Chouihed T, et al. - This retrospective trial evaluated the prognostic value of hyponatraemia, hyperglycaemia and impaired estimated glomerular filtration rate (eGFR) in predicting in-hospital death in subjects with acute heart failure (AHF) admitted for acute dyspnoea in the Emergency Department. The yielded data of basic routine laboratory tests (hyponatraemia, hyperglycaemia and impaired eGFR) performed on admission in the Emergency Department appeared to be independently related to the in-hospital death. The early detection of patients admitted for AHF who were at high risk of in-hospital death could be facilitated via these inexpensive tests, performed as early as the patient admission in the Emergency Department.
