Comprehensive exploration of unexplained dyspnoea in subjects with normal ejection fraction and low natriuretic peptides

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 879-887, April 2025.
Abstract Background Unexplained exertional dyspnoea without significant elevation of natriuretic peptides is common. One of the causes might be early heart failure with preserved ejection fraction (HFpEF). Aims This study aimed to characterize patients with exertional dyspnoea and normal/near‐to‐normal N‐terminal pro‐brain natriuretic peptide (NT ...

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

Percutaneous mechanical circulatory support for acute right heart failure: A practical approach

open access: yesESC Heart Failure, EarlyView.
This is an overview of percutaneous mechanical circulatory support options for acute right heart failure, illustrating key clinical scenarios, device types, and principles of tailored device selection based on haemodynamics and underlying pathology. Abstract Acute right heart failure (RHF) represents a critical entity with significant morbidity and ...

Surface Mn‐Enriched Doping Increasing Local Electron Concentration of Na4Fe3(PO4)2P2O7 Cathodes for Enhanced Sodium Storage

open access: yesElectron, EarlyView.
The manganese element which is concentrated on the surface layer of the particles effectively boosts the local electron concentration in Na4Fe3(PO4)2P2O7 cathode materials. This enhancement significantly increases the probability of electron transitions.
