Role of Autonomic Dysfunction in Initiating Postoperative Atrial Fibrillation in a Canine Sterile Pericarditis Model

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Autonomic dysfunction plays a significant role in initiating postoperative atrial fibrillation (POAF) by causing atrial ectopic triggers, potentially through mechanisms such as increased sympathetic activity and altered vagal tone.

Acute alterations in blood lactate in the setting of transient stress induced myocardial ischaemia

Experimental Physiology, EarlyView.
Abstract An elevation in resting venous blood lactate ([La−]b) levels in conditions of myocardial hypoperfusion is associated with adverse prognosis and survival. This investigation aimed to assess changes in venous [La−]b levels induced by dobutamine stress in the presence and absence of myocardial ischaemia and adverse outcomes at 1 year.

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 ...

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Loss of wall stress homoeostasis in ascending thoracic aortic aneurysm: histomorphometric insights into patient variants

The Journal of Physiology, EarlyView.
Abstract figure legend Dynamic interplay between the extracellular matrix (ECM) and vascular smooth muscle cells (VSMCs) in the medial layer of ascending thoracic aortic aneurysms (ATAA) associated with two variants: thickening (hypertrophic) and thinning (hypotrophic) aneurysm remodelling.
