Prognosis of acute heart failure in patients followed up in nursing homes in Spain: Results from the RICA registry / Impacto pronóstico en la supervivencia de los pacientes en residencias de ancianos con insuficiencia cardiaca en España: Resultados del Registro RICA

Background: Patients with chronic diseases such as heart failure (HF) are at risk of hospital admission. We evaluated the impact of living in nursing homes (NH) on readmissions and all-cause mortality of HF patients during a one-year follow up. Methods: An observational and multicenter study from the Spanish National Registry of Heart Failure (RICA) was performed. We compared clinical and prognostic characteristics between both groups. Bivariate analyses were performed using Student's t-test and Tukey's method and a Kaplan–Meier survival at one-year follow up. A multivariate proportional hazards analysis of [Cox] regression by the conditional backward method was conducted for the variables being statistically significant related to the probability of death in the univariate. Results: There were 5644 patients included, 462 (8.2%) of whom were nursing home residents. There were 52.7% women and mean age was 79.7±8.8 years. NH residents had lower Barthel (74.07), Charlson (3.27), and Pfeiffer index (2.2), p<0.001). Mean pro-BNP was 6686pg/ml without statistical significance differences between groups. After 1-year follow-up, crude analysis showed no differences in readmissions 74.7% vs. 72.3%, p=0.292, or mortality 63.9% vs. 61.1%, p=0.239 between groups. However, after controlling for confounding variables, NH residents had a higher 1-year all-cause mortality (HR 1.153; 95% CI 1.011–1.317; p=0.034). Kaplan–Meier analysis showed worse survival in nursing home residents (log-rank of 7.12, p=0.008). Conclusions: Nursing home residents with heart failure showed higher one-year mortality which could be due to worse functional status, higher comorbidity, and cognitive deterioration.(AU)

Introducción: Los pacientes con enfermedades crónicas como la insuficiencia cardiaca (IC) presentan mayor riesgo de ingreso. Se evaluó el impacto sobre los reingresos y la mortalidad por todas las causas de los pacientes con IC respecto a vivir o no en residencias de ancianos durante un año de seguimiento. Métodos: Estudio observacional y multicéntrico a partir del Registro Nacional de Insuficiencia Cardiaca (RICA). Se compararon las características clínicas y pronósticas entre ambos grupos. Se realizó un análisis bivariante mediante el método de t de Student y Tukey y un análisis de supervivencia mediante Kaplan-Meier al año de seguimiento, así como un análisis multivariante de riesgos proporcionales de regresión (Cox) por el método de retroceso condicional para las variables que se relacionaban de forma estadísticamente significativa con la probabilidad de muerte en el univariante. Resultados: Fueron incluidos 5.644 pacientes; 462 (8,2%) de ellos estaban en residencias, el 52,7% eran mujeres y la edad media era de 79,7±8,8 años. Los pacientes en residencias tenían menor Barthel (74,07), Charlson (3,27) y Pfeiffer (2,2) (p<0,001). El pro-BNP medio era de 6.686 pg/ml sin diferencias significativas. Tras un año de seguimiento, el análisis bruto no mostró diferencias en los reingresos (74,7 vs. 72,3%; p=0,292) ni en mortalidad (63,9 vs. 61,1%; p=0,239) entre ambos grupos. Tras controlar las variables de confusión, los pacientes en residencias presentaron una mayor mortalidad por todas las causas a un año (hazard ratio 1,153; IC 95%: 1,011-1,317; p=0,034) así como peor supervivencia en el análisis de Kaplan-Meier (log-rank 7,12; p=0,008). Conclusiones: Los pacientes con IC en residencias de ancianos mostraron una mayor mortalidad a un año, que podría deberse a un peor estado funcional, a mayor deterioro cognitivo y a más comorbilidad.(AU)

The two different profiles in heart failure with preserved ejection fraction and type 2 diabetes mellitus: ischemic and diabetic.

OBJECTIVE: Two profiles of patients with heart failure with preserved ejection fraction (HFpEF) and type 2 diabetes mellitus (T2DM) can be discerned: those with ischemic and those with diabetic cardiomyopathy (DMC). We aim to analyze clinical differences and prognosis between patients of these two profiles. MATERIAL AND METHODS: This cohort study analyzes data from the Spanish Heart Failure Registry, a multicenter, prospective registry that enrolled patients admitted for decompensated heart failure and followed them for one year. Three groups were created according to the presence of T2DM and heart disease depending on the etiology (ischemic when coronary artery disease was present, or DMC when no coronary, valvular, or congenital heart disease; no hypertension; nor infiltrative cardiovascular disease observed on an endomyocardial biopsy). The groups and outcomes were compared. RESULTS: A total of 466 patients were analyzed. Group 1 (n = 210) included patients with ischemic etiology and T2DM. Group 2 (n = 112) included patients with DMC etiology and T2DM. Group 3 (n = 144), a control group, included patients with ischemic etiology and without T2DM. Group 1 had more hypertension and dyslipidemia; group 2 had more atrial fibrillation (AF) and higher body mass index; group 3 had more chronic kidney disease and were older. In the regression analysis, group 3 had a better prognosis than group 1 (reference group) for cardiovascular mortality and HF readmissions (HR 0.44;95%CI 0.2-1; p = .049). CONCLUSIONS: Patients with T2DM and HFpEF, who had the poorest prognosis, were of two different profiles: either ischemic or DMC etiology. The first had a higher burden of cardiovascular disease and inflammation whereas the second had a higher prevalence of obesity and AF. The first had a slightly poorer prognosis than the second, though this finding was not significant.

