Clinical suspicion, diagnosis and management of cardiac amyloidosis: update document and executive summary.

In recent years, the interest in cardiac amyloidosis has grown exponentially. However, there is a need to improve our understanding of amyloidosis in order to optimise early detection systems. Therefore, it is crucial to incorporate solutions to improve the suspicion, diagnosis and follow-up of cardiac amyloidosis. In this sense, we designed a tool following the different phases to reach the diagnosis of cardiac amyloidosis, as well as an optimal follow-up: a) clinical suspicion, where the importance of the "red flags" to suspect it and activate the diagnostic process is highlighted; 2) diagnosis, where the diagnostic algorithm is mainly outlined; and 3) follow-up of confirmed patients. This is a practical resource that will be of great use to all professionals caring for patients with suspected or confirmed cardiac amyloidosis, to improve its early detection, as well as to optimise its accurate diagnosis and optimal follow-up.

Sex differences in clinical characteristics and outcomes in the CLOROTIC (combining loop with thiazide diuretics for decompensated heart failure) trial.

AIMS: The addition of hydrochlorothiazide (HCTZ) to furosemide improved the diuretic response in patients with acute heart failure (AHF) in the CLOROTIC trial. Our aim was to evaluate if there were differences in clinical characteristics and outcomes according to sex. METHODS: This is a post-hoc analysis of the CLOROTIC trial, including 230 patients with AHF randomized to receive HCTZ or placebo in addition to an intravenous furosemide regimen. The primary and secondary outcomes included changes in weight and patient-reported dyspnoea 72 and 96 h after randomization, metrics of diuretic response and mortality/rehospitalizations at 30 and 90 days. The influence of sex on primary, secondary and safety outcomes was evaluated. RESULTS: One hundred and eleven (48%) women were included in the study. Women were older and had higher values of left ventricular ejection fraction. Men had more ischemic cardiomyopathy and chronic obstructive pulmonary disease and higher values of natriuretic peptides. The addition of HCTZ to furosemide was associated to a greatest weight loss at 72/96 h, better metrics of diuretic response and higher 24-h diuresis compared to placebo without significant differences according to sex (all p-values for interaction were not significant). Worsening renal function occurred more frequently in women (OR [95%CI]: 8.68 [3.41-24.63]) than men (OR [95%CI]: 2.5 [0.99-4.87]), p = 0.027. There were no differences in mortality or rehospitalizations at 30/90 days. CONCLUSION: Adding HCTZ to intravenous furosemide is an effective strategy to improve diuretic response in AHF with no difference according to sex, but worsening renal function was more frequent in women. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov: NCT01647932; EudraCT Number: 2013-001852-36.

Executive summary of the 2023 update on the consensus regarding basic conduct during hospital admission for patients with acute heart failure.

Acute heart failure (AHF) is associated with significant morbidity and mortality and it stands as the primary cause of hospitalization for individuals over the age of 65 in Spain. This document outlines the main recommendations as follows: (1) Upon admission, it is crucial to conduct a comprehensive assessment, taking into account the patient's standard treatment and comorbidities, as these factors determine the prognosis of the disease. (2) During the initial hours of hospital care, prioritizing decongestive treatment is essential. It is recommended to adopt an early staged diuretic therapeutic approach based on the patient's response. (3) In order to manage patients in the stable phase, it is advisable to consider initiating and/or adjusting evidence-based drug treatments such as sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta blockers, aldosterone antagonists, and SGLT2 inhibitors. (4) Upon hospital discharge, utilizing a checklist is recommended to optimize the patient's management and identify the most efficient options for ensuring continuity of care post-discharge.

Current heart failure disease management and treatment in accredited units from cardiology and internal medicine in Spain.

