Long-Term Prognostic Implications of Non-Culprit Lesions in Patients Presenting With an Acute Myocardial Infarction: Is It the Angiographic Stenosis Severity or the Underlying High-Risk Morphology?

Long-Term Prognostic Implications of Non-Culprit Lesions in Patients Presenting With an Acute Myocardial Infarction: Is It the Angiographic Stenosis Severity or the Underlying High-Risk Morphology?

In patients with acute myocardial infarction (AMI), angiographic ≥50% stenosis in non-culprit lesions and a higher number of thin-cap fibroatheroma (TCFA) detected on OCT were associated with an increased risk of major adverse cardiovascular events (MACE: cardiac death, non-fatal myocardial infarction, and unplanned revascularization).
