    Posttraumatic myocardial dysfunction is common in multisystem trauma patients, often affecting the right ventricle. Radionuclide ventriculography (RNV) effectively identifies and monitors this cardiac dysfunction.

    Area of Science:

    • Cardiology
    • Trauma Medicine
    • Diagnostic Imaging

    Background:

    • Multisystem trauma can lead to myocardial dysfunction.
    • Early detection of cardiac dysfunction is crucial for patient outcomes.

    Purpose of the Study:

    • To evaluate posttraumatic myocardial dysfunction in trauma patients.
    • To assess the utility of radionuclide ventriculography (RNV) in identifying cardiac dysfunction.

    Main Methods:

    • Combined dynamic first-pass and electrocardiographically (ECG) gated radionuclide ventriculography (RNV) was used.
    • 54 patients with multisystem trauma, including blunt chest injury, were studied.

    Main Results:

    • 48% of patients showed ventricular wall motion abnormalities, predominantly in the right ventricle (92%).

  • Right ventricular ejection fraction was significantly lower in patients with abnormalities.
  • No significant correlation was found between ECG changes or injury type and cardiac dysfunction.

    • Conclusions:

    • Combined first-pass and ECG-gated RNV is a valuable tool for diagnosing posttraumatic cardiac dysfunction.
    • Follow-up studies indicated significant improvement in cardiac function within 3 weeks.