BACKGROUND AND OBJECTIVES: Heart failure (HF) is a complex disease with high prevalence, incidence and mortality rates leading to high healthcare burden. In Spain, there are multidisciplinary HF units coordinated by cardiology and internal medicine. Our objective is to describe its current organizational model and their adherence to the latest scientific recommendations. MATERIALS AND METHODS: In late 2021, a scientific committee (with cardiology and internal medicine specialists) developed a questionnaire that was sent as an online survey to 110 HF units. 73 from cardiology (accredited by SEC-Excelente) and 37 from internal medicine, (integrated in UMIPIC program). RESULTS: We received 83 answers (75.5% total: 49 from cardiology and 34 from internal medicine). The results showed that HF units are mostly integrated by specialists from cardiology, internal medicine and specialized nurse practitioners (34.9%). Patient characteristics from HF units are widely different when comparing those in cardiology to UMIPIC, being the latter older, more frequently with preserved ejection fraction and higher comorbidity burden. Most HF units (73.5%) currently use a hybrid face-to-face/virtual model to perform patient follow-up. Natriuretic peptides are the biomarkers most commonly used (90%). All four disease-modifying drug classes are mainly implemented at the same time (85%). Only 24% of HF units hold fluent communication with primary care. CONCLUSIONS: Both models from cardiology and internal medicine HF units are complementary, they include specialized nursing, they use hybrid approach for patient follow-up and they display a high adherence to the latest guideline recommendations. Coordination with primary care remains as the major improvement area.

Vericiguat in heart failure: From scientific evidence to clinical practice.

Despite currently available treatments, risk of death and hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF) remains high. The pathophysiology of HFrEF includes neurohormonal activation characterized by stimulation of deleterious pathways (i.e., sympathetic nervous and renin-angiotensin-aldosterone systems) and suppression of protective pathways such as nitric oxide-dependent pathways. Inhibition or stimulation of some, but not all, of these pathways is insufficient. In HFrEF, there is reduced nitric oxide, soluble guanylate cyclase, and cGMP activity, leading to deleterious effects in the myocardial, vascular, and renal systems. Vericiguat is able to stimulate the activity of this protective pathway. The VICTORIA study demonstrated that the addition of vericiguat to optimal medical treatment in patients with HFrEF and recent decompensation significantly reduced the incidence of the primary endpoint, a composite of cardiovascular death or HF hospitalization, with a number needed to treat of 24 patients and excellent tolerability.

Benefits of a comprehensive care model in patients with heart failure and preserved ejection fraction: The UMIPIC program.

BACKGROUND: Patients with heart failure (HF) and preserved ejection fraction (HFpEF), in contrast to those with reduced ejection fraction, are older, have more comorbidities, and are not candidates for effective therapeutic measures. Therefore, they are at high risk for hospital admission and mortality. This study evaluated the benefit of a comprehensive continuous care program (UMIPIC program) in patients with HFpEF. METHODS: We prospectively analyzed data on 2401 patients with HFpEF attended to in internal medicine departments who form part of the RICA registry. They were divided into 2 groups: one was followed-up on in the UMIPIC program (UMIPIC group, n: 1011) and another received conventional care (RICA group, n: 1390). A total of 753 patients in each group were selected by propensity score matching and admissions and mortality were assessed during 12 months of follow-up after an episode of hospitalization due to HF. RESULTS: Compared to the RICA group, the UMIPIC group had a lower rate of HF admissions (19.2% versus 36.5%, respectively; hazard ratio [HR] = 0.56; 95% confidence interval [CI]: 0.45-0.68; p < 0.001) and mortality (12.6% versus 28%, respectively; HR = 0.40; 95% CI: 0.31-0.51; p < 0.001). There were no differences in hospitalizations for non-HF causes. CONCLUSIONS: Implementation of the UMIPIC program, which is based on comprehensive continuous care, for patients with HFpEF and a high degree of comorbidity reduces both admissions and mortality in the first year of follow-up.

Morbidity and mortality in elderly patients with heart failure managed with a comprehensive care model vs. usual care: The UMIPIC program.

