Outcomes of patients with heart failure followed in units accredited by the SEC-Excelente-IC quality program according to the type of unit.

INTRODUCTION AND OBJECTIVES: The development of specific heart failure (HF) units has improved the management of patients with this disease due to improved organization and resource management. The Spanish Society of Cardiology (SEC) has defined 3 types of HF units (community, specialized, and advanced) based on their complexity and service portfolio. Our aim was to compare the characteristics, treatment, and outcomes of patients with HF according to the type of unit. METHODS: We analyzed data from the SEC-Excelente-IC quality accreditation program registry, with 1716 patients consecutively included in two 1-month cutoffs (March and October) from 2019 to 2021 by 45 SEC-accredited HF units. We compared the characteristics, treatment and 1-year outcomes between the 3 types of units. RESULTS: Of the 1716 patients, 13.2% were treated in community units, 65.9% in specialized units, and 20.9% in advanced units. The rates of mortality (27.5 vs 15.5/100 patients-year; P < .001), admissions for HF (39.7 vs 29.2/100 patients-year; P = .019), total decompensations (56.1 vs 40.5/100 patients-year; P = .003), and combined death/admission for HF (45.2 vs 31.4/100 patients-year; P = .005) were higher in community units than in specialized/advanced units. Follow-up in a community unit was an independent predictor of higher mortality and admissions at 1 year. CONCLUSIONS: Compared with follow-up by more specialized units, follow-up in a community unit was associated with a higher decompensation rate and increased 1-year mortality.

Colchicine in acute heart failure: Rationale and design of a randomized double-blind placebo-controlled trial (COLICA).

AIMS: Heart failure (HF) elicits a pro-inflammatory state, which is associated with impaired clinical outcomes, but no anti-inflammatory therapies have demonstrated a clinical benefit yet. Inflammatory pathways related with the interleukin-1 axis are overactivated during episodes of acute HF. Colchicine, an anti-inflammatory drug with proven benefits in acute pericarditis and ischaemic heart disease, may target this inflammatory response. This study aims to assess the efficacy of colchicine in acute HF patients. METHODS: COLICA is a multicentre, randomized, double-blind, placebo-controlled trial enrolling 278 patients across 12 sites. Patients presenting with acute HF, clinical evidence of congestion requiring ≥40 mg of intravenous furosemide and N-terminal pro-B-type natriuretic peptide (NT-proBNP) >900 pg/ml, are eligible for participation. Patients are enrolled irrespective of left ventricular ejection fraction, HF type (new-onset or not) and setting (hospital or outpatient clinic). Patients are randomized 1:1 within the first 24 h of presentation to either placebo or colchicine, with an initial loading dose of 2 mg followed by 0.5 mg every 12 h for 8 weeks (reduced dose if <70 kg, >75 years old, or glomerular filtration rate <50 ml/min/1.73 m2). The primary efficacy endpoint is the time-averaged proportional change in NT-proBNP concentrations from baseline to week 8. Key secondary and exploratory outcomes include symptoms, diuretic use, worsening HF episodes, related biomarkers of cardiac stress and inflammation, total and cardiovascular readmissions, mortality and safety events. CONCLUSION: COLICA will be the first randomized trial testing the efficacy and safety of colchicine for acute HF.

Diferencias clínicas entre la amiloidosis cardiaca por transtirretina y la cardiopatía hipertensiva / Clinical differences between transthyretin cardiac amyloidosis and hypertensive heart disease