Prognosis of acute heart failure in patients followed up in nursing homes in Spain: Results from the RICA registry.

CONCLUSIONS: Nursing home residents with heart failure showed higher one-year mortality which could be due to worse functional status, higher comorbidity, and cognitive deterioration.

Prognostic Impact of the UMIPIC Program in the Follow Up in Patients with Heart Failure and Cardiorenal Syndrome.

BACKGROUND: Individuals suffering from heart failure (HF) and cardiorenal syndrome (CRS) represent a special group of patients considering their age, multiple health issues, and treatment challenges. These factors make them more susceptible to frequent hospital stays and a higher mortality rate. UMIPIC is a multidisciplinary care model program for patients with heart failure follow up provided by internists and nurses who are experts in this entity. Our study delved into the effectiveness of this specialized care program (UMIPIC) in mitigating these risks for HF and CRS patients. METHODS: We analyzed the medical records of 3255 patients diagnosed with HF and CRS types 2 and 4, sourced from the RICA registry. These patients were divided into two distinct groups: those enrolled in the UMIPIC program (1205 patients) and those under standard care (2050 patients). Using propensity score matching, we ensured that both groups were comparable. The study focused on tracking hospital admissions and mortality rates for one year after an HF-related hospital stay. RESULTS: Patients in the UMIPIC group experienced fewer hospital readmissions due to HF compared to their counterparts (20% vs. 32%; Hazard Ratio [HR] = 0.48; 95% Confidence Interval [95% CI]: 0.40-0.57; p < 0.001). They also showed a lower mortality rate (24% vs. 36%; HR = 0.64; 95% CI: 0.54-0.75; p < 0.001). Furthermore, the UMIPIC group had fewer total hospital admissions (36% vs. 47%; HR = 0.58; 95% CI: 0.51-0.66; p < 0.001). CONCLUSIONS: The UMIPIC program, centered on holistic and ongoing care, effectively reduces both hospital admissions and mortality rates for HF and CRS patients after a one-year follow-up period.

Benefits of dapagliflozin in the whole spectrum of heart failure in clinical practice: the RICA registry.

Aims: To determine the projected benefits of dapagliflozin after an acute heart failure (HF) event in Spain. Methods: A multicenter and prospective study that included subjects aged 50 years or older consecutively admitted with HF to internal medicine departments in Spain. The projected clinical benefits of dapagliflozin were calculated via pooled analysis of the DAPA-HF and DELIVER trials. Results: A total of 5644 subjects were analyzed, of whom 79.2% were eligible for dapagliflozin, according to criteria of the DAPA-HF and DELIVER trials. Full implementation of dapagliflozin would imply a 1-year absolute risk reduction of 2.3% for death (number needed to treat = 43) and 5.7% (number needed to treat = 17) for HF rehospitalization. Conclusion: Treatment with dapagliflozin could significantly reduce HF burden in clinical practice.

Heart failure is a severe condition that is associated with a high risk of complications. This means that it is important to start using new therapies that have demonstrated a clinical benefit. Clinical trials have shown that dapagliflozin reduces the risk of developing these complications in patients with heart failure. However, it is important to find out whether the results of clinical trials are also seen in real-life populations. We estimated the potential benefits of dapagliflozin in people admitted to hospital more than once with heart failure. The study took place in Spain. Our data suggest that treatment with dapagliflozin could reduce the complications associated with heart failure in real-life patients.

Projected clinical benefits of dapagliflozin in patients with heart failure with preserved ejection fraction.

Aims: To address the projected clinical benefits of dapagliflozin among patients with heart failure (HF) with mildly reduced ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF). Methods: A multicenter, prospective, cohort study of patients ≥50 years admitted with HF to Spanish internal medicine departments. The projected clinical benefits of dapagliflozin were calculated from the DELIVER trial. Results: A total of 4049 patients were included; 3271 (80.8%) were eligible for dapagliflozin treatment, according to DELIVER criteria. Within 1 year after discharge, 22.2% were rehospitalized for HF and 21.6% died. Implementation of dapagliflozin would translate into an absolute risk reduction of 1.3% for mortality and 5.1% for HF readmission. Conclusion: HF patients with preserved or mildly reduced ejection fraction have a high risk of events. The use of dapagliflozin could substantially reduce the HF burden.

