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.

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.

Mortality risk factors in patients with SARS-CoV-2 infection and atrial fibrillation: Data from the SEMI-COVID-19 registry. / Factores de riesgo de mortalidad en pacientes con infección por SARS-CoV-2 y fibrilación auricular: datos del registro SEMI-COVID-19.

INTRODUCTION: Atrial fibrillation and associated comorbidities pose a risk factor for mortality, morbidity and development of complications in patients admitted for COVID-19.

The association with readmission for AHF was more uncertain. Low levels of CA125 identifies a subgroup at low-risk.

Tackling frailty at primary care: evaluation of the effectiveness of a multicomponent intervention through a randomised controlled trial: study protocol.

INTRODUCTION: This project focuses on how frailty is addressed in primary healthcare (PHC) and will evaluate the effectiveness of a multifactorial intervention (considering the appropriateness of the pharmaceutical prescription, the nutritional care provided and the exercise intervention) for persons with frailty, in terms of improving their functional capacity and reducing the incidence of adverse events related to frailty. The final evaluation will be made at 12 months' follow-up. METHODS AND ANALYSIS: Pragmatic multicentre cluster randomised controlled clinical trial, single blind with two arms: multifactorial intervention in PHC versus usual follow-up. The randomisation unit is the patient list and the analysis unit is the patient. In addition, a cost-effectiveness study and a qualitative study will be carried out, the latter based on semistructured interviews and focus groups. Two hundred persons (100 per study branch) all aged ≥70 years, presenting frailty, but functionally independent and resident in the community, will be recruited. A baseline evaluation will be carried out prior to the intervention, with follow-up at 6 and 12 months. The main study variables considered will be functional capacity and incidence of adverse events; the secondary variables considered will be the patients' sociodemographic characteristics, nutritional status, level of physical activity and drug consumption, together with data on comorbidity, cognitive and affective status and health-related quality of life. Data will be analysed according to the intention-to-treat principle using a 5% significance level. ETHICS AND DISSEMINATION: The study will at all times be conducted in strict accordance with the provisions of the Declaration of Helsinki and with the national legislation regulating patients' autonomy. All patients recruited will be asked to provide written informed consent before taking part in the clinical trial. On completion of the study, the principal investigator expects to publish the results of this research in a peer-reviewed open access scientific journal. TRIAL REGISTRATION NUMBER: ISRCTN17143761.

Subcutaneous implantable cardioverter-defibrillator in primary and secondary prevention of sudden cardiac death: A meta-analysis.

BACKGROUND: Subcutaneous implantable cardioverter-defibrillator (S-ICD) is gaining in popularity for primary and secondary prevention of sudden cardiac death. The objective was to evaluate the safety and clinical effectiveness of the S-ICD for prevention of sudden cardiac death compared to transvenous cardioverter-defibrillator (TV-ICD). METHODS: A systematic review with meta-analyses was performed. The electronic databases MEDLINE, EMBASE, SCI, and Cochrane Central Register of Controlled Trials were consulted in March 2018 with no restrictions on publication date. Predefined criteria were used to determine inclusion of studies and to assess their methodologic quality. RESULTS: Ten longitudinal-observational studies with comparison group presenting moderate methodologic flaws were included (N = 7820). The combination of results indicates that health-related quality of life is not significantly different between S-ICD and TV-ICD groups (Physical health: MD = 2.90; 95% CI = -3.88, 9.68/Mental health: MD = 0.13; 95% CI = -2.11, 2.37). Mortality occurred in 4.4% of S-ICD patients and 5.9% of TV-ICD patients died (OR = 0.79; 95% CI = 0.50, 1.24). The incidence of infections (OR = 1.79; 95% CI = 0.93, 3.43) and inappropriate shocks (OR = 1.28, 95% CI = 0.91, 1.78) is not significantly different between both groups. The S-ICD reduces complications related to electrodes/leads (OR = 0.13, 95% CI = 0.05, 0.29) and has lower electrodes/leads movement compared with TV-ICD (OR = 0.26; 95% CI 0.10, 0.67). In contrast, pneumothorax is more likely in TV-ICD than S-ICD (OR = 0.17; 95% CI = 0.03, 0.97). CONCLUSIONS: S-ICD reduces electrodes/leads movement, electrodes/leads related complications, and pneumothorax. Our study did not demonstrate a statistically significant difference in mortality, health-related quality of life, and infection rate between S-ICD and TV-ICD.

