Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

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

The 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.