Heart failure (HF) with preserved ejection fraction is frequent in clinical practice, particularly in the elderly. In HF with preserved ejection fraction, the heart still pumps a similar proportion of blood, but the heart muscle has become thicker. This means there is less space inside the heart to fill with blood, so too little is pumped out each time. Until very recently, no drugs had been shown to provide significant benefits on the outcome of the condition or the chance of recovery for these patients. Fortunately, recent clinical trials have demonstrated that treatment with drugs called SGLT2 inhibitors (e.g., dapagliflozin) could reduce the chance of being admitted to hospital or dying from HF. We investigated the benefits for patients who took dapagliflozin after being admitted to hospital and had HF with mildly reduced or preserved ejection fraction. We saw substantial benefits in this population.

Projected effectiveness of dapagliflozin in heart failure with reduced ejection fraction in clinical practice.

Aim: To estimate the projected effectiveness of dapagliflozin in subjects with heart failure (HF) with reduced ejection fraction in clinical practice in Spain. Materials & methods: This multicenter cohort study included subjects aged 50 years or older consecutively hospitalized for HF in internal medicine departments in Spain. The projected clinical benefits of dapagliflozin were estimated based on results from the DAPA-HF trial. Results: A total of 1595 patients were enrolled, of whom 1199 (75.2%) were eligible for dapagliflozin. Within 1 year after discharge, 21.6% of patients eligible for dapagliflozin were rehospitalized for HF and 20.5% died. Full implementation of dapagliflozin led to an absolute risk reduction of 3.5% for mortality (number needed to treat = 28) and 6.5% (number needed to treat = 15) for HF readmission. Conclusion: Treatment with dapagliflozin in clinical practice may markedly reduce mortality and readmissions for HF.

Heart failure with reduced ejection fraction is a severe disease with a high risk of hospitalization and mortality. With this condition, the heart muscle cannot pump properly. This means that not enough blood is pumped from the heart, reducing the amount of oxygen to the body. Fortunately, there are treatments that reduce this risk, in patients with heart failure. SGLT2 inhibitors, including dapagliflozin, are among the first therapies given to patients with heart failure. In this study, we investigated the potential benefits of adding dapagliflozin to the treatment of patients admitted to the hospital in Spain for heart failure with reduced ejection fraction. Our data showed that dapagliflozin was able to reduce the risk of further events (e.g., heart attack) in these patients.

QT interval and short-term outcome in acute heart failure.

OBJECTIVE: To investigate the association of corrected QT (QTc) interval duration and short-term outcomes in patients with acute heart failure (AHF). METHODS: We analyzed AHF patients enrolled in 11 Spanish emergency departments (ED) for whom an ECG with QTc measurement was available. Patients with pace-maker rhythm were excluded. Primary outcome was 30-day all-cause mortality and secondary outcomes were need of hospitalization, in-hospital mortality and prolonged hospitalization (> 7 days). Association between QTc and outcomes was explored by restricted cubic spline (RCS) curves. Results were expressed as odds ratios (OR) and 95%CI adjusted by patients baseline and decompensation characteristics, using a QTc = 450 ms as reference. RESULTS: Of 1800 patients meeting entry criteria (median age 84 years (IQR = 77-89), 56% female), their median QTc was 453 ms (IQR = 422-483). The 30-day mortality was 9.7%, while need of hospitalization, in-hospital mortality and prolonged hospitalization were 77.8%, 9.0% and 50.0%, respectively. RCS curves found longer QTc was associated with 30-day mortality if > 561 ms, OR = 1.86 (1.00-3.45), and increased up to OR = 10.5 (2.25-49.1), for QTc = 674 ms. A similar pattern was observed for in-hospital mortality; OR = 2.64 (1.04-6.69), for QTc = 588 ms, and increasing up to OR = 8.02 (1.30-49.3), for QTc = 674 ms. Conversely, the need of hospitalization had a U-shaped relationship: being increased in patients with shorter QTc [OR = 1.45 (1.00-2.09) for QTc = 381 ms, OR = 5.88 (1.25-27.6) for the shortest QTc of 200 ms], and also increasing for prolonged QTc [OR = 1.06 (1.00-1.13), for QTc = 459 ms, and reaching OR = 2.15 (1.00-4.62) for QTc = 588 ms]. QTc was not associated with prolonged hospitalization. CONCLUSION: In ED AHF patients, initial QTc provides independent short-term prognostic information, with increasing QTc associated with increasing mortality, while both, shortened and prolonged QTc are associated with need of hospitalization.

