Intravascular modality‐guided versus angiography‐guided percutaneous coronary intervention in acute myocardial infarction
Background Few data are available for current usage patterns of intravascular modalities such as intravascular ultrasound (IVUS), optical coherence tomography (OCT), and fractional flow reserve (FFR) in acute myocardial infarction (AMI). Moreover, patient and procedural‐based outcomes related to intravascular modality guidance compared to angiography guidance have not been fully investigated yet. Methods We examined 11,731 patients who underwent percutaneous coronary intervention (PCI) from the Korea AMI Registry–National Institute of Health database. Patient‐oriented composite endpoint (POCE) was defined as all‐cause death, any infarction, and any revascularization. Device‐oriented composite endpoint (DOCE) was defined as cardiac death ...
