Strain‐based characterization of atrioventricular and left atrial remodelling in rat models of heart failure with preserved ejection fraction

Experimental Physiology, EarlyView.
Abstract Current experimental models of heart failure with preserved ejection fraction (HFpEF) lack standardized approaches for evaluating left atrial (LA) remodelling and atrioventricular (AV) coupling, leaving a critical gap in mechanistic understanding and phenotypic characterization. This study aimed to explore LA function and AV coupling status in

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...