The influence of comorbidities on the prognosis after an acute heart failure decompensation and differences according to ejection fraction: Results from the EAHFE and RICA registries.

OBJECTIVE: The role of comorbidities in heart failure (HF) outcome has been previously investigated, although mostly individually. We investigated the individual effect of 13 comorbidities on HF prognosis and looked for differences according to left-ventricular ejection fraction (LVEF), classified as reduced (HFrEF), mildly-reduced (HFmrEF) and preserved (HFpEF). METHODS: We included patients from the EAHFE and RICA registries and analysed the following comorbidities: hypertension, dyslipidaemia, diabetes mellitus (DM), atrial fibrillation (AF), coronary artery disease (CAD), chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), heart valve disease (HVD), cerebrovascular disease (CVD), neoplasia, peripheral artery disease (PAD), dementia and liver cirrhosis (LC). Association of each comorbidity with all-cause mortality was assessed by an adjusted Cox regression analysis that included the 13 comorbidities, age, sex, Barthel index, New York Heart Association functional class and LVEF and expressed as adjusted Hazard Ratios (HR) with 95% confidence intervals (95%CI). RESULTS: We analysed 8,336 patients (82 years-old; 53% women; 66% with HFpEF). Mean follow-up was 1.0 years. Respect to HFrEF, mortality was lower in HFmrEF (HR:0.74;0.64-0.86) and HFpEF (HR:0.75;0.68-0.84). Considering patients all together, eight comorbidities were associated with mortality: LC (HR:1.85;1.42-2.42), HVD (HR:1.63;1.48-1.80), CKD (HR:1.39;1.28-1.52), PAD (HR:1.37;1.21-1.54), neoplasia (HR:1.29;1.15-1.44), DM (HR:1.26;1.15-1.37), dementia (HR:1.17;1.01-1.36) and COPD (HR:1.17;1.06-1.29). Associations were similar in the three LVEF subgroups, with LC, HVD, CKD and DM remaining significant in the three subgroups. CONCLUSION: HF comorbidities are associated differently with mortality, LC being the most associated with mortality. For some comorbidities, this association can be significantly different according to the LVEF.

Effectiveness of sacubitril-varsartan versus angiotensin converting enzyme inhibitors in patients hospitalized for acute heart failure: a retrospective cohort study of the RICA registry.

BACKGROUND: Sacubitril-valsartan has been shown to reduce hospitalizations and mortality in patients with heart failure (HF) and reduced ejection fraction. The PIONEER-HF trial demonstrated that initiation of the drug during acute HF hospitalization reduced NT-proBNP levels and a post-hoc analysis of the trial found a reduction in HF hospitalizations and deaths. Real-life studies in the elderly population are scarce. The aim of our study was to assess the effectiveness of sacubitril-valsartan versus angiotensin converting enzyme inhibitors (ACEI) in elderly patients who initiate this treatment during hospitalization for acute HF. METHODS: We conducted a retrospective cohort study using the Spanish acute heart failure registry (RICA) comparing rehospitalizations and deaths at 3 months and 1 year among patients aged 70 years or older who had initiated treatment with sacubitril-valsartan during hospitalization for acute HF versus those treated with ACEI. RESULTS: One hundred and ninety-nine patients hospitalized between October 2016 and November 2020 were included, with a median age of 82 years and high rate of comorbidity. Of these, 107 were treated with sacubitril-valsartan and 92 with ACEI. The adjusted OR for readmission for HF at 3 months was 0.906 (95% CI: 0.241-3.404) and for the combined variable readmission for HF or death at 3 months was 0.696 (95% CI: 0.224-2.167). The adjusted OR for HF readmission at one year was 0.696 (95% CI: 0.224 -2.167). and for the combined variable HF readmission or death at one year 0.724 (95% CI: 0.325-1.612). CONCLUSION: Treatment with sacubitril-valsartan initiated early in hospitalization for HF in elderly patients with high comorbidity was associated with a trend towards a reduction in readmissions and death due to HF compared to treatment with ACEI, which did not reach statistical significance either at 3 months or 1 year of follow-up.

Beta-blocker use in patients with heart failure with preserved ejection fraction and sinus rhythm.

