ST segment elevations typically indicate heart attacks, but other conditions like pericarditis can mimic them. Differentiating these causes is crucial for appropriate emergency department treatment and avoiding unnecessary therapies.

Area of Science:

  • Cardiology
  • Emergency Medicine
  • Electrocardiography

Background:

  • ST segment elevation on an electrocardiogram (ECG) is a primary indicator for acute myocardial infarction (heart attack) in emergency departments.
  • This ECG finding often serves as the inclusion criterion for administering thrombolytic therapy to restore blood flow.

Observation:

  • This study presents three cases highlighting that ST segment elevations can arise from conditions other than acute myocardial infarction.
  • Differential diagnoses for ST segment elevation include acute pericarditis and normal electrocardiogram variants.
  • These alternative conditions do not warrant thrombolytic therapy.

Findings:

  • Acute substernal pain with ST segment elevation requires careful evaluation beyond just acute myocardial infarction.

  • The presented cases demonstrate that conditions like acute pericarditis can present with ST segment elevations, mimicking heart attacks.
  • Accurate differentiation is essential to guide appropriate medical intervention.

    • Implications:

    • Emergency department physicians must be adept at identifying diverse causes of ST segment elevation during patient triage.
    • Misinterpreting ST segment elevations can lead to the inappropriate administration of thrombolytic therapy.
    • Timely and accurate diagnosis based on ECG interpretation is critical for patient outcomes in emergency settings.
