial infarction
The QFR is a noninvasive coronary physiology evaluation method that is accurate for STEMI patients and can be performed by any qualified team member. The use of QFR for patients with ST-elevation myocardial infarction significantly reduced the mortality rate and revascularization at the 12-month follow-up. The patients who underwent PCI guided by the QFR had lower physical activity limitations during their daily activities.