INTRODUCTION: Beta-adrenergic receptor blockers (beta-blockers) are frequently used for patients with heart failure (HF) with preserved ejection fraction (HFpEF), although evidence-based recommendations for this indication are still lacking. Our goal was to assess which clinical factors are associated with the prescription of beta-blockers in patients discharged after an episode of HFpEF decompensation, and the clinical outcomes of these patients. METHODS: We assessed 1078 patients with HFpEF and in sinus rhythm who had experienced an acute HF episode to explore whether prescription of beta-blockers on discharge was associated with one-year all-cause mortality or the composite endpoint of one-year all-cause death or HF readmission. We also examined the clinical factors associated with beta-blocker discharge prescription for such patients. RESULTS: At discharge, 531 (49.3%) patients were on beta-blocker therapy. Patients on beta-blockers more often had a prior diagnosis of hypertension and more comorbidity (including ischemic heart disease) and a better functional status, but less often a prior diagnosis of chronic obstructive pulmonary disease. These patients had a lower heart rate on admission and more often used angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, angiotensin receptor-neprilysin inhibitors and loop diuretics. One year after the index admission, 161 patients (15%) had died and 314 (29%) had experienced the composite endpoint. After multivariate adjustment, beta-blocker prescription was not associated with either all-cause mortality (HR=0.83 [95% CI 0.61-1.13]; p=0.236) or the composite endpoint (HR=0.98 [95% CI 0.79-1.23]; p=0.882). CONCLUSION: In patients with HFpEF in sinus rhythm, beta-blocker use was not related to one-year mortality or mortality plus HF readmission.

Antígeno carbohidrato 125 (CA125) como marcador pronóstico en ancianos con insuficiencia cardiaca aguda y fracción de eyección preservada / Carbohydrate antigen 125 (CA125) as a prognostic marker in the elderly with acute heart failure and preserved ejection fraction

Antecedentes:El antígeno carbohidrato 125 (CA125) ha emergido como un nuevo biomarcador en insuficiencia cardiaca. El objetivo del estudio es determinar si los niveles séricos de CA125 predicen la mortalidad y reingresos totales a un año en pacientes mayores de 70 años e insuficiencia cardiaca aguda (ICA) con fracción de eyección preservada (FEP).Métodos:Estudio observacional prospectivo multicéntrico, que incluyó a 359 pacientes (edad media 81,5 años). La variable de valoración principal fue la mortalidad total por todas las causas y lo reingresos totales por ICA a un año. El análisis de regresión binomial negativa se utilizó para evaluar la asociación entre los valores de CA125 y el pronóstico.Resultados:Al año de seguimiento, se registraron 87 muertes (24,2%). Los pacientes del cuartil inferior de CA125 presentaron una tasa bruta de mortalidad menor (14,4%, 26,7, 26,7 y 29,2; p=0,090). Tras un análisis multivariado, el valor de CA125 se asoció de forma casi lineal y positiva a un mayor riesgo de mortalidad (p=0,009). Dicha asociación fue también positiva pero estadísticamente límite en el caso de los reingresos totales por ICA (p=0,089).Conclusiones:En población mayor de 70 años hospitalizada por ICA con FEP, los niveles elevados de CA125 se asocian a un aumento del riesgo de muerte a un año de seguimiento. La asociación con los reingresos fue más incierta. Los niveles bajos de CA125 identifica un subgrupo de pacientes de bajo riesgo. (AU)

Background:Carbohydrate antigen 125 (CA125) has emerged as a new biomarker in heart failure. The objective of the study is to determine whether serum CA125 levels predict total mortality and readmissions at one year in patients >70 years old with acute heart failure (AHF) and preserved ejection fraction (PEF).Methods:Multicenter prospective observational study, which included 359 patients (mean age 81.5 years). The primary endpoint was total all-cause mortality and total readmissions for AHF at 1 year. A negative binomial regression technique was used to evaluate the association between CA125 and both endpoints.Results:At one year of follow-up, 87 deaths (24.2%) were registered. The patients in the lower quartile of CA125 had a lower crude mortality rate (14.4%, 26.7, 26.7, 29.2; p=0.09). After multivariate analysis, the CA125 value was positively associated with a higher risk (p=0.009). Such association was also positive but borderline significant for the risk of readmissions (p=0.089).Conclusions:In a population older than 70 years hospitalized for AHF with PEF, elevated levels of CA125 are associated with an increased risk of death at one year of follow-up. The association with readmission for AHF was more uncertain. Low levels of CA125 identifies a subgroup at low-risk. (AU)

Clinical Characteristics and Prognostic Relevance of Different Types of Caregivers for Elderly Patients with Acute Heart Failure-Analysis from the RICA Registry.

