Quantifying the Survival Loss Linked to Late Therapeutic Indication in High-Gradient Severe Aortic Stenosis.

Background: International guidelines recommend aortic valve replacement (AVR) as Class I triggers in high-gradient severe aortic stenosis (HGSAS) patients with symptoms and/or left ventricular ejection fraction (LVEF) <50%. The association between waiting for these triggers and postoperative survival penalty is poorly studied.

Objectives: The purpose of this study was to examine the impact of guideline-based Class I triggers on long-term postoperative survival in HGSAS patients.

Carbohydrate antigen 125: a useful marker of congestion, fibrosis, and prognosis in heart failure with preserved ejection fraction.

Aims: Heart failure (HF) with preserved ejection fraction (HFpEF) is a disease associated with high morbidity and mortality, for which it is difficult to identify patients with the poorest prognosis in routine clinical practice. Carbohydrate antigen 125 (CA 125) has been shown to be a potential marker of congestion and prognosis in HF. We sought to better characterize HFpEF patients with high CA 125 levels by using a multimodal approach.

Cardiac structure, function, and coronary anatomy 10 years after isolated contemporary adjuvant radiotherapy in breast cancer patients with low cardiovascular baseline risk.

Aims: The effects of isolated contemporary low-dose breast cancer (BC) radiotherapy (RT) on the heart remain poorly understood. This study aims to assess the long-term impacts of BC-RT on cardiac structure and function.

Methods And Results: Seventy-six women (62 ± 7 years) without history of prior heart disease, who had undergone RT for either first left (n = 36) or right (n = 40) BC, without additional medical oncology therapy apart from hormonal treatment 11 ± 1 years earlier, underwent transthoracic echocardiography, cardiac magnetic resonance imaging (CMR), computed tomography coronary angiography (CTCA), NT-proBNP, and a 6-min walk test (6MWT).

Repurposing the β3-Adrenergic Receptor Agonist Mirabegron in Patients With Structural Cardiac Disease: The Beta3-LVH Phase 2b Randomized Clinical Trial.

Importance: Left ventricular (LV) hypertrophy contributes to the onset and progression of heart failure (HF), particularly for patients with pre-HF (stage B) for whom no treatment has yet proven effective to prevent transition to overt HF (stage C). The β3-adrenergic receptors (β3ARs) may represent a new target, as their activation attenuates LV remodeling.

Objective: To determine whether activation of β3ARs by repurposing a β3AR agonist, mirabegron, is safe and effective in preventing progression of LV hypertrophy and diastolic dysfunction among patients with pre- or mild HF.

Dual antiplatelet therapy is associated with high α-tubulin acetylation in circulating platelets from coronary artery disease patients.

Platelet inhibition is the main treatment strategy to prevent atherothrombotic complications after acute coronary syndrome or percutaneous coronary intervention. Despite dual antiplatelet therapy (DAPT) combining aspirin and a P2Y receptor inhibitor, high on-treatment platelet reactivity (HPR) persists in some patients due to poor response to treatment and is associated with ischemic risk. Tubulin acetylation has been pointed out as a hallmark of stable microtubules responsible for the discoid shape of resting platelets.

CA125, Galectin-3 and FGF-23 are interrelated in heart failure with reduced ejection fraction.

Background: Carbohydrate Antigen 125 (CA125) is the most widely used biomarker in ovarian cancer screening. In patients with heart failure (HF), increased levels of CA125 have been observed and related to disease severity. Our objective was to determine the association of CA125 levels with two biomarkers of adverse remodeling in HF patients with reduced ejection fraction (HFrEF).

Prognostic Implications of Discordant Low-Gradient Severe Aortic Stenosis: Comprehensive Analysis of a Large Multicenter Registry.

Background: Up to 30% of patients with severe aortic stenosis (SAS) (indexed aortic valve area [AVAi] <0.6 cm/m) exhibit low-transvalvular gradient despite normal ejection fraction. There is intense debate regarding the prognostic significance of this entity.

Association of Plasma Myeloperoxidase with Inflammation and Diabetic status in HFpEF.

