ST elevation on ECGs can indicate acute myocardial infarction (AMI) or pneumothorax. Differentiating these conditions is crucial for timely and appropriate emergency medical treatment.

Area of Science:

  • Cardiology
  • Emergency Medicine
  • Pulmonology

Background:

  • ST elevation on a 12-lead electrocardiogram (ECG) is a key indicator of acute myocardial infarction (AMI).
  • However, ST elevation can also be present in other critical conditions, mimicking cardiac events.
  • Spontaneous pneumothorax is one such condition that can present with ECG changes.

Observation:

  • This report details three cases presenting with chest pain and ST elevation on ECG.
  • All three patients were diagnosed with pneumothoraces.
  • Only one of the three patients had an actual acute myocardial infarction.

Findings:

  • The diagnostic challenge lies in distinguishing between AMI and pneumothorax when both present with ST elevation.
  • Misdiagnosis can lead to inappropriate treatment, such as administering thrombolysis to patients without AMI.

  • One patient in this series received thrombolysis inappropriately due to the initial misinterpretation of ECG findings.

    • Implications:

    • Emergency physicians must be vigilant in differentiating ST elevation caused by pneumothorax from that caused by AMI.
    • Rapid and accurate diagnosis is essential, especially given the emphasis on "door-to-needle" times for AMI treatment.
    • Considering alternative diagnoses like pneumothorax in patients with chest pain and ST elevation can prevent iatrogenic harm and ensure appropriate care.
