The prognostic value of left ventricular function on sepsis outcomes in critical care unit patients

ABSTRACT

Background: Sepsis is the most prevalent life menacing condition presupposed patients' admission to intensive care units. The underlying cardiovascular consequences of sepsis comprehended marvelous increase of the cardiac output, reduction of the peripheral vascular resistance along with impaired capillary permeability.Aim of the study The present investigation was implemented to retrieve the prognostic value of LVF assessment using speckle tracking echocardiography (STE) among Egyptian adults, who admitted to the intensive care unit as a resultant impact of sepsis or septic shock.Methods: Patients admitted at the Critical Care Unit, who initially diagnosed with sepsis or septic shock within 8 hours. After fulfilling their criteria and being aged more than 18 years, they were eligible for inclusion in the study. All participants were submitted to rigorous history taking, clinical evaluation, laboratory assessment, and STE. The study embraced an overall 50 patients.Results: Left ventricular longitudinal strain (LVGLS) was the only parameter which attained statistically significant highly positive correlation with SOFA score among septic shock patients (r = 0.794, p = 0.021). The results of this model revealed that LVGLS (p<0.001) attained high ability in the prediction of Sepsis-related Organ Failure Assessment (SOFA) score and Acute Physiologic and Chronic Health Evaluation (APACHE) score.Conclusions: The capability of STE investigation for the detection of left ventricular dysfunction among septic or septic shocked critically ill patients is a promising and feasible approach, which have a crucial impact on the prognosis of such patients
