Submaximal 2‐day cardiopulmonary exercise testing to assess exercise capacity and post‐exertional symptom exacerbation in people with long COVID

Experimental Physiology, EarlyView.
Abstract Long COVID has a complex pathology and a heterogeneous symptom profile that impacts quality of life and functional status. Post‐exertional symptom exacerbation (PESE) affects one‐third of people living with long COVID, but the physiological basis of impaired physical function remains poorly understood. Sixty‐eight people (age (mean ± SD): 50 ±

Bilateral dynamic cerebral autoregulation assessment during endovascular treatment in large‐vessel occlusion stroke

Experimental Physiology, EarlyView.
Abstract Recanalization by endovascular treatment (EVT) is effective in acute ischaemic stroke caused by large‐vessel occlusion. Better understanding of the pathophysiology could possibly identify targets for improving peri‐procedural management and thereby patient outcome.

Inconsistency of Hemodynamic Data in Low-Gradient Severe Aortic Stenosis

Journal of the American College of Cardiology, 2016
The recently published meta-analysis by Dayan et al. [(1)][1] in the Journal evaluated the outcome and survival impact of aortic valve replacement in patients with low-gradient severe aortic stenosis (AS) in patients with preserved left ventricular ejection fraction, including paradoxical low ...

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.

Deletion of the TRPV1 channel attenuates afferent renal nerve responses to renal artery occlusion but not elevated renal pelvic pressure

The Journal of Physiology, EarlyView.
Abstract figure legend Using wild‐type and Trpv1−/− rats, we assessed the contribution of TRPV1 channels to the activation of afferent renal nerve activity (ARNA) during renal artery occlusion, graded reductions in renal blood flow and elevated renal pelvic pressure.

Integrative Evidence From Metabolome‐Wide Mendelian Randomization and Animal Models Implicates Tyrosine in Cardiac Hypercontractility and Arrhythmia Risk

Food Frontiers, Volume 7, Issue 1, January 2026.
Plasma metabolome‐wide Mendelian randomization analysis established a causal link between tyrosine and arrhythmia. GWAS meta‐analysis identified tyrosine‐associated loci linked to cardiovascular risk factors. Animal studies confirmed that oral tyrosine intake modulates heart rhythm via adrenergic signaling activation.