Introducción: Un porcentaje importante de pacientes finalmente diagnosticados de amiloidosis cardIaca por transtirretina (ATTR) fueron previamente diagnosticados de cardiopatía hipertensiva (CHTA), ya que ambas enfermedades suelen cursar con insuficiencia cardíaca (IC) con fracción de eyección preservada (ICFEp) e hipertrofia ventricular. Nuestros objetivos fueron evaluar las diferencias clínicas, electrocardiográficas y ecocardiográficas, y analizar si existe un pronóstico diferencial entre ambas entidades nosológicas. Material y métodos: Se incluyeron retrospectivamente todos los pacientes con CHTA a los que se solicitó una gammagrafía cardíaca con 99mTc-Difosfonatos (GDPD) y estudio de cadenas ligeras en sangre y orina para despistaje de ATTR en nuestro centro, en el periodo 2016-2021. Para el análisis, se excluyeron aquellos diagnosticados de otros tipos de amiloidosis. Resultados: Se analizaron un total de 72 pacientes: 33 fueron diagnosticados de ATTR y 39 de CHTA, finalmente. Los pacientes con ATTR presentaron mayores niveles de troponina I ultrasensible (TnI-US) y propéptido natriurético cerebral N-terminal (NT-ProBNP); en electrocardiograma (ECG) presentaron más frecuentemente patrón de seudoinfarto y alteraciones de la conducción; en ecocardiograma transtorácico (ETT) presentaron mayor grado de hipertrofia ventricular, disfunción ventricular izquierda y parámetros de peor función diastólica, con presiones de llenado más elevadas. En el seguimiento a 4 años, el grupo de ATTR mostró mayor necesidad de marcapasos (MCP), sin evidenciarse evidencias en cuanto a mortalidad, desarrollo de fibrilación auricular o más ingresos por IC. Conclusiones: En nuestra serie, los pacientes con ATTR presentaron diferencias clínicas, electrocardiográficas y ecocardiográficas respecto a aquellos con CHTA, con mayor riesgo necesidad de MCP en el seguimiento.(AU)

Introduction: A significant percentage of patients eventually diagnosed with cardiac transthyretin amyloidosis (TTRA) was previously diagnosed with hypertensive heart disease (HHD), since both conditions usually present with heart failure (HF) with preserved ejection fraction (HFpEF) and ventricular hypertrophy. Our objectives were to evaluate the clinical, electrocardiographic and echocardiographic differences, and to analyse whether there exists a differential prognosis between these two nosological entities. Materials and methods: We retrospectively included all patients with HHD for whom a cardiac scintigraphy with 99mTc-diphosphonate (GDPD) and a free light chains test in blood and urine were ordered for ATTR screening in our centre, in the period between 2016 and 2021. Those diagnosed with other types of amyloidosis were excluded from the analysis. Results: A total of 72 patients were analyzed: 33 were finally diagnosed with TTRA and 39 with CHTA. Patients with TTRA had higher levels of ultrasensitive troponin I (TnI-US) and N-terminal brain natriuretic propeptide (NT-ProBNP); in electrocardiography (ECG) they presented a pseudo-infarction pattern more frequently as well as conduction disturbances; in echocardiography (TTE) they presented a higher degree of ventricular hypertrophy, left ventricular dysfunction and worse diastolic function parameters, with elevated filling pressures. In the 4-year follow-up, the ATTR group showed greater need for pacemaker (PCM), with no evidence regarding mortality, development of atrial fibrillation (AF), or more admissions for heart failure (HF). Conclusions: In our series, patients with TTRA showed clinical, electrocardiographic and echocardiographic differences compared to patients with HHD, with increased risk of need for PCM.(AU)

Hospitalizaciones y eventos por insuficiencia cardiaca sistólica y diastólica en España entre 2016 y 2019. Un estudio de base poblacional / Hospital admissions and outcomes for systolic and diastolic heart failure in Spain between 2016 and 2019: A population-based study

Antecedentes y objetivos: En España carecemos de datos poblacionales de hospitalizaciones por insuficiencia cardiaca (IC) según sea sistólica o diastólica. Analizamos las diferencias clínicas, en mortalidad intrahospitalaria y reingresos de causa cardiovascular a los 30 días entre ambos tipos. Métodos: Estudio observacional retrospectivo de pacientes dados de alta con el diagnóstico principal de IC de los hospitales del Sistema Nacional de Salud entre 2016 y 2019, distinguiendo entre IC sistólica y diastólica. La fuente de datos fue el conjunto mínimo básico de datos del Ministerio de Sanidad. Se calcularon las razones de mortalidad intrahospitalaria y de reingreso a los 30 días estandarizadas por riesgo usando sendos modelos de regresión logística multinivel de ajuste de riesgo. Resultados: Se seleccionaron 190.200 episodios de IC. De ellos, 163.727 (86,1%) fueron por IC diastólica y se caracterizaron por presentar mayor edad, mayor proporción de mujeres, de diabetes y de insuficiencia renal que los de IC sistólica. Según los modelos de ajuste de riesgo la IC diastólica, frente a la sistólica, se comportó como un factor protector de mortalidad intrahospitalaria (odds ratio [OR]: 0,79; intervalo de confianza del 95% [IC 95%]: 0,75-0,83; p<0,001) y de reingreso de causa cardiovascular a los 30 días (OR: 0,93; IC 95%: 0,88-0,97; p0,002). Conclusiones: En España, entre 2016 y 2019, los episodios de hospitalización por IC fueron mayoritariamente por IC diastólica. Según los modelos de ajuste de riesgo la IC diastólica, con respecto a la sistólica, fue un factor protector de mortalidad intrahospitalaria y de reingreso de causa cardiovascular a los 30 días.(AU)