Background: Patients with heart failure encompass a heterogeneous group, but they are mostly elderly patients with a large burden of comorbid conditions. Objective: The aim of this study was to compare the clinical characteristics and the prognostic impact on hospital admissions and mortality in a population of patients with HF with different types of caregivers (family members, professionals, and the patient himself). Methods: We conducted an observational study from a prospective registry. Patients from the National Registry of Heart Failure (RICA), which belongs to the Working Group on Heart Failure and Atrial Fibrillation of the Spanish Society of Internal Medicine (SEMI), were included. Patients with heart failure were classified, according to the type of main caregiver, into four groups: the patient himself/herself, a partner, children, or a professional caregiver. A bivariable analysis was performed between the clinical, analytical, therapeutic, and prognostic characteristics of the different groups. The endpoints of the study were all-cause mortality at 1 year; mortality at 120 days; and the readmission rate for HF at 30 days, 120 days, and 1 year of follow-up. In all cases, the level of statistical significance was set at p < 0.05. Results: A total of 2147 patients were enrolled in this study; women represented 52.4%, and the mean age was 81 years. The partner was the caregiver for 703 patients, children were caregivers for 1097 patients, 199 patients had a professional caregiver, and only 148 patients were their own caregivers. Women were more frequently cared for by their children (65.8%) or a professional caregiver (61.8%); men were more frequently cared for by their spouses (68.7%) and more frequently served as their own caregivers (59.5%) (p < 0.001). No statistically significant differences were observed in relation to readmissions or mortality at one year of follow-up between the different groups. A lower probability of readmission and death was observed for patients who received care from a partner or children/relative, with log-rank scores of 11.2 with p= 0.010 and 10.8 with p = 0.013. Conclusions: Our study showed that the presence of a family caregiver for elderly patients with heart failure was associated with a lower readmission rate and a lower mortality rate at 120 days of follow-up. Our study also demonstrated that elderly patients with good cognitive and functional status can be their own caregivers, as they obtained good health outcomes in terms of readmission and mortality. More prospective studies and clinical trials are needed to evaluate the impact of different types of caregivers on the outcomes of patients with heart failure.

Prognostic Significance of the PROFUND Index on One Year Mortality in Acute Heart Failure: Results from the RICA Registry.

Background: Heart failure (HF) is a syndrome with high prevalence, mainly affecting elderly patients, where the presence of associated comorbidities is of great importance. Methods: An observational study from a prospective registry was conducted. Patients identified from the National Registry of Heart Failure (RICA), which belongs to the Working Group on Heart Failure and Atrial Fibrillation of the Spanish Society of Internal Medicine (SEMI), were included. The latter is a prospective, multicenter registry that has been active since 2008. It includes individual consecutive patients over 50 years of age with a diagnosis of HF at hospital discharge (acute decompensated or new-onset HF). Results: In total, 5424 patients were identified from the registry. Forty-seven percent were men and mean left ventricular ejection fraction (LVEF) was 51.4%; 1132 had a score of 0 to 2 according to the PROFUND index, 3087 had a score of 3 to 6, and 952 patients had a score of 7 to 10 points. In the sample, 252 patients had a score above 11 points. At the end of the year of follow-up, 61% of the patients died. This mortality increased proportionally as the PROFUND index increased, specifically 75% for patients with PROFUND greater than 11. The Kaplan-Meier survival curve shows that survival at one year progressively decreases as the PROFUND index value increases. Thus, subjects with scores greater than seven (intermediate-high and high-risk) presented the worst survival with a log rank of 0.96 and a p < 0.05. In the regression analysis, we found a higher risk of death from any cause at one year in the group with the highest risk according to the PROFUND index (score greater than 11 points (HR 1.838 (1.410−2.396)). Conclusions: The PROFUND index is a good index for predicting mortality in patients admitted for acute HF, especially in those subjects at intermediate to high risk with scores above seven. Future studies should seek to determine whether the PROFUND index score is simply a prognostic marker or whether it can also be used to make therapeutic decisions for those subjects with very high short-term mortality.

Causas de muerte en pacientes hospitalizados en servicios de medicina interna por insuficiencia cardíaca según la fracción de eyección. Registro RICA / Causes of death in hospitalized patients in internal medicine departments with heart failure according to ejection fraction. RICA registry

IntroducciónLos datos disponibles de las causas de muerte en pacientes ingresados por insuficiencia cardíaca en servicios de medicina interna y en población española según fracción de eyección reducida (FER), preservada (FEP) e intermedia (FEI) son escasos. Su estudio puede mejorar el conocimiento de estos pacientes y su pronóstico.MétodosEstudio de cohortes multicéntrico y prospectivo de 4.144 pacientes que ingresaron por insuficiencia cardíaca en unidades de medicina interna. Se registraron sus características clínicas, tasa de fallecimientos y sus causas agrupadas según FEP (≥ 50%), FEI (40-49%) y FER (<40%) durante una mediana de seguimiento de un año.ResultadosSe registraron 1.198 fallecimientos (29%), de los que 833 fallecieron por causas cardiovasculares (69,5%), fundamentalmente por insuficiencia cardíaca (50%) y por muerte súbita (7,5%) y 365 por causas no cardiovasculares (NoCV) (30,5%), sobre todo por infecciones (13%). La causa más frecuente y temprana en todos los grupos fue la insuficiencia cardíaca. Los pacientes con FEP tenían menor tasa de muerte súbita y mayor de infecciones (p <0,05). Las causas de muerte en FEI fueron más parecidas a las de FEP.ConclusionesLas causas de muerte en pacientes con insuficiencia cardíaca fueron diferentes dependiendo del tipo de fracción de eyección. Los pacientes con FEI y FEP, por su elevada comorbilidad y mayor frecuencia de muerte NoCV, son los que más se beneficiarían de un manejo integral por parte de medicina interna.

