The study investigates the effectiveness of Quantitative Flow Ratio (QFR) as a method to evaluate non-culprit lesions (NCLs) in patients who have suffered a myocardial infarction (MI), comparing its performance to the traditional fractional flow reserve (FFR) method.
It involves a systematic review and meta-analysis of eight studies, comprising 713 patients and 920 vessels, yielding high diagnostic accuracy metrics for QFR, including an overall AUC of 0.941 and sensitivity of 87.3%.
The results indicate that QFR is a promising tool for assessing NCLs in MI patients, with recommendations for further multicenter studies to validate these findings.