Background and purpose: In Spain there is a lack of population data that specifically compare hospitalization for systolic and diastolic heart failure (HF). We assessed clinical characteristics, in-hospital mortality and 30-day cardiovascular readmission rates differentiating by HF type. Methods: We conducted a retrospective observational study of patients discharged with the principal diagnosis of HF from The National Health System’ acute hospital during 2016-2019, distinguishing between systolic and diastolic HF. The source of the data was the Minimum Basic Data Set. The risk-standardized in-hospital mortality ratio and risk-standardized 30-day cardiovascular readmission ratio were calculated using multilevel risk adjustment models. Results: The 190,200 episodes of HF were selected. Of these, 163,727 (86.1%) were classified as diastolic HF and were characterized by older age, higher proportion of women, diabetes mellitus, dementia and renal failure than those with systolic HF. In the multilevel risk adjustment models, diastolic HF was a protective factor for both in-hospital mortality (odds ratio [OR]: 0.79; 95% confidence interval [CI]: 0.75-0.83; P<.001) and 30-day cardiovascular readmission versus systolic HF (OR: 0.93; 95% CI: 0.88-0.97; P=.002). Conclusions: In Spain, between 2016 and 2019, hospitalization episodes for HF were mostly due to diastolic HF. According to the multilevel risk adjustment models, diastolic HF compared to systolic HF was a protective factor for both in-hospital mortality and 30-day cardiovascular readmission.(AU)

Gender differences in clinical features and outcomes of patients over 75 years presenting with acute heart failure. Results of a nationwide study (2016-2019).

BACKGROUND: Heart failure (HF) is a major health problem in Western countries, and a leading cause of hospitalizations and death. There is a scarcity of data on the influence of sex on HF outcomes in elderly patients. The aim of the present study was to analyze differences between men and women in clinical characteristics, in-hospital mortality, 30-day HF readmission rates, cardiovascular mortality and HF readmission rates at 1 year after discharge in patients older than 75 years hospitalized for HF in Spain. METHODS: Retrospective analysis of patients discharged with a main diagnosis of HF from all Spanish public hospitals between 2016 and 2019. Patients aged 75 years or older were selected, and a comparison was made between male and female patients. RESULTS: From 2016 to 2019, a total of 354,786 episodes of HF in this age subgroup were identified, 59.2% being women. The overall mean age was 85.2 ± 5.4 years, being higher in women (85.9 ± 5.5 vs. 84.2 ± 5.3 years, p < 0.001). Risk-adjusted in-hospital mortality was lower in women (odds ratio [OR]: 0.96, 95% confidence interval [CI]: 0.92-0.97; p < 0.001). Female sex also showed a protective effect for 30-day readmissions, with an OR of 1.06 (95% CI: 1.04-1.09; p < 0.001). One-year cardiovascular mortality (24.1% vs. 25.0%; p < 0.001) and one-year HF readmission rates (30.8% vs. 31.6%; p = 0.001) were lower in women. CONCLUSIONS: Almost 60% of hospital admissions for HF in people aged 75 years or older between 2016 and 2019 in Spain were female patients. Female sex seems to play a protective role on in-hospital mortality and the rate of admissions and mortality at 1 year after discharge.

Characteristics of women with type 2 diabetes and heart failure in Spain. The DIABET-IC study.

