Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

The Immuno‐Cardiovascular Storm of Pre‐Eclampsia: Cytokine‐Mediated Endothelial Injury, Thrombosis, and Maternal Cardiovascular Instability

Comprehensive Physiology, Volume 16, Issue 4, August 2026.
Placental ischemia in pre‐eclampsia initiates cytokine‐driven endothelial dysfunction, angiogenic imbalance, oxidative stress, and thromboinflammation. Elevated TNF‐α, IL‐6, IL‐17, sFlt‐1, and complement activation promote vasoconstriction, thrombosis, and cardiovascular instability.

Dynamic Mode Decomposition (DMD) for Low‐Latency Real‐Time Cardiac MRI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 623-634, August 2026.
ABSTRACT Purpose To demonstrate dynamic mode decomposition (DMD) for high spatiotemporal low‐latency online reconstruction in 2D real‐time cardiac MRI. Methods DMD was applied to 2D spiral balanced steady state free precession (bSSFP) real‐time adult and fetal cardiac MRI at 0.55 T, with data from 10 healthy adult volunteers (3F/7M; age: 21–49; BMI: 20–

Evaluation of a Point‐of‐Care Viscoelastic Coagulation Monitor (VCM Vet) and Thromboelastography (TEG) in Bonobos (Pan paniscus)

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Introduction Bonobos (Pan paniscus) are endangered and uncommon in managed care. Prothrombotic and hypofibrinolytic states are encountered with cardiovascular disease, ischemic stroke, and neoplasia. Materials and Methods Twelve bonobos from one institution were evaluated during anesthetized exams.

Temporal Trends and Short‐ and Long‐Term Mortality of People With Acute Myocardial Infarction and Rheumatoid Arthritis: A Nationwide Cohort Study

Arthritis Care &Research, Volume 78, Issue 7, Page 850-859, July 2026.
Objective We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analyzed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalized with AMI between 2005 and 2019 from the Myocardial Ischaemia ...
