STENOSIS
A total of 198 patients admitted with STEMI and at least one intermediate (35–75%) diameter stenosis other than the culprit artery between July 2020 and June 2021 were prospectively included in this single-center study. All patients were randomized into one of two groups (1 - QFR-guided PCI; 2 - visual-estimation-only guided PCI). A 12-month follow-up with echocardiography, exercise stress test, and quality of life evaluation was performed in all included patients. For the QOF evaluation, the Seattle Angina Score Questionnaire was chosen. Statistical analysis was performed using the Kolmogorov–Smirnov test, Student’s t-test, Mann–Whitney U test, Pearson’s chi-squared test and Kaplan–Meier estimator.