BACKGROUND: Heart failure (HF) is the second most common initial presentation of cardiovascular disease in people with type 2 diabetes mellitus (T2DM). T2DM carries an increased risk of HF in women. The aim of this study is to analyze the clinical characteristics and the treatment received by women with HF and T2DM in Spain. METHODS: The DIABET-IC study included 1517 patients with T2DM in 2018-2019 in Spain, in 30 centers, which included the first 20 patients with T2DM seen in cardiology and endocrinology clinics. They underwent clinical evaluation, echocardiography, and analysis, with a 3-year follow-up. Baseline data are presented in this study. RESULTS: 1517 patients were included (501 women; aged 67.28 ± 10.06 years). Women were older (68.81 ± 9.90 vs. 66.53 ± 10.06 years; p < 0.001) and had a lower frequency of a history of coronary disease. There was a history of HF in 554 patients, which was more frequent in women (38.04% vs. 32.86%; p < 0.001), and preserved ejection fraction being more frequent in them (16.12% vs. 9.00%; p < 0.001). There were 240 patients with reduced ejection fraction. Women less frequently received treatment with angiotensin converting enzyme inhibitors (26.20% vs. 36.79%), neprilysin inhibitors (6.00% vs. 13.51%), mineralocorticoid receptor antagonists (17.40% vs. 23.08%), beta-blockers (52.40% vs. 61.44%), and ivabradine (3.60% vs. 7.10%) (p < 0.001 for all), and 58% received guideline-directed medical therapy. CONCLUSIONS: A selected cohort with HF and T2DM attending cardiology and endocrinology clinics did not receive optimal treatment, and this finding was more pronounced in women.

[Clinical differences between transthyretin cardiac amyloidosis and hypertensive heart disease]. / Diferencias clínicas entre la amiloidosis cardiaca por transtirretina y la cardiopatía hipertensiva.

INTRODUCTION: A significant percentage of patients eventually diagnosed with cardiac transthyretin amyloidosis (TTRA) was previously diagnosed with hypertensive heart disease (HHD), since both conditions usually present with heart failure (HF) with preserved ejection fraction (HFpEF) and ventricular hypertrophy. Our objectives were to evaluate the clinical, electrocardiographic and echocardiographic differences, and to analyse whether there exists a differential prognosis between these two nosological entities.

In the 4-year follow-up, the ATTR group showed greater need for pacemaker (PCM), with no evidence regarding mortality, development of atrial fibrillation (AF), or more admissions for heart failure (HF). CONCLUSIONS: In our series, patients with TTRA showed clinical, electrocardiographic and echocardiographic differences compared to patients with HHD, with increased risk of need for PCM.

The Worsening of Heart Failure with Reduced Ejection Fraction: The Impact of the Number of Hospital Admissions in a Cohort of Patients.

BACKGROUND: Worsening heart failure (WFH) includes heart failure (HF) hospitalisation, representing a strong predictor of mortality in patients with heart failure with reduced ejection fraction (HFrEF). However, there is little evidence analysing the impact of the number of previous HF admissions. Our main objective was to analyse the clinical profile according to the number of previous admissions for HF and its prognostic impact in the medium and long term. METHODS: A retrospective study of a cohort of patients with HFrEF, classified according to previous admissions: cohort-1 (0-1 previous admission) and cohort-2 (≥2 previous admissions). Clinical, echocardiographic and therapeutic variables were analysed, and the medium- and long-term impacts in terms of hospital readmissions and cardiovascular mortality were assessed. A total of 406 patients were analysed. RESULTS: The mean age was 67.3 ± 12.6 years, with male predominance (73.9%). Some 88.9% (361 patients) were included in cohort-1, and 45 patients (11.1%) were included in cohort-2. Cohort-2 had a higher proportion of atrial fibrillation (49.9% vs. 73.3%; p = 0.003), chronic kidney disease (36.3% vs. 82.2%; p < 0.001), and anaemia (28.8% vs. 53.3%; p = 0.001). Despite having similar baseline ventricular structural parameters, cohort-1 showed better reverse remodelling. With a median follow-up of 60 months, cohort-1 had longer survival free of hospital readmissions for HF (37.5% vs. 92%; p < 0.001) and cardiovascular mortality (26.2% vs. 71.9%; p < 0.001), with differences from the first month. CONCLUSIONS: Patients with HFrEF and ≥2 previous admissions for HF have a higher proportion of comorbidities. These patients are associated with worse reverse remodelling and worse medium- and long-term prognoses from the early stages, wherein early identification is essential for close follow-up and optimal intensive treatment.

Impact of Advanced Age on the Incidence of Major Adverse Cardiovascular Events in Patients with Type 2 Diabetes Mellitus and Stable Coronary Artery Disease in a Real-World Setting in Spain.

