4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...

Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

open access: yesThe Journal of Physiology, EarlyView.
Abstract Figure Legend Endurance‐trained runners completed a 5‐week hot‐water‐immersion (HWI) intervention (≥40°C, 45 min, five sessions per week) and a training‐matched control period in a cross‐over design. HWI induced a 33 g increase in haemoglobin mass (Hbmass) and a 10 mL expansion in left‐ventricular end‐diastolic volume (LVEDV), resulting in a 2.

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Pancreatic cancer cachexia promotes cardiac dysfunction through altered adrenergic signalling in the heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The β1‐adrenergic receptor is the predominant adrenergic subtype expressed on cardiac myocytes. Upon stimulation it activates downstream signalling pathways that increase the heart rate and cardiac output to meet metabolic demands.

Ultrasound‐based haemodynamic force trajectories in a murine model of reversible pressure overload

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐resolution ultrasound anatomical imaging and speckle‐tracking analysis were used to compute left ventricular (LV) haemodynamic forces (HDF) in a murine model of transverse aortic constriction (TAC) followed by aortic debanding (deTAC).

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1342-1354, September 2026.
ABSTRACT Purpose Hemodynamic monitoring is essential for patients with right‐sided congenital heart disease (CHD). Respiration may have an increased impact on pulmonary flow in these patients that cannot be assessed by standard tools including 4D flow MRI. This study uses 5D flow MRI to assess respiratory‐cycle variations in flow energetics in patients
