Prognostic value of chest radiographs in patients with acute heart failure: the Radiology in Acute Heart Failure (RAD-ICA) study. / Estudio RAD-ICA: valor pronóstico de la radiografía de tórax obtenida en urgencias en pacientes con insuficiencia cardiaca aguda.

OBJECTIVES: To determine whether chest radiographs can contribute to prognosis in patients with acute heart failure (AHF). MATERIAL AND METHODS: Consecutive patients with AHF were enrolled by the participating emergency departments. Radiographic variables assessed were the presence or absence of evidence of cardiomegaly and pleural effusion and the pulmonary parenchymal pattern observed (vascular redistribution, interstitial edema, and/or alveolar edema). We gathered variables for the AHF episode and the patient's baseline state. Outcomes were in-hospital and 1-year mortality; hospital stay longer than 7 days, and a composite of events within 30 days of discharge (revisit, rehospitalization, and/or death). Crude and adjusted hazard ratios were calculated for the 3 categories of radiographic variables. The variables were also studied in combination. RESULTS: A total of 2703 patients with a mean (SD) age of 81 (19) years were enrolled; 54.5% were women. Cardiomegaly was observed in 1711 cases (76.8%) and pleural effusion in 992 (36.7%). A pulmonary parenchymal pattern was observed in all cases, as follows: vascular redistribution in 1672 (61.9%), interstitial edema in 629 (23.3%) and alveolar edema in 402 (14.9%). The adjusted hazard ratios showed that cardiomegaly lacked prognostic value. However, the presence of pleural effusion was associated with a 23% (95% CI, 2%-49%) higher rate of the 30- day composite outcome; in-hospital mortality was 89% (30%-177%) higher in the presence of alveolar edema, and 1-year mortality was 38% (14%-67%) higher in association with vascular redistribution. The results for the variables in combination were consistent with the results for individual variables. CONCLUSION: A diagnostic chest radiograph can also contribute to the prediction of adverse events. Pleural effusion is associated with a higher rate of events after discharge, and alveolar edema is associated with higher mortality.

OBJETIVO: Investigar si la radiografía de tórax en pacientes con insuficiencia cardiaca aguda (ICA) puede contribuir a establecer el pronóstico. METODO: Se incluyeron pacientes consecutivos diagnosticados de ICA en urgencias. Se valoró: cardiomegalia radiológica (CR), derrame pleural (DP) y el patrón parenquimatoso pulmonar (PPP: redistribución vascular, edema intersticial, edema alveolar). Se recogieron variables del estado basal del paciente y del episodio. Las variables de resultado evaluadas fueron mortalidad intrahospitalaria y al año, ingreso prolongado (> 7 días) y evento combinado (reconsulta, rehospitalización o muerte) a 30 días postalta, para las cuales se calcularon las hazard ratio crudas y ajustadas para las tres variables radiológicas y su combinación entre ellas. RESULTADOS: Se incluyeron 2.703 pacientes con una edad media de 81 (DE 19) años; el 54,5% eran mujeres. Se observó CR en 1.711 casos (76,8%), DP en 992 (36,7%) y todos los pacientes mostraron PPP (redistribución vascular el 61,9%, edema intersticial el 23,3% y edema alveolar el 14,9%). El análisis ajustado mostró que la CR no tuvo valor pronóstico; el DP incrementó un 23% (IC 95% 2-49%) los eventos combinados a los 30 días postalta; y el PPP edema alveolar aumentó un 89% (30-177%) la mortalidad intrahospitalaria y un 38% (14-67%) la mortalidad al año respecto al PPP redistribución vascular (referencia). El estudio de la combinación de estos tres hallazgos radiológicos mostró resultados similares y congruentes con los hallazgos del estudio individualizado. CONCLUSIONES: La radiografía de tórax, además de ayudar a establecer el diagnóstico de ICA, puede contribuir a estimar el pronóstico de eventos adversos. Así, el DP se asocia a un incremento de eventos adversos postalta y el PPP edema alveolar a una mayor mortalidad.

Comparative Analysis of Short-Term Outcomes of Patients With Heart Failure With a Mid-Range Ejection Fraction After Acute Decompensation.