Patients with type 2 diabetes mellitus (T2DM) and coronary artery disease (CAD) without myocardial infarction (MI) or stroke are at high risk for major cardiovascular events (MACEs). We aimed to provide real-world data on age-related clinical characteristics, treatment management, and incidence of major cardiovascular outcomes in T2DM-CAD patients in Spain from 2014 to 2018. We used EHRead® technology, which is based on natural language processing and machine learning, to extract unstructured clinical information from electronic health records (EHRs) from 12 hospitals. Of the 4072 included patients, 30.9% were younger than 65 years (66.3% male), 34.2% were aged 65-75 years (66.4% male), and 34.8% were older than 75 years (54.3% male). These older patients were more likely to have hypertension (OR 2.85), angina (OR 1.64), heart valve disease (OR 2.13), or peripheral vascular disease (OR 2.38) than those aged <65 years (p < 0.001 for all comparisons). In general, they were also more likely to receive pharmacological and interventional treatments. Moreover, these patients had a significantly higher risk of MACEs (HR 1.29; p = 0.003) and ischemic stroke (HR 2.39; p < 0.001). In summary, patients with T2DM-CAD in routine clinical practice tend to be older, have more comorbidities, are more heavily treated, and have a higher risk of developing MACE than is commonly assumed from clinical trial data.

Adverse Clinical Outcomes and Associated Predictors in Rivaroxaban-Treated Atrial Fibrillation Patients With Renal Impairment.

Renal impairment confers worse prognosis in patients with atrial fibrillation (AF) but there is scarce evidence about the influence of direct-acting oral anticoagulants in routine clinical practice. Herein, we compared clinical outcomes between patients with AF with and without renal impairment on rivaroxaban and investigated predictors for clinical outcomes in patients with AF with renal impairment. This was a multicenter study including patients with AF on rivaroxaban for at least 6 months. During 2.5 years follow-up, ischemic strokes (IS)/transient ischemic attacks (TIA)/systemic embolisms (SE)/myocardial infarctions (MI), major bleeding, and major adverse cardiovascular events (MACE) were recorded. Creatinine clearance (CrCl) was estimated using the Cockroft-Gault equation, renal impairment was defined as a CrCl <60 ml/min, and 1,433 patients (34.8% with CrCl <60 ml/min) were included. Patients with CrCl <60 ml/min showed higher event rates for major bleeding (1.87%/year vs 0.62%/year; p = 0.003) and MACE (1.97%/year vs 0.62%/year; p = 0.002) but similar event rates for IS/TIA/SE/MI (0.66%/year vs 0.67%/year; p = 0.955). In patients with renal impairment, CHA2DS2-VASc was associated with higher risk of IS/TIA/SE/MI; HAS-BLED and any dependency level were associated with higher risk of major bleeding; and male gender and heart failure were associated with higher risk of MACE. Antiplatelets were independently associated with increased risk of IS/TIA/SE/MI and MACE. In conclusion, in patients with AF on rivaroxaban, the incidence of IS/TIA/SE/MI did not increase in those with renal impairment, suggesting that rivaroxaban may be an effective option in this subgroup. In patients with AF, male gender, heart failure, dependency, antiplatelets, CHA2DS2-VASc, and HAS-BLED were associated with increased risk of adverse outcomes.

Improvement of left ventricular ejection fraction in patients with heart failure with reduced ejection fraction: Predictors and clinical impact / Impacto clínico a medio plazo de la mejoría de la fracción de eyección ventricular izquierda en pacientes con insuficiencia cardiaca con fracción de eyección reducida

Background A percentage of patients with heart failure with reduced ejection fraction (HFrEF) improve left ventricular ejection fraction (LVEF) in the evolution. This entity, defined for the first time in an international consensus as heart failure with improved ejection fraction (HFimpEF), could have a different clinical profile and prognosis than HFrEF. Our main aim was to analyze the differential clinical profile between the two entities, as well as the mid-term prognosis. Material-methods Prospective study of a cohort of patients with HFrEF who had echocardiographic data at baseline and follow-up. A comparative analysis of patients who improved LVEF with those who did not was made. Clinical, echocardiographic and therapeutic variables were analyzed, and the mid-term impact in terms of mortality and hospital readmissions for HF was assessed. Results Ninety patients were analyzed. Mean age was 66.5(10.4) years, with a male predominance (72.2%). Forty five patients (50%) improved LVEF (Group-1,HFimpEF) and forty five patients (50%) sustained reduced LVEF (Group-2,HFsrEF). The mean time to LVEF improvement in Group-1 was 12.6(5.7) months. Group-1 had a more favorable clinical profile: lower prevalence of cardiovascular risk factors, higher prevalence of de novo HF (75.6% vs. 42.2%; p<0.05), lower prevalence of ischemic etiology (22.2% vs. 42.2%; p<0.05), with less basal dilatation of the left ventricle. At the end of follow-up (mean 19(1) months) Group-1 had a lower hospital readmission rate (3.1% vs. 26.7%; p<0.01), as well as lower mortality (0% vs. 24.4%; p<0.01). Conclusion Patients with HFimpEF seem to have a better mid-term prognosis in terms of reduced mortality and hospital admissions. This improvement could be conditioned by the clinical profile of patients HFimpEF (AU)

