METHODS: This 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 emergency 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. RESULTS: Sixty-five patients with isolated thoracic trauma were included in the study, 23 (35.38%) had pulmonary and cardiac contusions 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. CONCLUSION: We advise that all blunt thoracic trauma patients should be screened for cardiac contusion by continuous ECG monitoring and troponin levels. @ 2022 Turkish Association of Trauma and Emergency Surgery.EnglishAll Open Access; Green Open AccessAttentionContusionsHumansLung InjuryMyocardial ContusionsRetrospective StudiesThoracic InjuriesTroponin IWounds, Nonpenetratingtroponin Itroponin IadultagedangiographyArticlecardiogenic shockcomorbiditycomputer assisted tomographycoronary artery obstructionechocardiographyelectrocardiographyfemalefollow upheart arrestheart arrhythmiaheart contusionheart ejection fractionhematopneumothoraxhematothoraxhumanhypotensionlung contusionmajor clinical studymalepericardial effusionpericardiocentesispneumothoraxretrospective studyrib fractureST segment elevationsternum fracturesupraventricular tachycardiatachycardiathorax injurytraffic accidentvery elderlyattentionblunt traumacontusiondiagnostic imagingheart contusionlung injurythorax injuryArticle10.14744/tjtes.2021.11290