To determine short-term outcomes after an episode of acute heart failure in patients with mid-range ejection fraction (40%-49%; HFmrEF) compared with patients with reduced (<40%) and preserved (>49%) ejection fractions (HFrEF and HFpEF, respectively) and according to their final destination after emergency department (ED) care. This is an exploratory, secondary analysis of the Epidemiology of Acute Heart Failure in the Emergency departments Registry, which includes consecutive acute heart failure patients diagnosed in 41 Spanish EDs. Patients with echocardiography data were included and divided into HFrEF, HFmrEF, and HFpEF. The primary outcome was 30-day all-cause mortality, and secondary outcomes were in-hospital all-cause mortality, hospital length of stay >10 days, and 30-day postdischarge ED revisit due to AHF and combined end point (ED revisit and/or death). We included 6,856 patients (age 79 [10]; 52.1% women): 21.6% had HFrEF, 14.3% HFmrEF, and 64.1% HFpEF. The main destinations for the 982 HFmrEF patients after ED management were internal medicine (293, 29.8%), cardiology (194, 19.9%) and not hospitalized (241, 24.5%), whereas the remaining 254 patients were admitted to other departments, including geriatric wards, short-stay units and intensive care units. Outcomes for HFmrEF did not differ compared with either HFrEF or HFpEF. Compared with HFmrEF admitted to cardiology, internal medicine admission or direct ED discharge increased the 30-day postdischarge ED revisit (hazard ratio [HR] 1.713, 95% confidence interval [CI] 1.042 to 2.816; and HR 1.683, 95% CI 1.046 to 2.708, respectively) and the 30-day postdischarge combined end point (HR 1.732, 95% CI 1.070 to 2.803; and HR 1.727, 95% CI 1.083 to 2.756, respectively). In conclusion, patients in the newly created HFmrEF category suffering from an acute decompensation have similar short-term outcomes as those in the classical HFrEF and HFpEF categories; nonetheless, HFmrEF patients handled in cardiology wards during decompensation obtain better outcomes, and reasons for these differences have to be unmasked and corrected.

Clinical phenotypes of acute heart failure based on signs and symptoms of perfusion and congestion at emergency department presentation and their relationship with patient management and outcomes.

OBJECTIVE: To compare the clinical characteristics and outcomes of patients with acute heart failure (AHF) according to clinical profiles based on congestion and perfusion determined in the emergency department (ED). METHODS AND RESULTS: Overall, 11 261 unselected AHF patients from 41 Spanish EDs were classified according to perfusion (normoperfusion = warm; hypoperfusion = cold) and congestion (not = dry; yes = wet). Baseline and decompensation characteristics were recorded as were the main wards to which patients were admitted. The primary outcome was 1-year all-cause mortality; secondary outcomes were need for hospitalisation during the index AHF event, in-hospital all-cause mortality, prolonged hospitalisation, 7-day post-discharge ED revisit for AHF and 30-day post-discharge rehospitalisation for AHF. A total of 8558 patients (76.0%) were warm + wet, 1929 (17.1%) cold + wet, 675 (6.0%) warm + dry, and 99 (0.9%) cold + dry; hypoperfused (cold) patients were more frequently admitted to intensive care units and geriatrics departments, and warm + wet patients were discharged home without admission. The four phenotypes differed in most of the baseline and decompensation characteristics. The 1-year mortality was 30.8%, and compared to warm + dry, the adjusted hazard ratios were significantly increased for cold + wet (1.660; 95% confidence interval 1.400-1.968) and cold + dry (1.672; 95% confidence interval 1.189-2.351). Hypoperfused (cold) phenotypes also showed higher rates of index episode hospitalisation and in-hospital mortality, while congestive (wet) phenotypes had a higher risk of prolonged hospitalisation but decreased risk of rehospitalisation. No differences were observed among phenotypes in ED revisit risk. CONCLUSIONS: Bedside clinical evaluation of congestion and perfusion of AHF patients upon ED arrival and classification according to phenotypic profiles proposed by the latest European Society of Cardiology guidelines provide useful complementary information and help to rapidly predict patient outcomes shortly after ED patient arrival.

Influence of the length of hospitalisation in post-discharge outcomes in patients with acute heart failure: Results of the LOHRCA study.