Introducción Un porcentaje de pacientes con insuficiencia cardiaca y fracción de eyección reducida (IC-FEr) mejoran la fracción de eyección ventricular izquierda (FEVI) en la evolución. Esta entidad se ha definido por primera vez en un consenso internacional como insuficiencia cardiaca y fracción de eyección mejorada (IC-FEm), y podría tener un perfil y pronóstico diferente que IC-FEr. Nuestro objetivo fue analizar el perfil de ambas entidades y su pronóstico a medio plazo. Material y métodos Estudio prospective de una cohorte de pacientes con IC-FEr que tenían datos ecocardiográficos basales y en el seguimiento. Se hizo un análisis comparativo de pacientes con IC-FEm y pacientes con insuficiencia cardiaca y IC-FEpr. Se analizaron variables clínicas, ecocardiográficas y de tratamiento; el impacto clínico a medio plazo se analizó en términos de mortalidad y reingresos hospitalarios por insuficiencia cardiaca. Resultados Se analizaron 90 pacientes, edad media 66,5 (10,4) años (72,2% mujeres). La mitad de los pacientes mejoraron su FEVI, con un tiempo medio hasta la mejoría de 12,6 (5,7) meses. El grupo IC-FEm tenía un perfil clínico más favorable: menor proporción de factores de riesgo cardiovascular, prevalencia más elevada de IC-novo (75,6 vs. 42,2%; p < 0,05), y menor proporción de isquemia (22,2 vs. 42.2%; p < 0,05). Los pacientes con IC-FEm en el seguimiento a medio plazo tenían menor tasa de reingresos (3,1 vs. 26,7%; p < 0,01), y mortalidad (0 vs. 24,4%; p < 0,01). Conclusión Pacientes con IC-FEm parecen tener un mejor pronóstico en términos de mortalidad y reingresos hospitalarios por insuficiencia cardiaca (IC). Esta mejoría clínica podría estar condicionada por el perfil de los pacientes con IC-FEm (AU)

Characteristics and in-hospital mortality of elderly patients with heart failure in Spanish hospitals.

BACKGROUND: The prevalence of heart failure (HF) increases with age, and it is one of the leading causes of hospitalization and death in older patients. However, there are little data on in-hospital mortality in patients with HF ≥ 75 years in Spain. METHODS: A retrospective analysis of the Spanish Minimum Basic Data Set was performed, including all HF episodes discharged from public hospitals in Spain between 2016 and 2019. Coding was performed using the International Classification of Diseases, 10th Revision. Patients ≥ 75 years with HF as the principal diagnosis were selected. We calculated: (1) the crude in-hospital mortality rate and its distribution according to age and sex; (2) the risk-standardized in-hospital mortality ratio; and (3) the association between in-hospital mortality and the availability of an intensive cardiac care unit (ICCU) in the hospital. RESULTS: We included 354,792 HF episodes of patients over 75 years. The mean age was 85.2 ± 5.5 years, and 59.2% of patients were women. The most frequent comorbidities were renal failure (46.1%), diabetes mellitus (35.5%), valvular disease (33.9%), cardiorespiratory failure (29.8%), and hypertension (26.9%). In-hospital mortality was 12.7%, and increased with age [odds ratio (OR) = 1.07, 95% CI: 1.07-1.07, P < 0.001] and was lower in women (OR = 0.96, 95% CI: 0.92-0.97, P < 0.001). The main predictors of mortality were the presence of cardiogenic shock (OR = 19.5, 95% CI: 16.8-22.7, P < 0.001), stroke (OR = 3.5, 95% CI: 3.0-4.0, P < 0.001) and advanced cancer (OR = 2.6, 95% CI: 2.5-2.8, P < 0.001). In hospitals with ICCU, the in-hospital risk-adjusted mortality tended to be lower (OR = 0.85, 95% CI: 0.72-1.00, P = 0.053). CONCLUSIONS: In-hospital mortality in patients with HF ≥ 75 years between 2016 and 2019 was 12.7%, higher in males and elderly patients. The main predictors of mortality were cardiogenic shock, stroke, and advanced cancer. There was a trend toward lower mortality in centers with an ICCU.

