Grigorian A, et al. - Using the National Trauma Data Bank, researchers investigated if injuries demonstrating a higher transmission of force to the thorax, such as thoracic aortic injury (TAI), would have a higher association with blunt cardiac injury (BCI). Compared to TAI, sternal fracture (SF) after blunt trauma has a statistically higher correlation with BCI. However, the strongest independent risk factor for BCI is hemopneumothorax. They propose screening for BCI in all patients presenting after blunt chest trauma with high-risk features including hemopneumothorax, sternal fracture, esophagus injury, and TAI.