Validation and comparison of instruments to identify frail patientes in primary care settings: Study protocol.

BACKGROUND: In the last few years several indices and tools, aimed at identifying frail subjects in various care settings have been developed. However, to date none of them has been incorporated into usual practice in the primary care setting. The purposes of this study are: 1) to evaluate the predictive capacity of the Tilburg Frailty Indicator (TFI), the Gérontopôle Frailty Screening Tool (GFST) and the KoS model together with two biomarker levels (SOX2 and p16INK4a) for adverse events related to frailty; 2) to determine differences in the use of healthcare services according to frailty. METHODS/DESIGN: Prospective multicentre cohort study with a 2-year follow-up. The study will be performed in primary care centres of Gipuzkoa and Costa del Sol, both located in Spain. Autonomous, non-institutionalized individuals aged 70 and over that agree to participate in this study will constitute the study population. A total of 900 individuals will be randomly selected from the healthcare administrative data bases of the participating health services. Data will be collected at baseline and at 1 and 2 years. The main independent variables assessed at baseline will be TFI outcomes, GFST and the KoS model, together with the expression of SOX2 and p16INK4a levels. During follow-up, loss of autonomy, the occurrence of death and consumption of healthcare resources will be assessed. DISCUSSION: The main focus of this work is the identification and evaluation of several instruments constructed under different rationales to identify frail subjects in primary care settings. The resulting outcomes have potential for direct application to the primary care practice. Early identification of the onset of functional impairment of elderly is an essential, still unresolved aspect in the prevention of dependence in the scope of primary care.

The utility of heart failure registries: a descriptive and comparative study of two heart failure registries.

BACKGROUND AND AIM: Registries are useful to address questions that are difficult to answer in clinical trials. The objective of this study was to describe and compare two heart failure (HF) cohorts from two Spanish HF registries. METHODS: We compared the RICA and EAHFE registries, both of which are prospective multicentre cohort studies including patients with decompensated HF consecutively admitted to internal medicine wards (RICA) or attending the emergency department (EAHFE). From the latter registry we only included patients who were admitted to internal medicine wards. RESULTS: A total of 5137 patients admitted to internal medicine wards were analysed (RICA: 3287 patients; EAHFE: 1850 patients). Both registries included elderly patients (RICA: mean (SD) age 79 (9) years; EAHFE: mean (SD) age 81 (9) years), with a slight predominance of female gender (52% and 58%, respectively, in the RICA and EAHFE registries) and with a high proportion of patients with preserved ejection fraction (58% and 62%, respectively). Some differences in comorbidities were noted, with diabetes mellitus, dyslipidaemia, chronic renal failure and atrial fibrillation being more frequent in the RICA registry while cognitive and functional impairment predominated in the EAHFE registry. The 30-day mortality after discharge was 3.4% in the RICA registry and 4.8% in the EAHFE registry (p<0.05) and the 30-day readmission rate was 7.5% in the RICA registry (readmission to hospital) and 24.0% in the EAHFE registry (readmission to emergency department) (p<0.001). CONCLUSIONS: We found differences in the clinical characteristics of patients admitted to Spanish internal medicine wards for decompensated HF depending on inclusion in either the RICA or EAHFE registry.

Healthy lifestyle habits for patients with systemic lupus erythematosus: A systemic review.

OBJECTIVES: To assess the effects of lifestyle habits on the disease activity and damage, the occurrence of flares and quality of life of people with systemic lupus erythematosus (SLE). METHODS: A systematic literature review was performed. MEDLINE, EMBASE, and SCI/SSCI were searched. Experimental and observational studies evaluating the effect of lifestyles for SLE patients were included. Two independent reviewers selected studies and extracted relevant data. Critical appraisal of the studies was assessed following SIGN criteria. RESULTS: Eligibility criteria were met by 21 studies, five analyzed the effect of tobacco consumption, nine the effect of physical exercise and seven the effect of diet. Three studies on tobacco observed an association with increased SLE activity and the onset of cutaneous damage. The studies on physical exercise, of heterogeneous quality, reported that aerobic activity is safe for SLE patients, leading to an increase of tolerance to exercise, physical and functional capacity for those with moderate or low activity. A reduction in fatigue, anxiety and depression, as well as improved quality of life, is also suggested though evidence for these outcomes is limited. Better-quality studies on diet analyzed the effect of polyunsaturated fatty acids on disease activity. Three of the four randomized placebo-controlled trials revealed a positive effect both on overall SLE indices and individual symptoms that affect patients. CONCLUSIONS: Tobacco smoking increases the risk of skin damage and disease activity in patients with SLE. A diet rich in polyunsaturated fatty acids, avoiding a sedentary lifestyle and supervised exercise should be recommended for patients with stable SLE.

