Blunt Cardiac Injury in Trauma Patients with Thoracic Aortic Injury

Abstract EN

Trauma patients with thoracic aortic injury (TAI) suffer blunt cardiac injury (BCI) at variable frequencies.

This investigation aimed to determine the frequency of BCI in trauma patients with TAI and compare with those without TAI.

All trauma patients with TAI who had admission electrocardiography (ECG) and serum creatine kinase-MB (CK-MB) from January 1999 to May 2009 were included as a study group at a level I trauma center.

BCI was diagnosed if there was a positive ECG with either an elevated CK-MB or abnormal echocardiography.

There were 26 patients (19 men, mean age 45.1 years, mean ISS 34.4) in the study group; 20 had evidence of BCI.

Of 52 patients in the control group (38 men, mean age 46.9 years, mean ISS 38.7), eighteen had evidence of BCI.

There was a significantly higher rate of BCI in trauma patients with TAI versus those without TAI (77% versus 35%, P<0.001).
