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?
Circulation
January 2025
Department of Cardiology, The 2nd Affiliated Hospital of Harbin Medical University, Harbin, China (J.D., J.Z., X.X., Y.C., S.S., S.L., L.C., Y.W., L.L., R.G., D.H., X.M., R.Z., H.Y., T.C., J.T., X.L., S.J., J.H., C.F.B.Y.).
Background: Patients with acute myocardial infarction and angiographically obstructive non-culprit lesions are at high risk for recurrent major adverse cardiac events (MACEs). However, it remains largely unknown whether events are due to stenosis severity or due to the underlying high-risk lesion morphology.
Methods: Between January 2017 and December 2021, 1312 patients with acute myocardial infarction underwent optical coherence tomography of all the 3 main epicardial arteries after successful percutaneous coronary intervention.

Myocardial bridging is a frequent anomaly of the heart in humans and other animals. A myocardial bridge is typically characterized by the systolic narrowing seen with traditional catheter angiography, but this abnormality is not by itself a sign of ischemia or the need for intervention. In particular, transient spontaneous angina must be corroborated by reproducible narrowing during acetylcholine testing; this narrowing occurs during resting conditions and is responsive to nitroglycerin administration.

February 2024
CAPITAL Research Group, University of Ottawa Heart Institute, Ottawa, Ontario, Canada.
Background: Type I myocardial infarction (T1MI) or type II myocardial infarction (T2MI) have different underlying mechanisms; however, in the setting of cardiogenic shock (CS), it is not understood if patients experience resultantly different outcomes. The objective of this study was to determine clinical features, biomarker patterns, and outcomes in these subgroups.
Methods: Patients from the CAPITAL-DOREMI trial presenting with acute myocardial infarction-associated CS (n = 103) were classified as T1MI (n = 61) or T2MI (n = 42).
What Are These Anterior T Waves?: A High-Risk Ischemic Pattern That Should Be Recognized.
JACC Case Rep

Cardiology Department, University Hospital Doctor Negrín, Las Palmas de Gran Canaria, Spain.
An 80-year-old woman with history of intermittent chest pain presented with a new self-limited episode. A 12-lead electrocardiogram was performed while she was asymptomatic, showing large T waves in V to V. We report a not so known electrocardiographic pattern that can be particularly valuable for identifying patients at high risk of extensive myocardial infarction and its subsequent complications.