Factores pronósticos y supervivencia a largo plazo tras el diagnóstico inicial de insuficiencia cardiaca / Prognostic factors and long-term survival after initial diagnosis of heart failure

Fundamento y objetivo: Los objetivos de este estudio fueron evaluar los factores pronósticos y la mortalidad a largo plazo en pacientes con insuficiencia cardiaca (IC) tras su primer diagnóstico, analizar las diferencias en función de la fracción de eyección del ventrículo izquierdo (FEVI) preservada (ICFEP) frente a la disfunción sistólica (ICDS), y, por último, comparar los resultados con los descritos en las principales series de casos incidentes de IC publicadas.Pacientes y método: Estudio de cohortes retrospectivo en el que se incluyeron pacientes con primer ingreso por IC (criterios de Framingham) entre el 1-01-1997 y el 31-12-2001, clasificados en función de la FEVI mayor (ICFEP) o menor (ICDS) del 50%, seguidos durante un período máximo de 10 años. Resultados: Se incluyeron 400 casos incidentes, 231 pacientes (57,7%) tuvieron ICFEP. A los 10 años la mortalidad fue mayor en la ICDS (64,5 frente a 55,4%, p=0,04). Las variables relacionadas con la mortalidad en ICFEP incluyeron edad, diabetes mellitus, cardiopatía isquémica e insuficiencia renal crónica. El tratamiento con estatinas y betabloqueantes se asoció a un mejor pronóstico. En ICDS los predictores de mortalidad fueron similares, aunque las estatinas no mejoraron la supervivencia. Respecto a otras series de casos incidentes, hubo diferencias en cuanto a las variables relacionadas con el pronóstico y la mortalidad de los pacientes. Conclusiones: Tras el diagnóstico inicial de la IC, más de la mitad de los pacientes fallecen a los 10 años de seguimiento. La edad, la diabetes mellitus, la cardiopatía isquémica y la insuficiencia renal crónica se asocian a un peor pronóstico en estos pacientes, mientras que el uso de betabloqueantes se asocia a un mejor pronóstico (AU)

Background and objective: To assess long-term mortality and prognostic factors after initial diagnosis of heart failure (HF), to analyze the differences in function of the left ventricular ejection fraction (preserved [HFPEF] vs. systolic dysfunction [HFSD]) and to compare the results with the main series of incident cases of HF published.Patients and methods: Retrospective cohort study including patients first diagnosed of heart failure (Framingham criteria), between 1-01-1997 and 31-12-2001, classified according to a left ventricle ejection fraction (LVEF) above or equal to 50% (HFPEF) or below 50% (HFSD). Follow-up of patients was conducted during ten years.Results: Out of 400 incident cases of heart failure, 231 patients (57,7%) presented with HFPEF. At 10 years, mortality rates were higher in the HFSD group (64,5 vs. 55,4%, p=0,04). Following a multi-variant analysis, HFPEF mortality was related with age, diabetes mellitus, ischemic heart disease, and chronic renal failure. Treatment with statins and beta-blockers was associated with improved prognosis. Among patients with HFSD, mortality predictors were similar, although patients treated with statins did not show higher survival rates. For other series of incident cases, there were differences in variables related to prognosis and mortality of patients. Conclusions: After an initial diagnosis of HF, more than half of patients die within 10 years of monitoring. Age, diabetes mellitus, ischemic heart disease and chronic renal failure are all associated with worse prognosis in these patients, whereas the use of beta-blockers and statins is associated with a better prognosis (AU)

CONCLUSIONS: After an initial diagnosis of HF, more than half of patients die within 10 years of monitoring. Age, diabetes mellitus, ischemic heart disease and chronic renal failure are all associated with worse prognosis in these patients, whereas the use of beta-blockers and statins is associated with a better prognosis.
