Of all, 98 (49.5%) patients were randomized to the QFR-guided PCI group, and 100 (50.5%) patients were included in the angiography-guided PCI group.Significantly more patients had a medical history of dyslipidemia and slightly better left ventricular ejection fraction (LVEF) (Table

Patient demographic, physical and medical parameters at admission and during the hospital stayAH – arterial hypertension; BP – blood pressure; DM – diabetes mellitus; HR – heart rate; LAD – left anterior descending artery; LCX – left circumflex artery; LM – left main artery; LVEF – left ventricular ejection fraction; MI – myocardial infarction; PCI – percutaneous coronary intervention; RCA – right coronary arteryDuring the 12-month follow-up (FU) period, 6 (6%) patients required additional non-culprit MI artery revascularization, which was decided not to treat according to visual estimation in the Angio group (Table 
Follow-up data of the study populationFU – follow up; LVEF – left ventricular ejection fraction; SASQ – Seattle angina score questionnaireWithin the 12-month period, 14 (7.07%) patients died, 2 (2.04%) in the QFR group and the remaining 12 (12%) in the Angio group. Survival analysis proved that patients in the Angio group had a more than 6-fold greater risk for death within the 12-month period after MI (OR 6.23, 95% CI 2.20-17.87, p = 0.006) (Fig.
