BackgroundSepsis is a high mortality condition characterized by multi-organ dysfunction. Sepsis-induced cardiomyopathy (SIC) refers to cardiac dysfunction in sepsis.ObjectivesOur goal was to determine whether SIC can be detected in the emergency department (ED) using focused cardiac ultrasound (FCU).MethodsA retrospective analysis of adults presenting to a single ED with sepsis over a 21-month period was performed. Patients were included if they met clinical sepsis criteria, received an FCU by an emergency physician in the ED, and a baseline echocardiogram performed in the previous 12 months. SIC was defined as a significant decrease in estimated left ventricular ejection fraction (LVEF) by FCU relative to baseline. Demographic and outcome characteristics were compared between three cohorts: patients with normal baseline LVEF and no decrease on presentation, patients with decreased LVEF and no significant change, and those with a significant decrease in LVEF from their normal baseline (SIC).ResultsThere were 110 patients that met inclusion criteria: 89 patients (81%) in the normal LVEF group, 12 (11%) in the prior decreased LVEF group, and 9 (8%) in the SIC group. Unadjusted mortality at 90 days for patients with SIC (67%) and prior decreased LVEF (58%) was significantly higher than those with normal EF (29%) (p = 0.019). When adjusted for age, gender, Charlson Index score, and lactate > 4.0 mmol/L, SIC was associated with mortality at 90 days (odds ratio 6.1, 95% confidence interval 1.37-32.92).ConclusionSIC can be detected using FCU by emergency physicians in the ED and is associated with increased 90-day mortality.Copyright © 2022 Elsevier Inc.
