Aims: There is a lack of specific studies assessing the impact of natriuretic peptide monitoring in the post-discharge management of patients with heart failure (HF) and preserved ejection fraction (HFpEF), throughout the vulnerable phase following acute HF hospitalization. The NICE study aims to assess the clinical benefit of incorporating N-terminal pro-B-type natriuretic peptide (NT-proBNP) into the post-discharge management of HFpEF patients.

Methods And Results: Individuals admitted with HFpEF (left ventricular ejection fraction >50%) were included in a multicentre randomized controlled study employing an open-label design with event blinding (NCT02807168).

Introduction And Objectives: The tricuspid annular plane systolic excursion/systolic pulmonary artery pressure (TAPSE/SPAP) ratio is a noninvasive surrogate of right ventricular to pulmonary circulation that has prognostic implications in patients with heart failure (HF) or pulmonary hypertension. Our purpose was to evaluate the prognostic value of the TAPSE/SPAP ratio in patients with cardiac amyloidosis.

Methods: We used the database of the AMIGAL study, a prospective, observational registry of patients with cardiac amyloidosis recruited in 7 hospitals of the Autonomous Community of Galicia, Spain, from January 1, 2018 to October 31, 2022.

Background: We aimed to describe the clinical characteristics, underlying causes and outcomes of syncope in patients with transthyretin amyloid cardiomyopathy (ATTR-CM).

Methods: The clinical profile and underlying causes of syncopal episodes were reviewed in a cohort of 128 patients with ATTR-CM enrolled from January 2018 to June 2020 in a prospective multicentre registry in 7 hospitals of Galicia (Spain). After enrollment, patients were followed during a median period of 520 days.

Inflammation is one of the mechanisms involved in heart failure (HF) pathophysiology. Thus, the acute phase reactant protein, orosomucoid, was associated with a worse post-discharge prognosis in acute HF (AHF). However, the presence of anti-inflammatory adipokine, omentin, might protect and reduce the severity of the disease.

Objective: To investigate a potential association between beta-blocker exposure and survival in patients with transthyretin amyloid cardiomyopathy (ATTR-CM).

Methods: In this real-world prospective registry of 128 consecutive patients with ATTR-CM recruited in 7 institutions in Galicia (Spain), survival of 65 patients who received beta blockers on registry enrollment was compared with that of 63 untreated controls by means of both unweighted Cox regression and Cox regression with inverse probability of treatment weighting. Tolerance to and adverse effects of beta blockers were recorded.

Article Synopsis
  • The study aimed to compare soluble angiotensin-converting enzyme-2 (sACE2) plasma level variations and their impact on the prognosis of two groups: heart failure (HF) and acute coronary syndrome (ACS).
  • In a clinical study involving 102 patients from each cohort, higher levels of sACE2 were found in the HF group, and these levels were linked to long-term cardiac outcomes and various health parameters, depending on the cohort.
  • Treatment with angiotensin receptor blockers and β-blockers was associated with increased sACE2 levels, indicating that certain cardiovascular drugs influence ACE enzymes, with implications for patient management in HF and ACS.

Background: Healthcare systems are under prominent stress due to the COVID-19 pandemic. A fast and simple triage is mandatory to screen patients who will benefit from early hospitalization, from those that can be managed as outpatients. There is a lack of all-comers scores, and no score has been proposed for western-world population.

Article Synopsis
  • COVID-19 is a global pandemic, and researchers aimed to understand if prior use of ACE inhibitors (ACEI) or angiotensin receptor blockers (ARB) affects the outcomes for patients diagnosed with the virus.
  • A retrospective study of nearly 1,000 COVID-19 patients found that those on ACEI/ARB drugs showed no significant differences in mortality, hospitalization, or severe cardiovascular events.
  • The study concludes that continuing ACEI/ARB treatment in COVID-19 patients is supported by existing guidelines, as it doesn't negatively impact their health outcomes.

Introduction And Objectives: Coronavirus disease (COVID-19) has been designated a global pandemic by the World Health Organization. It is unclear whether previous treatment with angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) affects the prognosis of COVID-19 patients. The aim of this study was to evaluate the clinical implications of previous treatment with ACEI/ARB on the prognosis of patients with COVID-19 infection.

Introduction And Objectives: Beta-blockers, angiotensin-converting enzyme inhibitors (ACE inhibitors), angiotensin-II-receptor-blockers (ARB), and mineralocorticoid-receptor antagonists decrease mortality and heart failure (HF) hospitalizations in HF patients with reduced left ventricular ejection fraction. The effect is dose-dependent. Careful titration is recommended.

Introduction And Objectives: Hyperkalemia is a growing concern in the treatment of patients with heart failure and reduced ejection fraction because it limits the use of effective drugs. We report estimates of the magnitude of this problem in routine clinical practice in Spain, as well as changes in potassium levels during follow-up and associated factors.

Methods: This study included patients with acute (n=881) or chronic (n=3587) heart failure recruited in 28 Spanish hospitals of the European heart failure registry of the European Society of Cardiology and followed up for 1 year.

Aims: This work aimed to compare the behavior of the advanced glycation end products (AGEs) and their soluble receptor (sRAGE) in two cohorts of patients: those with heart failure (HF) and acute coronary syndrome (ACS).

Methods And Results: A unicentric observational clinical study was performed in 102 patients with ACS and 102 patients with chronic HF matched by age and gender. At inclusion, fluorescent AGEs were measured by quantitative fluorescence spectroscopy of plasma, and total sRAGE and endogenous secretory RAGE (esRAGE) levels were determined by enzyme-linked immunosorbent assay kits.

Objectives: Characterization of the type of glycation found in circulating proteins from cardiovascular patients in comparison with healthy control subjects and to explore the pathophysiological molecular effects of these glycomodified proteins on human umbilical vein endothelial cells (HUVEC) in culture.

Methods: Human serum albumin pools from 10 subjects each, of patients with heart failure (HF) presenting high or low glycation levels, and from healthy subjects were isolated and purified. The glycation levels of these pools were characterized by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and compared between them.

Introduction: Today's healthcare policies rely heavily on data that has been gathered from multiple small studies in intrinsically varied populations. We sought to describe the prevalence, comorbidities and outcomes of atrial fibrillation (AF) in the population of a specific region where all healthcare centers have implemented a common information technology (IT) structure.

Methods: The total number of inhabitants was obtained from the healthcare area's IT system.

A obesity paradox has been described following heart failure (HF). The aim of this study was to analyze the association between food intake-involved adipokines and long-term weight changes. Leptin, adiponectin, and omentin were analyzed in 92 acute HF (AHF) patients at discharge, classified on the basis of weight gains or losses > 6%.

Hyperadiponectinemia is an indicator of worse outcomes in advanced heart failure (HF), its role in HF is less clear. Because this protein is a hormone with starvation properties, we wanted to know its association with nutritional state and its regulator factors in HF. Adiponectin circulating levels were determined by ELISA at discharge in patients admitted for HF (n=74).

Introduction And Objectives: Contemporary data on the incidence and prognosis of heart failure (HF) and the influence of left ventricular ejection fraction (LVEF) in the setting of acute coronary syndrome (ACS) are scant. The aim of this study was to examine the relationship between LVEF and HF with long-term prognosis in a cohort of patients with ACS.

Methods: This is a retrospective observational study of 6208 patients consecutively admitted for ACS to 2 different Spanish hospitals.
