Quantitative flow ratio-guided staged percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction.

ABSTRACT:

Background

The need for primary percutaneous coronary intervention (PCI) and staged PCI strategy for ST-segment elevation myocardial infarction (STEMI) with multivessel coronary disease is well documented. This study aimed to evaluate the efficiency, safety, and cost benefit of quantitative flow ratio (QFR)-guided staged PCI in patients with STEMI.

Methods

We conducted a retrospective study involving 2256 patients meeting STEMI criteria having at least one lesion (≥50 %) in non-infarct-related (NIR) arteries. These patients had undergone primary PCI for infarct-related (IR) arteries and staged PCI for NIR arteries. Patients were categorized into two groups based on the strategy guided either by QFR or quantitative coronary angiography (QCA) as determined by the clinicians du
