Key result
Seatbelt wearing in fatal frontal impact collisions did not prevent heart rupture, which was usually caused by crushing against the steering wheel and involved a ventricle in 75.5% of cases.
Why the study?
Does seatbelt use alter the location or mechanism of fatal heart rupture in traffic collisions?
Population
4,169 victims of traffic collisions fatally injured between 1972 and 1985, of which 1,121 died primarily of…

Seatbelt use does not prevent fatal heart rupture in frontal collisions; leaves open whether vehicle design changes could reduce ventricular injuries.
Case-Control (n=94)
Does seatbelt use alter the location or mechanism of fatal heart rupture in traffic collisions?
Fatal heart ruptures in seatbelt wearers during frontal collisions are typically caused by crushing against the steering wheel, similar to unbelted victims, and most often involve the ventricles.
SANTAVIRTA et al. (1992) conducted a case-control in Fatal traffic collisions with heart rupture (n=94). Seatbelt wearing vs. Unbelted was evaluated on Site and mechanism of cardiac injury. Seatbelt wearing in fatal frontal impact collisions did not prevent heart rupture, which was usually caused by crushing against the steering wheel and involved a ventricle in 75.5% of cases.
