Left Ventricular wall Thickness and Decrement Evoked Potentials in Ablation of Ischemic Ventricular Tachycardia

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Preprocedural imaging can improve the success rate of ventricular tachycardia (VT) ablation. Left ventricular wall thickness (LVWT) measured by cardiac computed tomography (CT) can be used to identify infarct regions. We sought to determine whether an association exists between left ventricular wall thickness (LVWT) as obtained ...

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

open access: yesExperimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Electromechanical modelling and simulation of human‐induced pluripotent stem cell‐derived cardiomyocytes predict drug‐induced contractility effects

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Mechanistic insights into sex differences in atrial electrophysiology and arrhythmia vulnerability through sex‐specific computational models

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sex‐specific models of the human atrial myocyte in normal sinus rhythm (nSR) and chronic atrial fibrillation (cAF) revealed increased alternans susceptibility in cAF males and DADs in females, driven primarily by ICaL and ryanodine receptor remodelling.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Resistant to Ablation, Responsive to Hydroquinidine: Precision Medicine Guides Recovery in MEPPC Syndrome Cardiomyopathy

open access: yesJournal of Arrhythmia, Volume 42, Issue 3, June 2026.
We report a case of MEPPC syndrome presenting with severe dilated cardiomyopathy due to a pathogenic SCN5A p.Arg814Trp variant. Genetic diagnosis enabled precision pharmacotherapy with hydroquinidine, which suppressed multifocal Purkinje‐origin ectopy resistant to catheter ablation and led to marked improvement in left ventricular function.

Prevalence and impact of prescribing cascades in community‐dwelling adults: Longitudinal analysis of the Irish longitudinal study on ageing (TILDA)

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 5, Page 1500-1508, May 2026.
Prescribing cascades occur when medication is prescribed to prevent/treat the adverse effects of another medication and may be intentional/unintentional. This study examines the prevalence of nine prescribing cascades (ThinkCascades) in The Irish Longitudinal StuDy on Ageing (TILDA).
