Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).

Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.

Article Synopsis
  • The study aimed to investigate the relationship between air pollutants and the severity of decompensated heart failure in patients attending emergency departments in Spain.
  • A total of 5,292 patients, primarily elderly and mostly women, were analyzed, with data collected on pollutants like SO, NO, and CO, among others.
  • The results indicated that only sulfur dioxide (SO) showed a linear correlation with the severity of heart failure, particularly in increasing the likelihood of hospitalization, while other pollutants did not demonstrate clear associations.

Background And Importance: A higher incidence of venous thromboembolism [both pulmonary embolism and deep vein thrombosis (DVT)] in patients with coronavirus disease 2019 (COVID-19) has been described. But little is known about the true frequency of DVT in patients who attend emergency department (ED) and are diagnosed with COVID-19.

Objective: We investigated the incidence, risk factors, clinical characteristics and outcomes of DVT in patients with COVID-19 attending the ED before hospitalization.

Objective: Experts recommended that direct discharge without hospitalization (DDWH) for emergency departments (EDs) able to observe acute heart failure (AHF) patients should be >40%, and these discharged patients should fulfil the following outcome standards: 30-day all-cause mortality <2% (outcome A); 7-day ED revisit due to AHF < 10% (outcome B); and 30-day ED revisit/hospitalization due to AHF < 20% (outcome C). We investigated these outcomes in a nationwide cohort and their relationship with the ED DDWH percentage.

Methods: We analyzed the EAHFE registry (includes about 15% of Spanish EDs), calculated DDWH percentage of each ED, and A/B/C outcomes of DDWH patients, overall and in each individual ED.

Objectives: This study investigated whether systemic corticosteroids (new onset) administered to patients with acute heart failure (AHF) have any association with outcomes, with differentiated analyses for patients with and without chronic obstructive pulmonary disease (COPD) as a comorbidity.

Background: Patients with undiagnosed dyspnea frequently receive corticosteroids in emergency departments while determining a final diagnosis, but their effect on the outcomes of patients with AHF without overt COPD exacerbation is unknown.

Methods: We selected patients with AHF from the EAHFE (Epidemiology of Acute Heart Failure in the Emergency Departments) registry, recording key data (new-onset corticosteroid therapy, COPD condition).

Article Synopsis
  • The study focused on how the length of hospitalisation (LOH) affects the outcomes of patients with acute heart failure (AHF) after they are discharged, comparing results across different hospital departments.
  • Out of 8,563 patients analyzed, 90-day outcomes showed that longer hospital stays led to higher post-discharge mortality rates, particularly for those staying over 15 days, but readmission rates remained constant regardless of LOH.
  • The research concluded that shorter hospital stays do not lead to worse outcomes, and higher mortality risks associated with longer stays were consistent across various hospital departments.

Article Synopsis
  • The study investigates how the risk of malnutrition affects 30-day mortality rates in elderly patients experiencing acute heart failure (AHF) in emergency departments.
  • It analyzed data from 749 patients aged 65 and older, finding that 79.3% were at risk of malnutrition and the overall 30-day mortality rate was 8.8%.
  • The results indicate that malnutrition is a significant independent factor for higher 30-day mortality, suggesting that routine screening for malnutrition could improve patient care and management in emergency settings.

Article Synopsis
  • - The EAHFE-TROPICA3 study focused on patients with acute heart failure (AHF) who did not have cardiac troponin (cTn) levels measured, aiming to uncover their characteristics and compare them to those who did have cTn determined.
  • - Among 8,850 AHF patients, nearly half (47.6%) did not undergo cTn testing; these patients had fewer instances of ischemic heart disease and often took more diuretics, but used fewer heart medications like ACE inhibitors and beta-blockers.
  • - Despite differing clinical profiles, patients with and without cTn testing experienced similar rates of in-hospital mortality and follow-up complications, suggesting that lack of cT

The TRAPID-AMI (High Sensitivity Cardiac Troponin T assay for rapid Rule-out of Acute Myocardial Infarction) study evaluated a rapid "rule-out" acute myocardial infarction (AMI). We evaluated what symptoms were associated with AMI as part of a substudy of TRAPID-AMI. There were 1282 patients evaluated from 12 centers in Europe, the United States of America, and Australia from 2011 to 2013.

Aims: Heart failure (HF) is prevalent in older adults and is associated with impaired physical and cognitive function. However, these factors are rarely included in studies about long-term prognosis of HF. The aim of the study was to determine whether functional status and delirium at admission (prevalent delirium) would predict 1-year mortality in patients with decompensated HF (DHF).

Aims: To compare short-term outcomes after an episode of acute heart failure (AHF) in patients with reduced and preserved ejection fractions (HFrEF, < 40%; and HFpEF, > 49%; respectively) according to their destinations after emergency department (ED) care.

Methods And Results: This secondary analysis of the EAHFE Registry (consecutive AHF patients diagnosed in 41 Spanish EDs) investigated 30-day all-cause mortality, in-hospital all-cause mortality, prolonged hospitalisation (> 7 days), and 30-day post-discharge ED revisit due to AHF, all-cause death, and combined endpoint (ED revisit/death) in 5829 patients with echocardiographically documented HFrEF and HfpEF (HFrEF/HFpEF: 1,442/4,387). Adjusted ratios were calculated for patients admitted to internal medicine (IM), short stay unit (SSU), and discharged from the ED without hospitalisation (DEDWH) and compared with those admitted to cardiology.

Background: The 1-hour (h) algorithm triages patients presenting with suspected acute myocardial infarction (AMI) to the emergency department (ED) towards "rule-out," "rule-in," or "observation," depending on baseline and 1-h levels of high-sensitivity cardiac troponin (hs-cTn). The economic consequences of applying the accelerated 1-h algorithm are unknown.

Methods And Findings: We performed a post-hoc economic analysis in a large, diagnostic, multicenter study of hs-cTnT using central adjudication of the final diagnosis by two independent cardiologists.

The objectives were to determine the impact of frailty and disability on 30-day mortality and whether the addition of these variables to HFRSS EFFECT risk score (FBI-EFFECT model) improves the short-term mortality predictive capacity of both HFRSS EFFECT and BI-EFFECT models in older patients with acute decompensated heart failure (ADHF) atended in the emergency department. We performed a retrospective analysis of OAK Registry including all consecutive patients ≥65 years old with ADHF attended in 3 Spanish emergency departments over 4 months. FBI-EFFECT model was developed by adjusting probabilities of HFRSS EFFECT risk categories according to the 6 groups (G1: non frail, no or mildly dependent; G2: frail, no or mildly dependent; G3: non frail, moderately dependent; G4: frail, moderately dependent; G5: severely dependent; G6: very severely dependent).
