Markedly elevated high-sensitivity troponin I in severe polytrauma without acute coronary syndrome: case report

Öz

Interpreting markedly elevated cardiac biomarkers in severe polytrauma presents a recurrent diagnostic dilemma, requiring the differentiation of acute coronary syndrome from trauma-related injury and rhabdomyolysis. A 54-year-old woman with no known comorbidities was admitted to the emergency department following an accidental fall from approximately 5 meters. Initial evaluation revealed hypotension requiring fluid resuscitation. Contrast-enhanced computed tomography demonstrated multiple injuries, including right-sided pneumothorax, rib fractures, pelvic fractures classified as Young-Burgess lateral compression type I, and a grade II renal laceration. The electrocardiogram showed no signs of acute ischemia at any time point. High-sensitivity troponin I peaked at 1097.8 nanograms per liter (approximately 27 times the upper reference limit), while creatine kinase and creatine kinase-MB continued to rise, a pattern incompatible with acute myocardial infarction and consistent with concomitant rhabdomyolysis. Transthoracic echocardiography was normal. Acute coronary syndrome was excluded by cardiology evaluation, and invasive coronary investigation was not pursued. This case highlights the importance of integrating clinical context, electrocardiographic findings, echocardiography, and biomarker kinetics when interpreting markedly elevated cardiac biomarkers in polytrauma patients.
