Seasonal variations in ventricular repolarization and tachyarrhythmias in hibernating brown bears (Ursus arctos arctos)

open access: yesPhysiological Reports, Volume 13, Issue 17, September 2025.
Abstract In humans, hypothermia prolongs ventricular repolarization and associates with sustained ventricular tachyarrhythmias. In bears, body temperature drops during hibernation similar to moderate human hypothermia, yet they rarely face fatal outcomes during the winter. This suggests protective adaptations in bear electrophysiology.

Laser‐Induced Graphene‐Assisted Patterning and Transfer of Silver Nanowires for Ultra‐Conformal Breathable Epidermal Electrodes in Long‐Term Electrophysiological Monitoring

open access: yesAdvanced Functional Materials, Volume 35, Issue 31, August 1, 2025.
This study presents a novel method using laser‐induced graphene (LIG) to enable high‐yield transfer of silver nanowire (AgNW) networks onto ultra‐low modulus, breathable silicone substrates. This approach creates ultra‐conformal epidermal electrodes (≈50 µm) for long‐term, high‐fidelity electrophysiological monitoring, even in challenging conditions ...

Electrocardiographic R Wave Peak Time: Correlation With the Severity of Coronary Artery Disease and Prognosis in Patients With Acute Coronary Syndrome

open access: yesCatheterization and Cardiovascular Interventions, Volume 106, Issue 2, Page 1225-1232, August 1, 2025.
ABSTRACT Background Electrocardiographic parameters have emerged as valuable noninvasive markers for risk stratification in acute coronary syndrome (ACS). Aims This study aimed to evaluate the correlation between R wave peak time (RWPT) and coronary artery disease (CAD) severity, and to assess its prognostic value for in‐hospital major adverse cardiac ...

Early Detection of Treatment Response to Mavacamten in Hypertrophic Obstructive Cardiomyopathy With Severe Mitral Regurgitation Using Magnetocardiography

open access: yesClinical Case Reports, Volume 13, Issue 8, August 2025.
ABSTRACT Recent evidence highlights the efficacy of mavacamten in reducing left ventricular outflow tract (LVOT) gradients in patients with hypertrophic cardiomyopathy (HCM), which is illustrated in this case. Additionally, the potential of magnetocardiography (MCG) as a novel, objective diagnostic and monitoring tool for nonischemic cardiomyopathies ...

Transthyretin amyloid cardiomyopathy in aortic stenosis patients scheduled for transcatheter aortic valve implantation

open access: yesESC Heart Failure, Volume 12, Issue 4, Page 2467-2476, August 2025.
Abbreviations: TAVI, transcatheter aortic valve implantation; ATTR‐CM, transthyretin cardiac amyloidosis. We aimed to diagnose occult ATTR‐CM in patients with severe aortic stenosis undergoing TAVI using bone scintigraphy. We verified a diagnosis of ATTR‐CM in 8 of 171 (4.7 %) consecutive aortic stenosis patients who underwent TAVI.