OBJECTIVE: To investigate the relationship between length of hospitalisation (LOH) and post-discharge outcomes in acute heart failure (AHF) patients and to ascertain whether there are different patterns according to department of initial hospitalisation. METHODS: Consecutive AHF patients hospitalised in 41 Spanish centres were grouped based on the LOH (<6/6-10/11-15/>15 days). Outcomes were defined as 90-day post-discharge all-cause mortality, AHF readmissions, and the combination of both. Hazard ratios (HRs), adjusted by chronic conditions and severity of decompensation, were calculated for groups with LOH >6 days vs. LOH <6 days (reference), and stratified by hospitalisation in cardiology, internal medicine, geriatrics, or short-stay units. RESULTS: We included 8563 patients (mean age: 80 (SD = 10) years, 55.5% women), with a median LOH of 7 days (IQR 4-11): 2934 (34.3%) had a LOH <6 days, 3184 (37.2%) 6-10 days, 1287 (15.0%) 11-15 days, and 1158 (13.5%) >15 days. The 90-day post-discharge mortality was 11.4%, readmission 32.2%, and combined endpoint 37.4%. Mortality was increased by 36.5% (95%CI = 13.0-64.9) when LOH was 11-15 days, and by 72.0% (95%CI = 42.6-107.5) when >15 days. Conversely, no differences were found in readmission risk, and the combined endpoint only increased 21.6% (95%CI = 8.4-36.4) for LOH >15 days. Stratified analysis by hospitalisation departments rendered similar post-discharge outcomes, with all exhibiting increased mortality for LOH >15 days and no significant increments in readmission risk. CONCLUSIONS: Short hospitalisations are not associated with worse outcomes. While post-discharge readmissions are not affected by LOH, mortality risk increases as the LOH lengthens. These findings were similar across hospitalisation departments.

Effect of risk of malnutrition on 30-day mortality among older patients with acute heart failure in Emergency Departments.

BACKGROUND: Little is known about the prevalence and impact of risk of malnutrition on short-term mortality among seniors presenting with acute heart failure (AHF) in emergency setting. The objective was to determine the impact of risk of malnutrition on 30-day mortality risk among older patients who attended in Emergency Departments (EDs) for AHF. MATERIAL AND METHODS: We performed a secondary analysis of the OAK-3 Registry including all consecutive patients ≥65 years attending in 16 Spanish EDs for AHF. Risk of malnutrition was defined by the Mini Nutritional Assessment Short Form (MNA-SF) < 12 points. Unadjusted and adjusted logistic regression models were used to assess the association between risk of malnutrition and 30-day mortality. RESULTS: We included 749 patients (mean age: 85 (SD 6); 55.8% females). Risk of malnutrition was observed in 594 (79.3%) patients. The rate of 30-day mortality was 8.8%. After adjusting for MEESSI-AHF risk score clinical categories (model 1) and after adding all variables showing a significantly different distribution among groups (model 2), the risk of malnutrition was an independent factor associated with 30-day mortality (adjusted OR by model 1 = 3.4; 95%CI 1.2-9.7; p = .020 and adjusted OR by model 2 = 3.1; 95%CI 1.1-9.0; p = .033) compared to normal nutritional status. CONCLUSIONS: The risk of malnutrition assessed by the MNA-SF is associated with 30-day mortality in older patients with AHF who were attended in EDs. Routine screening of risk of malnutrition may help emergency physicians in decision-making and establishing a care plan.

Mortality after an episode of acute heart failure in a cohort of patients with intermediate ventricular function: Global analysis and relationship with admission department. / Mortalidad tras un episodio de insuficiencia cardiaca aguda en una cohorte de pacientes con función ventricular intermedia: análisis global y en relación con el lugar de ingreso.

BACKGROUND AND OBJECTIVE: To compare the outcome of patients with acute heart failure (AHF) with a mid-range left ventricular ejection fraction (HFmrEF) with patients with a reduced (HFrEF) or preserved (HFpEF) left ventricular ejection fraction. PATIENTS AND METHOD: A prospective observational study included patients diagnosed with AHF in 41 emergency departments. Patients were divided into 3 groups: HFrEF<40%, HFmrEF 40-49% and HFpEF≥50%. We collected 38 independent variables and the adjusted and crude all-cause mortality at one-year in the HFmrEF group was compared with that of the HFrEF and HFpEF groups. The analysis was stratified according to patient destination following ED care. RESULTS: Three thousand nine hundred and fifty-eight patients were included: 580 HFmrEF (14.6%), 929 HFrEF (23.5%) and 2,449 HFpEF (61.9%). Global mortality at one year was 28.5%. The crude mortality of the HFmrEF group was similar to that of the HFpEF group (HR 1.009; 95% CI 0.819-1.243; P=.933) and lower than the HFrEF group (HR 0.800; 95% CI 0.635-1.008; P=.058), but after adjustment for discordant basal characteristics among groups, the mortality of the HFmrEF group did not differ from that of the HFpEF (HRa 1.025; 95% CI 0.825-1.275; P=.821) or HFrEF group (HRa 0.924; 95% CI 0.720-1.186; P=.535). Neither were significant differences found between the HFmrEF group and the other 2 groups in the analysis stratified according to admission or discharge direct from the emergency department. CONCLUSION: Mortality at one-year after an AHF episode in patients with HFmrEF does not differ from that of patients with HFpEF or HfrEF, either globally or based on the main destinations after emergency department care.

Time trends in characteristics, clinical course, and outcomes of 13,791 patients with acute heart failure.

