Optimized Detection of Left Ventricular Hyperpolarized [1‐13C]Pyruvate Signal in Human Cardiac Metabolic Imaging

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 420-434, July 2026.
ABSTRACT Purpose This study aimed to improve the analysis of the left ventricular (LV) blood pool hyperpolarized [1‐13C]pyruvate signal for a more reliable quantification of downstream metabolic outcome. Methods Hyperpolarized [1‐13C]pyruvate magnetic resonance spectroscopic images were acquired dynamically at 3 Tesla in 106 participants (NCT03685175).

Improved Myocardial Sodium Quantification at 7 T Using Interleaved 23Na/1H pTx MRI With Motion and Anatomy‐Based B1 Correction

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 173-190, July 2026.
ABSTRACT Purpose To improve accuracy and repeatability of myocardial 23Na quantification in cardiac MRI at 7 T by combining retrospective respiratory and cardiac motion correction with a novel anatomy‐based B1 bias field correction. Methods In this study, a dual‐nuclear interleaved 23Na/1H MRI sequence at 7 T was applied.

Takotsubo Syndrome Mimicking Apical Hypertrophic Cardiomyopathy: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 6, June 2026.
Graphical abstract showing possible clinical findings in Takotsubo syndrome and apical hypertrophic cardiomyopathy. ABSTRACT Takotsubo syndrome (TTS) is a reversible form of cardiomyopathy that is triggered by emotional or physical stress, leading to a typical image of apical ballooning.

P2X7 receptors promote atrial remodeling and atrial fibrillation susceptibility via reactive oxygen species‐mediated mitogen‐activated protein kinase signaling activation

open access: yesJournal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Abstract Atrial fibrillation (AF), the most common clinical arrhythmia, is driven by inflammatory activation and oxidative stress, though precise molecular links remain unclear. This study identifies the P2X7 receptor as a key upstream regulator orchestrating proarrhythmic atrial remodeling through reactive oxygen species (ROS)‐mediated mitogen ...

Heart–Lung Interactions in Pulmonary Hypertension due to Heart Failure With Preserved Ejection Fraction

open access: yesComprehensive Physiology, Volume 16, Issue 3, June 2026.
This review considers heart–lung interactions in pulmonary hypertension due to heart failure with preserved ejection fraction across scales, including organ, tissue, and cell scales. Key knowledge gaps in preclinical disease models, tools for clinical phenotyping, and underlying biological mechanisms are identified for future studies.
