Myocardial contusion, a traumatic cardiac injury, is best identified by significant blunt chest trauma. Normal serial ECGs and troponin I assays within 8 hours can exclude it, but monitoring for 48 hours is prudent for abnormal results.

Area of Science:

  • Cardiology
  • Trauma Medicine
  • Diagnostic Imaging

Background:

  • Myocardial contusion is a poorly defined term for traumatic cardiac injury.
  • Clinical questions persist regarding its diagnosis and necessary monitoring duration.

Purpose of the Study:

  • To answer clinical questions on diagnosing myocardial contusion.
  • To determine the required cardiac monitoring duration for patients with myocardial contusion.

Main Methods:

  • An evidence-based strategy was employed.
  • A PubMed search using Medical Subject Headings (MeSH) terminology was conducted.
  • Abstracts were selected based on predetermined criteria.

Main Results:

  • One meta-analysis, five descriptive reviews, and thirty-two other articles were reviewed.

  • Normal serial electrocardiograms (ECGs) and troponin I assays over 8 hours appear to exclude myocardial contusion.
  • Complications typically arise within 48 hours of injury.

    • Conclusions:

    • "Significant blunt chest trauma" is a more clinically useful term than myocardial contusion.
    • Patients with abnormal ECGs or troponin levels should be monitored for at least 48 hours post-injury.