OBJECTIVES: To analyse time trends in patient characteristics, clinical course, hospitalisation rate, and outcomes in acute heart failure along a 10-year period (2007-2016). METHODS: The EAHFE registry has prospectively collected 13,971 consecutive AHF patients diagnosed in 41 Spanish emergency departments (EDs) at five different time points (2007/2009/2011/2014/2016). Eighty patient-related variables and outcomes were described and statistically significant changes along time were evaluated. We also compared our data with large ED- and hospital-based registries. RESULTS: Compared to other large registries, our patients were older [80 (10) years], more frequently women (55.5%), and had a higher prevalence of hypertension (83.5%) and a lower prevalence of ischaemic cardiomyopathy (29.4%). De novo AHF was observed in 39.6%. 63.6% showed some degree of functional dependence and 56.1% had preserved left ventricular ejection fraction (LVEF). 56.8% of the patients arrived at the ED by ambulance, 4.5% arrived hypotensive, and 21.3% hypertensive. Direct discharge from the ED home was seen in 24.9%, and internal medicine (32.5%) and cardiology (15.8%) were the main hospital destinations. Triggers for decompensation were identified in 75.4%, the most being frequent infection (35.2%) and rapid atrial fibrillation (14.7%). The AHF phenotypes were: warm/wet 82.0%, warm/dry 6.2%, cold/wet 11.1%, and cold/dry 0.7%. The length of hospitalisation was 9.3 (8.6) days, and in-hospital, 30-day, and 1-year all-cause mortality were 7.8, 10.2 and 30.3%, respectively; and 30-day re-hospitalisation and ED revisit due to AHF were 16.9 and 24.8%, respectively. Thirty-nine of the eighty characteristics studied showed significant changes over time, while all outcomes remained unchanged along the 10-year period. CONCLUSIONS: The EAHFE Registry is the first European ED-based registry describing the characteristics, clinical course, and outcomes of a cohort resembling the universe of patients with AHF. Significant changes were observed over time in some aspects of AHF characteristics and management, but not in outcomes.

Insuficiencia cardíaca con fracción de eyección intermedia: ¿Nueva entidad? / Heart failure with mid-range left ventricular ejection fraction: New entity?

En la actualidad se describe una nueva clasificación de pacientes con insuficiencia cardíaca (IC) según la fracción de eyección del ventrículo izquierdo (FEVI), la IC con FEVI intermedia (ICFEi) entre 40 y 49%. Esta se incluye en la anterior clasificación de IC con FEVI mayor del 50% o FEVI preservada (ICFEp) y la IC con FEVI reducida (ICFEr), menor del 40 %. Este nuevo grupo de pacientes representa entre el 16-20% de los pacientes con IC, por lo que desde su publicación han habido varios estudios interesados en descubrir las características de estos. Tras revisar los estudios de los que disponemos actualmente se pueden extraer algunas conclusiones respecto a los que presentan ICFEi, que comparten características clínicas, epidemiológicas y etiológicas con los otros dos patrones (ICFEp e ICFEr); por lo que cabe la posibilidad de que la ICFEi represente más un estado transicional entre ICFEr y ICFEp que una entidad independiente en sí misma. Los pacientes con ICFEi no presentan diferencias en la mortalidad frente a los otros 2 grupos, excepto en aquellos con cardiopatía isquemia en los cuales la mortalidad es similar a la de pacientes con ICFEr. Se recomienda tratar a los que tienen ICFEi de forma similar a aquellos con ICFEp, aunque se ha observado que los primeros se benefician de un tratamiento similar a los que padecen ICFEr

Currently, a new classification of patients with heart failure (HF) according to the left ventricular ejection fraction (LVEF), the HF with mid-range LVEF (HFmrEF) between 40 and 49% is described. This is included in the previous classification of HF with LVEF greater than 50% or preserved LVEF (HFpEF) and HF with reduced LVEF (HFrEF), less than 40%. This new group of patients represents between 16-20% of patients with HF, thus, since its publication, there have been several studies interested in discovering the characteristics of these. After reviewing the studies that we currently have, we can draw some conclusions regarding those with HFmrEF, which share clinical, epidemiological and etiological characteristics with the other two patterns (HFpEF and HFrEF); therefore, it is possible that the HFmrEF represents more a transitional state between HFrEF and HFpEF than an independent entity in itself. Patients with HFpEF do not show differences in mortality compared to the other two groups, except in those with ischemic heart disease in whom mortality is similar to that in patients with HFrEF. It is recommended to treat those who have HFmrEF in a similar way to those with HFpEF, although it has been observed that the former benefit from a treatment similar to those with HFrEF
