An Infusible Decellularized Extracellular Matrix Material Binds to Vasculature in Infarcted Myocardium and Induces Pro‐Reparative Gene Expression Following Acute Myocardial Infarction Through Inherent Avidity and Bioactive Signaling

Advanced Science, EarlyView.
To better characterize an infusible extracellular matrix (iECM) material, we applied size‐based fractionation to separate out components into two major fractions. We characterized these fractions to understand how material properties such as composition, morphology, and biochemical properties affect bioactive effects in the context of acute myocardial ...

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

Advanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

The Effect of Ivabradine on the Human Atrial Myocardial Contractility in an In Vitro Study

Cardiology Research and Practice, 2019
Purpose. Ivabradine has emerged as a new antiarrhythmic agent that could compete with the traditional ones, such as beta-blockers. This experimental study aims to ascertain whether ivabradine directly interferes with the myocardial contractility in an in

Ischemic preconditioning affects phosphosites and accentuates myocardial stunning while reducing infarction size in rats

Frontiers in Cardiovascular Medicine
Background and aimsIschemic preconditioning (IPC), i.e., brief periods of ischemia, protect the heart from subsequent prolonged ischemic injury, and reduces infarction size. Myocardial stunning refers to transient loss of contractility in the heart after

SFMFNet: Spatial‐Frequency Multiscale Fusion Network for Left Ventricle Segmentation in Echocardiography

Advanced Intelligent Systems, EarlyView.
Automatic left ventricular segmentation in echocardiography is critical for cardiac function assessment but remains challenging due to limited crossdomain feature interaction. This paper proposes SFMFNet, a Spatial‐Frequency Multi‐Scale Fusion Network that integrates multiscale convolution, wavelet transform, and Fourier transform.

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...
