Key result
Persistent ST elevation mimics AMI but reflects a chronic 10-year pattern driven by structural remodeling.
Why the study?
Non-ischemic causes of ST-segment elevation may complicate diagnostic decision-making, especially in elderly patients presenting with acute non-cardiac illnesses.
Population
A 95-year-old woman with COVID-19–associated and aspiration pneumonia
Design

May warrant caution against assuming acute ischemia in COVID-19; leaves open chronic remodeling as cause pending larger studies.
Case Report (n=1)
Persistent ST-segment elevation can mimic acute myocardial infarction and may reflect chronic underlying structural myocardial substrate, emphasizing the need for clinical and longitudinal ECG correlation.
Aizawa et al. (2026) conducted a case report in Persistent ST-segment elevation mimicking ST-elevation myocardial infarction (n=1). Persistent ST-segment elevation was evaluated. Persistent ST-segment elevation in a 95-year-old woman mimicked acute myocardial infarction but was a chronic pattern present for over 10 years, likely reflecting underlying structural remodeling.
