Challenges in clinical translation of cardiac magnetic resonance imaging radiomics in non-ischemic cardiomyopathy: a narrative review.
Cardiovasc Diagn Ther

The First Affiliated Hospital, Department of Cardiology, Hengyang Medical School, University of South China, Hengyang, China.
Background And Objective: Radiomics is an emerging technology that facilitates the quantitative analysis of multi-modal cardiac magnetic resonance imaging (MRI). This study aims to introduce a standardized workflow for applying radiomics to non-ischemic cardiomyopathies, enabling clinicians to comprehensively understand and implement this technology in clinical practice.
Methods: A computerized literature search (up to August 1, 2024) was conducted using PubMed to identify relevant studies on the roles and workflows of radiomics in non-ischemic cardiomyopathy.
Perinuclear organelle trauma at the nexus of cardiomyopathy pathogenesis arising from loss of function mutation.

Center for Translational Medicine, Department of Medicine, Thomas Jefferson University, Philadelphia, PA, USA.
Over the past 25 years, nuclear envelope (NE) perturbations have been reported in various experimental models with mutations in the gene. Although the hypothesis that NE perturbations from mutations are a fundamental feature of striated muscle damage has garnered wide acceptance, the molecular sequalae provoked by the NE damage and how they underlie disease pathogenesis such as cardiomyopathy ( cardiomyopathy) remain poorly understood. We recently shed light on one such consequence, by employing a cardiomyocyte-specific deletion in the adult heart.

January 2025
Institute of Basic Medical Sciences of Xiyuan Hospital, Beijing Key Laboratory of Chinese Materia Pharmacology, China Academy of Chinese Medical Sciences, National Clinical Research Center of Traditional Chinese Medicine for Cardiovascular Diseases, Beijing, China.
Objectives: This study intended to explore whether the protective effect safflower yellow injection (SYI) on myocardial ischemia-reperfusion (I/R) injury in rats mediated of the NLRP3 inflammasome signaling.
Methods: The I/R model was prepared by ligating the left anterior descending coronary artery for 45 min and then releasing the blood flow for 150 min. 96 male Wistar rats were randomly divided into sham group, I/R group, Hebeishuang group (HBS), SYI high-dose group (I/R + SYI-H), SYI medium-dose group (I/R + SYI-M) and SYI low-dose group (I/R + SYI-L).
Poincaré plot analysis of ECG uncovers beneficial effects of omaveloxolone in a mouse model of Friedreich's ataxia.

Department of Molecular Biosciences, University of California, Davis, CA, USA; Department of Basic Sciences, California Northstate University, Elk Grove, CA. Electronic address:
Background: Friedreich's ataxia (FA) is a rare inherited neuromuscular disorder, where most patients die from lethal cardiomyopathy and arrhythmias. Mechanisms leading to arrhythmic events in FA patients are poorly understood.
Objective: This study aims to examine cardiac electrical signal propagation in mouse model of FA with severe cardiomyopathy and evaluate effects of omaveloxolone (OMAV), the first FDA-approved therapy.
Prognostic Value of Myocardial CT-ECV in Severe Aortic Stenosis Requiring Aortic Valve Replacement: A Systematic Review and Meta-analysis.
Eur Heart J Cardiovasc Imaging
January 2025
Department of Perioperative Cardiology and Cardiovascular Imaging, Centro Cardiologico Monzino IRCCS, Milan, Italy.
Aim: Computed tomography (CT)-derived extracellular volume fraction (ECV) is a non-invasive method to quantify myocardial fibrosis. Evaluating CT-ECV during aortic valve replacement (AVR) planning CT in severe aortic stenosis (AS) may aid prognostic stratification. This meta-analysis evaluated the prognostic significance of CT-ECV in severe AS necessitating AVR.