Carbohydrate antigen 125 (CA125) as a prognostic marker in the elderly with acute heart failure and preserved ejection fraction. / Antígeno carbohidrato 125 (CA125) como marcador pronóstico en ancianos con insuficiencia cardiaca aguda y fracción de eyección preservada.

BACKGROUND: Carbohydrate antigen 125 (CA125) has emerged as a new biomarker in heart failure. The objective of the study is to determine whether serum CA125 levels predict total mortality and readmissions at one year in patients >70 years old with acute heart failure (AHF) and preserved ejection fraction (PEF). METHODS: Multicenter prospective observational study, which included 359 patients (mean age 81.5 years). The primary endpoint was total all-cause mortality and total readmissions for AHF at 1 year. A negative binomial regression technique was used to evaluate the association between CA125 and both endpoints. RESULTS: At one year of follow-up, 87 deaths (24.2%) were registered. The patients in the lower quartile of CA125 had a lower crude mortality rate (14.4%, 26.7, 26.7, 29.2; p=0.09). After multivariate analysis, the CA125 value was positively associated with a higher risk (p=0.009). Such association was also positive but borderline significant for the risk of readmissions (p=0.089). CONCLUSIONS: In a population older than 70 years hospitalized for AHF with PEF, elevated levels of CA125 are associated with an increased risk of death at one year of follow-up. The association with readmission for AHF was more uncertain. Low levels of CA125 identifies a subgroup at low-risk.

Causes of death in hospitalized patients in internal medicine departments with heart failure according to ejection fraction. RICA registry. / Causas de muerte en pacientes hospitalizados en servicios de medicina interna por insuficiencia cardíaca según la fracción de eyección. Registro RICA.

INTRODUCTION: There are few data in the Spanish population about the causes of death in patients admitted to internal medicine departments for heart failure. Their study according to left ventricular ejection fraction (reduced: rEF, mid-range: mEF, and preserved: pEF) could improve the knowledge of patients and their prognosis. METHODS: Prospective multicentre cohort study of 4144 patients admitted with heart failure to internal medicine departments. Their clinical characteristics, mortality rate and causes were classified according to pEF (≥ 50%), mEF (40%-49%) and rEF (<40%). Patients were followed-up for a median of one year. RESULTS: There were 1198 deaths (29%). The cause of death was cardiovascular (CV) in 833 patients (69.5%), mainly heart failure (50%) and sudden cardiac death (7.5%). Non-cardiovascular (NoCV) causes were responsible for 365 deaths (30.5%). The most common NoCV causes were infections (13%). The most frequent and early cause in all groups was heart failure. Patients with pEF, compared to the other groups, had lower risk of sudden cardiac death and higher risk of infections (P <.05). The causes of death in patients with mrEF were closer to those with pEF. CONCLUSIONS: The causes of death in patients with heart failure were different depending on ejection fraction strata. Patients with mEF and pEF, due to their high comorbidity and higher frequency of NoCV death, would require comprehensive management by internal medicine.

[Influence of the degree of anaemia on the prognosis of older adults with heart failure (SPAN-HF study)]. / Influencia del grado de anemia en el pronóstico de los pacientes de edad avanzada con insuficiencia cardíaca (Estudio SPAN-HF).

OBJECTIVE: To assess whether a sustained optimal haemoglobin value in the 3 months after admission for heart failure (HF) decompensation reduces morbidity and mortality during the 12 months after admission for acute HF. PATIENTS AND METHOD: Retrospective study of the 1408 patients older than 65 years included in the RICA registry divided into 3 groups: no anaemia (group A), recovered anaemia (group B), and persistent anaemia (group C), according to haemoglobin levels on admission, and 3 months after discharge. Kaplan-Meier curves were constructed, comparing the groups using the log-rank test and a Cox regression model was performed to analyse survival. RESULTS: 578 (41.1%), 299 (21.2%) and 531 (37.7%) were included in groups A, B and C, respectively. We recorded a total of 768 deaths and readmissions. There were 23 (4%), 12 (4%) and 49 (9.2%), (p=.001) individuals who died due to HF and 154 (27%), 73 (24%) and 193 (36%) (P<.001) admissions for this pathology, respectively. Patients with persistent anaemia had a higher risk of death (RR 1.29, 95% CI 1.04-1.61, P=.024) or readmission (1.92, 95% CI 1.16-3, 19; P=.012) due to HF. CONCLUSIONS: Persistent anaemia in the months after admission for HF increases morbidity and mortality in the subsequent year.

