Implication

May inform chest protector design to lower commotio cordis risk; leaves open translation from swine models to humans.

Key Points

To determine whether the mechanical properties of athletic chest protectors correlate with the occurrence of ventricular fibrillation caused by commotio cordis.
Measured the mechanical properties of chest protectors—including displacement, permanent deformation, stiffness, and area of pressure distribution—using a servo-hydraulic material tester.
Compared these material properties against ventricular fibrillation rates previously established in a swine impact model.
A decreased proportion of impacts causing ventricular fibrillation was significantly associated with an increase in the area of pressure distribution (R² = 0.59, p = 0.001).
Other evaluated mechanical parameters, including displacement, permanent deformation, and stiffness, demonstrated no significant association with reduced ventricular fibrillation rates.

Structured PICO

Does the area of pressure distribution of chest protectors reduce the occurrence of ventricular fibrillation in a swine model of commotio cordis?

Population

Established swine model for commotio cordis

Intervention

Chest protectors evaluated for mechanical properties (displacement, permanent deformation, stiffness, and area of pressure distribution)

Outcome

Occurrence of ventricular fibrillation (VF)surrogate

Increasing the area of pressure distribution in chest protectors may reduce the risk of ventricular fibrillation from commotio cordis.
