Abstract
INTRODUCTION. Although cardiac injury was reported in patients with neurosurgical conditions, few data reported cardiac injury in patients with traumatic brain injury (TBI). OBJECTIVES. The aim of this work is to report the incidence of cardiac injury in patients with TBI and its impact on patient outcome. METHODS. A prospective observational study was conducted on a cohort of 50 patients with severe TBI. Only Patients with isolated severe TBI defined as Glascow coma scale (GCS) < 8 were included in the study. APACHE II score, GCS, hemodynamic data, serum Troponin I, electrocardiogram (ECG), echocardiographic examination, and patients’ outcome were recorded. A Cardiac Injury Score (CIS) was calculated for all patients (elevated troponin = 1, abnormal echocardiography defined as ejection fraction <55% and/or regional wall motion abnormalities = 1, hypotension = 1), univariate and multivariate analysis for risk factors for mortality was done for all risk factors