Improvement of left ventricular ejection fraction in patients with heart failure with reduced ejection fraction: Predictors and clinical impact.

BACKGROUND: A percentage of patients with heart failure with reduced ejection fraction (HFrEF) improve left ventricular ejection fraction (LVEF) in the evolution. This entity, defined for the first time in an international consensus as heart failure with improved ejection fraction (HFimpEF), could have a different clinical profile and prognosis than HFrEF. Our main aim was to analyze the differential clinical profile between the two entities, as well as the mid-term prognosis. MATERIAL-METHODS: Prospective study of a cohort of patients with HFrEF who had echocardiographic data at baseline and follow-up. A comparative analysis of patients who improved LVEF with those who did not was made. Clinical, echocardiographic and therapeutic variables were analyzed, and the mid-term impact in terms of mortality and hospital readmissions for HF was assessed. RESULTS: Ninety patients were analyzed. Mean age was 66.5(10.4) years, with a male predominance (72.2%). Forty five patients (50%) improved LVEF (Group-1,HFimpEF) and forty five patients (50%) sustained reduced LVEF (Group-2,HFsrEF). The mean time to LVEF improvement in Group-1 was 12.6(5.7) months. Group-1 had a more favorable clinical profile: lower prevalence of cardiovascular risk factors, higher prevalence of de novo HF (75.6% vs. 42.2%; p<0.05), lower prevalence of ischemic etiology (22.2% vs. 42.2%; p<0.05), with less basal dilatation of the left ventricle. At the end of follow-up (mean 19(1) months) Group-1 had a lower hospital readmission rate (3.1% vs. 26.7%; p<0.01), as well as lower mortality (0% vs. 24.4%; p<0.01). CONCLUSION: Patients with HFimpEF seem to have a better mid-term prognosis in terms of reduced mortality and hospital admissions. This improvement could be conditioned by the clinical profile of patients HFimpEF.

One-year readmissions for circulatory diseases and in-hospital mortality after an index episode of heart failure in elderly patients. A nationwide data from public hospitals in Spain between 2016 and 2018.

INTRODUCTION: Heart failure (HF) is one of the leading causes of hospitalization and death in elderly patients. However, there is limited evidence on readmission and mortality 1-year after discharge for HF. METHODS: Retrospective analysis of the Minimum Basic Data Set, including HF episodes, discharged from Spanish hospitals between 2016 and 2018 in ≥ 75 years. We calculated: (a) the rate of readmissions due to circulatory system diseases (CSD) 365 days after index episode; (b) in-hospital mortality in readmissions; and (c) predictors of mortality and readmission. RESULTS: We included 178,523 patients (59.2% women) aged 85.1 ± 5.5 years. The most frequent comorbidities were arrhythmias (56.0%) and renal failure (39.5%). During the follow-up, 48,932 patients (27.4%) had at least one readmission for CSD and a crude rate of 40.2%, the most frequent one HF (52.8%). The median between the date of readmission and discharge from the last admission was 70 days [IQI 24; 171] for the first readmission. The most relevant predictors of the number of readmissions were valvular heart disease and myocardial ischemia. During the readmissions, 26,757 patients (79.1%) died, representing a cumulative in-hospital mortality of 47,945 (26.9%). The factors in the index episode predictors of mortality during readmissions were cardio-respiratory failure and stroke. The number of readmissions was a risk factor for in-hospital mortality (OR 1.13; 95% CI 1.11-1.14). CONCLUSIONS: The readmission rate for CSD 1-year after the index episode of HF in patients ≥ 75 years was 28.4%. The cumulative in-hospital mortality rate during the readmissions was 26.9%, and the number of rehospitalizations was identified as one of the main predictors of mortality.
