Background: Hypertrophic cardiomyopathy (HCM) is an inherited disorder whose causal variants involve sarcomeric protein genes. One of these is myosin-binding protein C (MYBPC3), being previously associated with a favourable prognosis. Our objective is to describe the clinical characteristics and events of a molecularly homogeneous HCM cohort associated with truncating variants.

Article Synopsis
  • Most signs and symptoms of heart failure stem from fluid overload, which complicates both diagnosis and treatment as it relates to disease progression.
  • Effective management requires a multiparametric approach that incorporates clinical data, imaging tests, and biomarkers.
  • The article, produced by Spanish medical societies, suggests practical strategies for treating hydrosaline overload in heart failure for patients in both inpatient and outpatient settings.

Article Synopsis
  • The study investigates the risk factors for hospitalization due to heart failure (HF) in patients with acute coronary syndrome (ACS) who have not previously experienced HF or left ventricular dysfunction.
  • It analyzed data from 14,699 patients across 16 European centers using both Cox regression and machine learning models, identifying key risk factors such as reduced renal function and left ventricular ejection fraction.
  • The CORALYS HF score successfully pinpointed high-risk patients using commonly available information at discharge, indicating a need for further strategies to prevent HF in this specific group.

Background The impact of complete revascularization (CR) on the development of heart failure (HF) in patients with acute coronary syndrome and multivessel coronary artery disease undergoing percutaneous coronary intervention remains to be elucidated. Methods and Results Consecutive patients with acute coronary syndrome with multivessel coronary artery disease from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of first hospitalization for HF or cardiovascular death was the primary end point.

Introduction And Objectives: Atrial fibrillation (AF) is linked to heart failure (HF). However, little has been published on the factors that may precipitate the onset of HF in AF patients. We aimed to determine the incidence, predictors, and prognosis of incident HF in older patients with AF with no prior history of HF.

Background: Medical treatment in Heart Failure (HF) with reduced ejection fraction (HFrEF; LVEF ≤40%) has shifted towards quadruple therapy. Maximum tolerated dose is the goal, yet no hypotension's cut-off point has been specified. In this work, we analyze the impact of intensive drug titration in clinical events, focusing on low blood pressure (BP) patients at hospital discharge.

Advanced heart failure is a growing problem for which the best treatment is cardiac transplantation. However, the shortage of donors' hearts made left ventricular assist devices as destination therapy (DT-LVAD) a highly recommended alternative: they improved mid-term prognosis as well as patients' quality of life. Current intracorporeal pumps with a centrifugal continuous flow evolved in the last few years.

(1) Background: Pulmonary endarterectomy (PEA) is the "gold standard" treatment for operable patients with chronic thromboembolic pulmonary hypertension (CTEPH). Persistent pulmonary hypertension (PH) after PEA confers a worse prognosis. Balloon pulmonary angioplasty (BPA) could represent a useful therapy in this setting, but evidence about its effectiveness and safety in patients with previous PEA is limited.

Aim: Patients with advanced heart failure (AHF) who are not candidates to advanced therapies have poor prognosis. Some trials have shown that intermittent levosimendan can reduce HF hospitalizations in AHF in the short term. In this real-life registry, we describe the patterns of use, safety and factors related to the response to intermittent levosimendan infusions in AHF patients not candidates to advanced therapies.

Article Synopsis
  • The study aimed to determine how cancer affects the risks of embolic (blood clots) and bleeding events in patients with atrial fibrillation (AF).
  • In a cohort of over 16,000 AF patients, only those with active cancer or a history of radiotherapy showed a higher risk of bleeding, but there was no increased risk of embolic events due to cancer.
  • The widely used CHADS-VASc and HAS-BLED scores were found to be less effective at predicting risks in nonanticoagulated patients with active cancer.

Background: Previous studies investigating predictors of Heart Failure (HF) after acute coronary syndrome (ACS) were mostly conducted during fibrinolytic era or restricted to baseline characteristics and diagnoses prior to admission. We assessed the incidence and predictors of HF hospitalizations among patients treated with percutaneous coronary intervention (PCI) for ACS.

Methods And Results: CORALYS is a multicenter, retrospective, observational registry including consecutive patients treated with PCI for ACS.

Little is known about the prediction of atrial fibrillation (AF) risk scores in patients with cancer. The aim of this study was to assess the predictive ability of the CHADS-VASc and HAS-BLED scores in patients with AF and cancer. Overall, 16,056 patients with AF diagnosed between 2014 and 2018 from a Spanish health area, including 1,137 patients with cancer, were observed during a median follow-up of 4.

Introduction And Objectives: A paradoxical protective effect of obesity has been previously reported in patients with atrial fibrillation (AF). The aim of this study was to determine the impact of nutritional status and body mass index (BMI) on the prognosis of AF patients.

Methods: We conducted a retrospective population-based cohort study of patients with AF from 2014 to 2017 from a single health area in Spain.

Acute idiopathic pericarditis (AIP) is a benign inflammatory condition associated with high recurrence rates. Non-steroidal anti-inflammatory drug (NSAIDs) and colchicine are the recommended therapies. Our objective was to systematically assess effects of pharmacological therapies on recurrences or treatment failure in patients with first and subsequent AIP episodes.

Despite patients with cancer having a higher incidence of atrial fibrillation (AF), little is known about the predictors of outcomes in this population. This study aimed to assess the incidence and predictors of bleeding in patients with AF and cancer. The study population comprised 16,056 patients from a Spanish health area diagnosed with AF between 2014 and 2018 (1,137 with cancer).

Background: The association between digoxin and mortality is an unclear issue. In older patients with atrial fibrillation (AF), where use of digoxin is frequent, the evidence of its safety is scarce. Our aim is to assess the safety of digoxin in nonagenarian patients with AF.

Aims: Despite aortic stenosis (AS) relief, patients undergoing transcatheter aortic valve implantation (TAVI) are at increased risk of developing heart failure (HF) within first months of intervention. Sodium-glucose co-transporter 2 (SGLT-2) inhibitors have been shown to reduce the risk of HF hospitalization in individuals with diabetes mellitus, reduced left ventricular ejection fraction and chronic kidney disease. However, the effect of SGLT-2 inhibitors on outcomes after TAVI is unknown.

Article Synopsis
  • The study investigates how truncating TTN variants (TTNtv) lead to dilated cardiomyopathy (DCM) by examining electrocardiograms (ECGs) and echocardiograms of TTNtv-DCM patients and their relatives.
  • Patients were categorized into five groups based on their left ventricular ejection fraction (LVEF), recovery status, and genetic factors, with analyses showing significant differences in T-index and abnormal T-wave prevalence among these groups.
  • The findings suggest that changes in repolarization patterns in ECGs can help identify patients with varying responses to treatment and highlight those at higher risk within the TTNtv-DCM spectrum.

Introduction And Objectives: The recent Academic Research Consortium for High Bleeding Risk (ARC-HBR) proposal did not consider acute coronary syndrome (ACS), by consensus, a bleeding criterion per se despite being a high bleeding risk (HBR) scenario. We investigated the applicability of the ARC-HBR classification and criteria in ACS patients.

Methods: Patients with ACS undergoing coronary stenting between 2012 and 2018 at a tertiary hospital were retrospectively classified as being at HBR if they met ≥ 1 major or ≥ 2 minor ARC-HBR criteria.
