Abstract
Cardiac contusions are being recognized with frequency. Among 507 patients with non-penetrating chest injuries, 210 had serial electrocardiograms sufficient to evaluate the heart. Forty-five of these 210 patients (21%) had cardiac contusions. These 45 patients and 3 others who were confirmed to have cardiac contusions at necropsy, comprise the 48 patients in this series. Life-indangering cardiac complications occurred in 14 (29%) of the 48 patients, and 4 patients died. The development of cardiac complications following cardiac contusions appears to have a significant relationship to the presence of shock, hypoxia and to factors related to the severity of multiple injuries. These observations have therapeutic implications in management of patients with cardiac contusions through prevention of hypovolemia and hypoxia and avoidance of fluid overload as well as treatment of specific cardiac complications.
