Prognostic Value of Troponin I with Echocardiography Assessment in Septic Patients

Abstract

Abstract Background Sepsis is heterogenous with regard to factors such as causal microorganism, patient predisposition, co-morbidity and response to therapy, a key element and unifying feature is the manifestation of cardiovascular dysfunction. Elevated concentrations of cardiac troponin I (cTnI) are frequently observed in patients with severe sepsis and septic shock even in the absence of an acute coronary syndrome (ACS). Objective To evaluate the prognostic value of (cTnI) with echocardiography assessment in septic patients. Patients and Methods This study was conducted at the intensive care units of Ain Shams university hospitals. 20 patients of both sexes with age ranging from 18 to 70 years diagnosed with sepsis admitted to Intensive care unit were included in prospective observational study. Results Baseline cTnI had a significant positive correlation with follow up troponine (p = 0.0016). Baseline EF had a significant negative correlation with follow up troponine (p = 0.036). Using ROC-curve analysis, troponin level at a cutoff point (>1.9) predicted patients with mortality, with good (87%) accuracy, sensitivity= 90% and specificity= 90% (p < 0.01). Conclusion Elevated concentrations of cardiac troponin I (cTnI) are frequently observed in patients with sepsis and septic shock even in the absence of an acute coronary syndrome.