BACKGROUND: Elderly patients with heart failure (HF) have a high degree of comorbidity which leads to fragmented care, with frequent hospitalizations and high mortality. This study evaluated the benefit of a comprehensive continuous care model (UMIPIC program) in elderly HF patients. METHODS AND RESULTS: We prospectively analyzed data from the RICA registry on 2862 patients with HF treated in internal medicine departments. They were divided into two groups: one monitored in the UMIPIC program (UMIPIC group, n: 809) and another which received conventional care (RICA group, n: 2.053). We evaluated HF readmissions during 12 months of follow-up and total mortality after episodes of HF hospitalization. UMIPIC patients were older with higher rates of comorbidity and preserved ejection fraction than the RICA group. However, the UMIPIC group had a lower rate of HF readmissions (17% vs. 26%, p < .001) and mortality (16% vs. 27%, respectively; p < .001). In addition, we selected 370 propensity score-matched patients from each group and the differences in HF readmissions (15% UMIPIC vs. 30% RICA; hazard ratio [HR] = 0.44; 95% confidence interval [CI] 0.32-0.60; p < .001) and mortality (17% UMIPIC vs. 28% RICA; hazard ratio = 0.58; 95% CI 0.42-0.79; p = .001) were maintained. CONCLUSIONS: The implementation of the UMIPIC program, based on comprehensive continuous care of elderly patients with HF and high comorbidity, markedly reduce HF readmissions and total mortality.

Prognostic value of ambulatory blood pressure values in elderly patients with heart failure. Results of the DICUMAP study.

INTRODUCTION: Ambulatory blood pressure monitoring (ABPM) has demonstrated value in the prognostic assessment of hypertensive patients with heart failure (HF) with or without other cardiovascular diseases. The objective of this study was to evaluate whether ABPM can identify subjects with HF with a worse prognosis. METHODS AND RESULTS: Prospective multicenter study that included clinically stable outpatients with HF. All patients underwent ABPM. A total of 154 patients from 17 centers were included. Their mean age was 76.8 years (± 8.3) and 55.2% were female. In total, 23.7% had HF with a reduced ejection fraction (HFrEF), 68.2% were in NYHA functional class II, and 19.5% were in NYHA functional class III. At one year of follow up, there were 13 (8.4%) deaths, of which 10 were attributed to HF. Twenty-nine patients required hospitalization, of which 19 were due to HF. The presence of a non-dipper BP pattern was associated with an increased risk for readmission or death at one year of follow-up (25% vs. 5%; p=.024). According to a Cox regression analysis, more advanced NYHA functional class (hazard ratio 3.51; 95% CI 1.70-7.26; p=.001; for NYHA class III vs. II) and a higher proportional nocturnal reduction in diastolic BP (hazard ratio 0.961; 95%CI 0.926-0.997; p=.032 per 1% diastolic BP reduction) were independently associated with death or readmission at one year. CONCLUSION: In older patients with chronic HF, a non-dipper BP pattern measured by ABPM was associated with a higher risk of hospitalization and death due to HF.

Consensus on improving the comprehensive care of patients with acute heart failure.

The latest acute heart failure (AHF) consensus document from the Spanish Society of Cardiology (SEC, for its initials in Spanish), Spanish Society of Internal Medicine (SEMI), and Spanish Society of Emergency Medicine (SEMES) was published in 2015, which made an update covering the main novelties regarding AHF from the last few years necessary. These include publication of updated European guidelines on HF in 2016, new studies on the pharmacological treatment of patients during hospitalization, and other recent developments regarding AHF such as early treatment, intermittent treatment, advanced HF, and refractory congestion. This consensus document was drafted with the aim of updating all aspects related to AHF and to create a document that comprehensively describes the diagnosis, treatment, and management of this disease.

Consensus on basic conduct during the hospital admission of patients with acute heart failure.

Acute heart failure (AHF) is a highly prevalent clinical entity in individuals older than 45 years in Spain. AHF is associated with significant morbidity and mortality and is the leading cause of hospitalisation for individuals older than 65 years in Spain, a quarter of whom die within 1 year of the hospitalisation. In recent years, there has been an upwards trend in hospitalisations for AHF, which increased 76.7% from 2003 to 2013. Readmissions at 30 days for AHF have also increased (from 17.6% to 22.1%), at a relative mean rate of 1.36% per year, with the consequent increase in the use of resources and the economic burden for the healthcare system. The aim of this document (developed by the Heart Failure and Atrial Fibrillation Group of the Spanish Society of Internal Medicine) is to guide specialists on the most important aspects of treatment and follow-up for patients with AHF during hospitalisation and the subsequent follow-up. The main recommendations listed in this document are as follows: 1) At admission, perform a comprehensive assessment, considering the patient's standard treatment and comorbidities, given that these determine the disease prognosis to a considerable measure. 2) During the first few hours of hospital care, decongestive treatment is a priority, and a staged diuretic therapeutic approach based on the patient's response is recommended. 3) To manage patients in the stable phase, consider starting and/or adjusting evidence-based drug treatment (e.g., sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta blockers and aldosterone antagonists). 4) At hospital discharge, use a checklist to optimise the patient's management and identify the most efficient options for maintaining continuity of care after discharge.

