biostudies-literatureUnknown13(7)Keefer SIntroduction Patients that present to the emergency department (ED) with undifferentiated hypotension have a high mortality rate. Hypotension can be divided into four categories: obstructive, hypovolemic, distributive, and cardiogenic. While it is possible to have overlapping or concomitant shock states, being able to differentiate between cardiogenic shock and the other categories is important as it entails a different treatment regime and extra cautions. In this secondary analysis, we investigate if using focused cardiac ultrasonography (FOCUS) to determine left ventricular dysfunction (LVD) can serve as a reliable test for cardiogenic shock. Methods We prospectively collected FOCUS findings performed in 135 ED patients with undifferentiated hypotension as part of an international study.Cureuse16360https://www.ebi.ac.uk/biostudies/studies/S-EPMC8360322biostudies-literatureSonographic Findings of Left Ventricular Dysfunction to Predict Shock Type in Undifferentiated Hypotensive Patients: An Analysis From the Sonography in Hypotension and Cardiac Arrest in the Emergency Department (SHoC-ED) Study.PMC8360322Milne JChandra KKeefer SStander MLussier DOlszynski PADiegelmann LPham CPeach MLamprecht HAtkinson PFraser JHenneberry RJLewis DfalseSonographic Findings of Left Ventricular Dysfunction to Predict Shock Type in Undifferentiated Hypotensive Patients: An Analysis From the Sonography in Hypotension and Cardiac Arrest in the Emergency Department (SHoC-ED) Study.Introduction Patients that present to the emergency department (ED) with undifferentiated hypotension have a high mortality rate.
