BackgroundThe objective of the study is to investigate diagnostic and clinical processes performed for cardiac contusion in patients with blunt thoracic trauma.MethodsThis study was conducted retrospectively on 65 patients admitted with isolated blunt thoracic trauma to the Emergency Medicine Department. The CT images, the cardiac enzyme levels, the periodic 4-h follow-up electrocardiography (ECGs) in the emer-gency department, and the results of echocardiography, performed at admission and when required according to the clinical status, were investigated. The 1-h and 4-h high-sensitivity troponin I levels were studied, and values above 0.04 ng/ml were considered as positive.ResultsSixty-five patients with isolated thoracic trauma were included in the study, 23 (35.38%) had pulmonary and cardiac contu-sions both. In 23 (35.38%) patients, pulmonary contusion had been present, and cardiac contusion had not been identified at the initial evaluation. However, during clinical follow-up, troponin became positive, dysrhythmia developed, and the trauma affected the heart in four of these patients. In six (9.24%) patients, cardiac contusion was identified without pulmonary contusion. In 13 (20%) patients, no cardiac or pulmonary contusion was identified. troponin elevation was detected in 10 patients without a diagnosis of cardiac contusion who had a pulmonary contusion, hemothorax, and/or pneumothorax at the time of hospital admission and then with normal troponin levels at 4-h control. We found that there was a statistical agreement between cardiac contusion and troponin-ECG results at 4th h.ConclusionWe advise that all blunt thoracic trauma patients should be screened for cardiac contusion by continuous ECG monitoring and troponin levels.