The short-term prognostic value of C-reactive protein in elderly patients with acute heart failure. / Valor pronóstico a corto plazo de la proteína C reactiva en ancianos con insuficiencia cardíaca aguda.

INTRODUCTION AND OBJECTIVES: Plasma c-reactive protein (crp) has been tested as a prognostic marker in acute heart failure (ahf). Whether its measurement really provides significant prognostic information when applied to elderly patients with ahf episodes remains unclear. METHODS: We measured the plasma crp values of patients admitted because of any type of ahf to internal medicine services. We evaluated the association of these values with the patients' baseline clinical characteristics and their 3-month posdischarge all-cause mortality or readmission rates. For comparison purposes, we divided the sample in tertiles of low, medium and high crp values (<2,24mg/l, 2,25-11,8mg/l and>11,8mg/l). RESULTS: We included 1443 patients with a median age of 80 years (interquartile range 73-85); 680 (47%) were men, with a moderate comorbid burden. 60.1% had preserved left ventricular ejection fraction (> 50%). Multivariate analysis confirmed an independent association between higher crp values and the presence of respiratory infection, lower systolic blood pressure and deteriorated renal function upon admission. Three months after the index admission, a total of 142 patients (9.8%) had died, and 268 (18.6%) had either been readmitted or died. admission crp values did not correlate with 3-month all-cause mortality (P=0.79), 3-month all-cause readmission (P=0.96) or the combination of both events (P=0.96). However, higher crp values were associated with a longer length of stay (P<0.001). CONCLUSION: Our study does not confirm an association between admission plasma crp values in elderly ahf patients and subsequent higher 3-month mortality or readmission risks.

Hyponatraemia and congestive heart failure refractory to diuretic treatment. Utility of tolvaptan. / Hiponatremia e insuficiencia cardiaca congestiva refractaria a tratamiento diurético. Utilidad del tolvaptán.

Heart failure (HF) is currently one of the most significant healthcare problems in Spain and has a continuously increasing prevalence. Advances in our understanding of the various biological responses that promote cardiac remodelling and pulmonary venous congestion constitute the basis of current treatment. This article, prepared by members of the HF groups of the Spanish Society of Cardiology and the Spanish Society of Internal Medicine, discusses the current therapeutic strategies for patients with congestion refractory to diuretic treatment. The article includes our clinical experience with the use of tolvaptan as an additional treatment for congestion associated with hyponatraemia. To this end, we propose an algorithm for the use of tolvaptan in patients with congestive HF, natraemia <130mEq/l and poor response to conventional diuretic treatment.

Consensus Document of the Spanish Society of Cardiology and the Spanish Society of Internal Medicine on the diagnosis and treatment of iron deficiency in heart failure. / Documento de consenso de la Sociedad Española de Cardiología y la Sociedad Española de Medicina Interna sobre el diagnóstico y tratamiento del déficit de hierro en la insuficiencia cardíaca.

Iron deficiency in patients with heart failure is a medical problem of recent particular interest. This interest has resulted from the publication of several clinical trials that demonstrated that the administration of intravenous iron to such patients improved their functional capacity and even reduced the number of hospitalisations for heart failure decompensation. However, applying the evidence from these studies in clinical practice is still controversial, both in terms of the diagnostic criteria for iron deficiency (absolute and functional) and the optimal method for iron replenishment. This article is a consensus document that integrates the recommendations of the Spanish Society of Internal Medicine and the Spanish Society of Cardiology. The article reviews the scientific evidence and proposes a diagnostic and therapeutic performance protocol for iron deficiency in heart failure.
