Longitudinal Myocardial Deformation as an Emerging Biomarker for Post-Traumatic Cardiac Dysfunction

Area of Science:

• Cardiology
• Trauma Medicine
• Medical Imaging

Background:

• Post-traumatic cardiac dysfunction is often missed by standard diagnostics.
• Early detection of myocardial impairment is crucial for managing polytrauma patients.
• Subclinical cardiac changes can precede overt symptoms and lead to long-term complications.

Purpose of the Study:

• To review the role of global longitudinal strain (GLS) in assessing cardiac dysfunction post-trauma.
• To highlight the limitations of conventional diagnostic methods.
• To explore GLS as a sensitive biomarker for early detection and management.

Main Methods:

• Review of literature on post-traumatic cardiac dysfunction.
• Analysis of speckle-tracking echocardiography (STE) for GLS measurement.
• Comparison of GLS with traditional cardiac assessment tools (ECG, LVEF, biomarkers).

Main Results:

• GLS demonstrates superior sensitivity in detecting subclinical myocardial impairment compared to LVEF.
• GLS is associated with increased risk of future cardiovascular events like arrhythmias and heart failure.
• Pathophysiology involves mechanical injury, inflammation, oxidative stress, and neuro-hormonal factors.

Conclusions:

• GLS is a valuable tool for early diagnosis, risk stratification, and monitoring of cardiac dysfunction in trauma patients.
• Integrating GLS with other biomarkers and AI may enhance precision in trauma cardiology.
• Further research can refine the application of GLS in clinical practice.