Epidemiología de la insuficiencia cardiaca con fracción de eyección preservada: resultados del Registro RICA / Epidemiology of heart failure with preserved ejection fraction: Results from the RICA Registry

Introducción y objetivos: La caracterización de los pacientes con insuficiencia cardiaca (IC) con fracción de eyección preservada (IC-FEp) sigue teniendo interés. El objetivo fue conocer la prevalencia, las características clínicas y epidemiológicas de la IC-FEp, y sus cambios en los últimos años.MétodosAnalizamos el Registro RICA, de la Sociedad Española de Medicina Interna; estudio de cohorte multicéntrico y prospectivo de pacientes ingresados por IC, consecutivamente en servicios de medicina interna, durante un periodo de 11 años (2008-2018).ResultadosSe incluyeron 4.752 pacientes, 2957 (62,2%) con IC-FEp, proporción que se mantuvo constante durante todo el periodo. En comparación con los pacientes con IC y fracción de eyección reducida (IC-FEr), los pacientes con IC-FEp tienen: mayor edad, predominio de sexo femenino, etiología hipertensiva y valvular, distinto perfil de comorbilidades y peor capacidad funcional (menor índice de Barthel). La mayoría de pacientes recibía un tratamiento similar al de la IC-FEr (inhibidores del sistema renina-angiotensina-aldosterona y betabloqueantes). La mortalidad global al año de seguimiento fue del 24% en la IC-FEp y del 30% en la IC-FEr. En el análisis multivariante el riesgo de muerte fue superior en los pacientes con IC-FEr (HR: 1,84; IC 95%: [1,43-2,36]); la estancia hospitalaria fue inferior en la IC-FEp y no hubo diferencias en las re-hospitalizaciones.

Introduction and objectives: There is great interest in better characterizing patients with heart failure (HF) with preserved ejection fraction (HF-PEF). The objective of this study is to determine the prevalence, progression over time and to describe the clinical and epidemiological characteristics of patients with HF-PEF.MethodsFrom the National Registry of Heart Failure (RICA, prospective multicentre cohort study) we analysed patients consecutively admitted for HF in Internal Medicine wards over a period of 11 years (2008-2018).Results4752 patients were included, 2957 (62.2%) with preserved ejection fraction. This prevalence remained constant from 2008 to 2019. Compared to patients with HF and reduced ejection fraction (HF-REF) patients with HF-PEF are older, more are female, there is a higher prevalence of hypertensive and valvular aetiology, they have a profile of different comorbidities and worse functional status. A high proportion of patients receive disease-modifying treatment for IC-REF (renin-angiotensin-aldosterone system inhibitors and beta-blockers). The overall mortality after one-year follow-up was 24% and 30% in the HF-PEF and the HF-REF, respectively. In the multivariate analysis, the risk of death was higher in patients with HF-REF compared to HF-PEF (OR: 1.84; 95% CI: [1.43-2.36]). The length of hospital stay was also lower in the HF-PEF patients but there were no differences in re-hospitalizations. (AU)

Comorbidities and their implications in patients with and without type 2 diabetes mellitus and heart failure with preserved ejection fraction. Findings from the rica registry.

AIM: To determine if patients with heart failure and preserved ejection fraction (HFpEF) and type 2 diabetes mellitus (T2DM) have a higher comorbidity burden than those without T2DM, if other comorbidities are preferentially associated with T2DM and if these conditions confer a worse patient prognosis. METHODS AND RESULTS: Cohort study based on the RICA Spanish Heart Failure Registry, a multicentre, prospective registry that enrols patients admitted for decompensated HF and follows them for 1 year. We selected only patients with HFpEF, classified as having or not having T2DM and performed an agglomerative hierarchical clustering based on variables such as the presence of arrhythmia, chronic obstructive pulmonary disease, dyslipidemia, liver disease, stroke, dementia, body mass index, haemoglobin levels, estimated glomerular filtration rate and systolic blood pressure. A total of 1934 patients were analysed: 907 had T2DM (mean age 78.4 ± 7.6 years) and 1027 did not (mean age 81.4 ± 7.6 years). The analysis resulted in four clusters in patients with T2DM and three in the reminder. All clusters of patients with T2DM showed higher BMI and more kidney disease and anaemia than those without T2DM. Clusters of patients without T2DM had neither significantly better nor worse outcomes. However, among the T2DM patients, clusters 2, 3 and 4 all had significantly poorer outcomes, the worst being cluster 3 (HR 2.0, 95% CI 1.36-2.93, P = .001). CONCLUSIONS: Grouping our patients with HFpEF and T2DM into clusters based on comorbidities revealed a greater disease burden and prognostic implications associated with the T2DM phenotype, compared with those without T2DM.
