Abstract
Introduction: Myocardial contusion describes a condition of bruising or microscopically small hemorrhage of the heart muscle caused by blunt thoracic trauma. In patients who have sustained blunt thoracic trauma, the prevalence of myocardial contusion ranges from 0 to 76%, depending on the diagnostic criteria used (Leite et al., 2017). The severity of myocardial contusion can vary depending on the severity of the injury and when the injury occurs. It can be a life-threatening condition in patients who sustained blunt thoracic trauma. The diagnostic approach remains a subject of debate. It was demonstrated that, suspected myocardial contusion patients who have normal electrocardiograms (ECGs) and biomarker tests can be safely discharged. The Aim of this study: The aim is to detect the early development of myocardial contusion and its short term outcomes in patients with blunt chest trauma. Materials and methods: This is a cross sectional descriptive and analytical study The current study was conducted for 1 year duration starting from May 2021 to May 2022 in Mansoura University Emergency Hospital Mansoura, Egypt.The current study included 153 patients with isolated blunt chest trauma who were selected according to the specific criteria. Results: The study initially included 188 patients assessed for eligibility of enrolment. from this number, 35 cases were excluded due to different causes, so the final number included and analyzed was 153 cases.The mean heart rate was statistically significant higher in the cases with myocardial contusions as compared with the cases with no myocardial contusions. The global circumferential strains (GCS) and the mean arterial pressure (MAP) were statistically significant lower in the cases with myocardial contusions as compared with the cases with no myocardial contusions. The length of hospital stay and length of intensive care unit (ICU) stay were statistically significant longer in the cases with myocardial contusions. Conclusion: Blunt chest trauma (BCT) can cause a wide range of clinical presentations and injuries, making the diagnostics extremely challenging. Patients may initially appear hemodynamically stable and asymptomatic on admission. Keywords: Myocardial Contusion, Blunt Chest Trauma, Electrocardiograms, ICU.