Background: Inflammation and oxidative stress are thought to play an important role in the pathophysiology of heart failure with preserved ejection fraction (HFpEF) through the development of endothelial dysfunction. Myeloperoxidase (MPO) functions as a link between oxidative stress and inflammation and is an interesting therapeutic target. The objective of this observational cohort study was to compare MPO levels between HFpEF and old controls, to define clinical characteristics associated with high levels of MPO and to assess the relation between MPO levels and vascular function.

Sex-related differences in left ventricular assist device utilization and outcomes: results from the PCHF-VAD registry.

Aims: Data on sex and left ventricular assist device (LVAD) utilization and outcomes have been conflicting and mostly confined to US studies incorporating older devices. This study aimed to investigate sex-related differences in LVAD utilization and outcomes in a contemporary European LVAD cohort.

Methods And Results: This analysis is part of the multicentre PCHF-VAD registry studying continuous-flow LVAD patients.

Partial anomalous pulmonary venous return in adults: Insight into pulmonary hypertension.

Background: Partial anomalous pulmonary venous return (PAPVR) is a rare condition that may lead to pulmonary arterial hypertension (PAH). We sought to determine the prevalence of PAPVR, the follow-up rate of incidentally discovered PAPVR, the repercussions of volume and pressure overload on the right ventricle (RV), and the prevalence and predictors of PAH.

Methods And Results: Fifty PAPVR patients aged ≥18 years were included.

Impact of progressive aortic regurgitation on outcomes after left ventricular assist device implantation.

Aortic regurgitation (AR) following continuous flow left ventricular assist device implantation (cf-LVAD) may adversely impact outcomes. We aimed to assess the incidence and impact of progressive AR after cf-LVAD on prognosis, biomarkers, functional capacity and echocardiographic findings. In an analysis of the PCHF-VAD database encompassing 12 European heart failure centers, patients were dichotomized according to the progression of AR following LVAD implantation.

Acetazolamide in Decompensated Heart Failure with Volume Overload trial (ADVOR): baseline characteristics.

Aims: To describe the baseline characteristics of participants in the Acetazolamide in Decompensated Heart Failure with Volume Overload (ADVOR) trial and compare these with other contemporary diuretic trials in acute heart failure (AHF).

Methods And Results: ADVOR recruited 519 patients with AHF, clinically evident volume overload, elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) and maintenance loop diuretic therapy prior to admission. All participants received standardized loop diuretics and were randomized towards once daily intravenous acetazolamide (500 mg) versus placebo, stratified according to study centre and left ventricular ejection fraction (LVEF) (≤40% vs.

Improved survival of left ventricular assist device carriers in Europe according to implantation eras: results from the PCHF-VAD registry.

Aims: Temporal changes in patient selection and major technological developments have occurred in the field of left ventricular assist devices (LVADs), yet analyses depicting this trend are lacking for Europe. We describe the advances of European LVAD programmes from the PCHF-VAD registry across device implantation eras.

Methods And Results: Of 583 patients from 13 European centres in the registry, 556 patients (mean age 53 ± 12 years, 82% male) were eligible for this analysis.

Clinical and Hemodynamic Effects of Percutaneous Edge-to-Edge Mitral Valve Repair in Atrial Versus Ventricular Functional Mitral Regurgitation.

The present study aims to assess the clinical and hemodynamic impact of percutaneous edge-to-edge mitral valve repair with MitraClip in patients with atrial functional mitral regurgitation (A-FMR) compared with ventricular functional mitral regurgitation (V-FMR). Mitral regurgitation (MR) grade, functional status (New York Heart Association class), and major adverse cardiac events (MACE; all-cause mortality or hospitalization for heart failure) were evaluated in 52 patients with A-FMR and in 307 patients with V-FMR. In 56 patients, hemodynamic assessment during exercise echocardiography was performed before and 6 months after intervention.

Treatment with sodium-glucose cotransporter-2 inhibitors in heart failure patients: The potential benefits of monitoring FGF-23 levels?

Inhibitors of sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown effective glucose-lowering effects associated with improved clinical outcomes in diabetic patients and heart failure patients. As SGLT2 inhibitors can increase phosphate levels, they can also modulate FGF-23 production, a hormone directly involved in regulation of bone and mineral metabolism, but also a strong predictor of adverse cardiovascular events. We therefore discuss the relevance of FGF-23 as a companion testing of SGLT2 treatment, in addition to standard clinical biology tests.
