Unraveling septal perfusion abnormalities in Ebstein's anomaly: A case report contrasting PET MPI with myocardial reality

Radiology Case Reports
In Ebstein's anomaly, septal perfusion abnormality poses a challenge in traditional interpretations of myocardial blood flow. We report a single case of a 43‐year‐old female with known Ebstein’s anomaly who was referred for preoperative cardiac ...

A Monte Carlo study of arms effect in myocardial perfusion of normal and abnormal cases utilizing STL heart shape

Results in Physics, 2018
Arms influence in myocardial perfusion single photon emission computed tomography (SPECT) imaging has been studied for the last two decades. These studies suggested that arms positioning next to the patient would not show cardiac abnormalities or ...

Fractional flow reserve versus angiography in guiding management to optimize outcomes in non–ST-elevation myocardial infarction (FAMOUS-NSTEMI): rationale and design of a randomized controlled clinical trial [PDF]

, 2013
<p>Background: In patients with acute non–ST-elevation myocardial infarction (NSTEMI), coronary arteriography is usually recommended; but visual interpretation of the angiogram is subjective.

Preservation of ALYREF Phase Separation Mitigates Doxorubicin‐Induced Cardiomyocyte DNA Damage and Cardiotoxicity

Advanced Science, EarlyView.
Binding of Doxorubicin to ALYREF disrupts its phase‐separated condensate and induces DNA damage and apoptosis in cardiomyocytes Abstract The clinical utility of the anticancer agent doxorubicin (DOX) is limited by its dose‐dependent cardiotoxicity.

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

Advanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

A Redox‐Active and Electroactive Hydrogel Enabled by an Integrated PEDOT@PMOF Nanofiller for Post‐Infarct Myocardial Repair

Advanced Science, EarlyView.
An integrated nanoparticle PEDOT@PMOF is constructed as a redox‐active nanozyme and electroactive nanofiller in a cell‐affinity hydrogel platform for acute MI treatment. It is demonstrated that MOF‐based nanozymes have good catalytic ability, and the incorporation of PEDOT increases the conductivity.

Mechanical chest-compression devices: current and future roles [PDF]

, 2010
Purpose of review: It is recognised that the quality of CPR is an important predictor of outcome from cardiac arrest yet studies consistently demonstrate that the quality of CPR performed in real life is frequently sub-optimal.

HMGB2 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through MTA2‐Driven Metabolic Reprogramming

Advanced Science, EarlyView.
In contrast to the adult mammalian heart, which lacks regenerative capacity, the neonatal heart retains a transient regenerative capacity. In this study, high mobility group box 2 (HMGB2) is identified as a crucial protein driving heart regeneration based on comprehensive analyses using quantitative proteomics with tandem mass tag (TMT) labelling, RNA ...
