ST elevation: Differential diagnosis and caveats. A comprehensive review to help distinguish ST elevation myocardial...

Area of Science:

• Cardiology
• Electrocardiography
• Emergency Medicine

Background:

• Acute ST segment elevation myocardial infarction (STEMI) requires urgent revascularization.
• Conditions mimicking STEMI on ECG may lead to inappropriate interventions.
• Accurate ECG interpretation is vital for differentiating ischemic from non-ischemic causes.

Purpose of the Study:

• To review ECG features of non-ischemic conditions that mimic STEMI.
• To aid clinicians in early recognition and prevention of misdiagnosis.
• To improve treatment strategies for patients with ST segment elevation on ECG.

Main Methods:

• Narrative clinical review of existing literature.
• Focus on ECG characteristics of various non-ischemic ST elevation mimics.
• Discussion of differential diagnostic criteria.

Main Results:

• Identified key ECG patterns distinguishing non-ischemic mimics from true STEMI.
• Highlighted conditions such as pericarditis, early repolarization, and Brugada syndrome.
• Emphasized the importance of clinical context in ECG interpretation.

Conclusions:

• Distinguishing non-ischemic ST elevation from STEMI on ECG is critical.
• Understanding mimics prevents unnecessary invasive procedures.
• Accurate diagnosis improves patient management and outcomes.
