PM2.5 Induce Endothelial‐Mesenchymal Transition and Cardiac Fibrosis via the NCOA4‐Mediated Ferritinophagy

open access: yesAdvanced Science, EarlyView.
This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

Raised Prosthetic Valve Gradients: What Should be the Approach?

open access: yesJournal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019
The introduction of valve replacement surgery has dramatically improved the outcome of patients with valvular heart disease. Echocardiography plays an important role to determine the outcome of the surgery and follow up of these patients with prosthetic ...

Impaired myocardial relaxation with exercise determines peak aerobic exercise capacity in heart failure with preserved ejection fraction [PDF]

open access: yes, 2017
Background Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome characterized by impaired exercise capacity due to shortness of breath and/or fatigue.

Engineered Multifunctional Hydrogel Delivering Novel CBX7 Inhibitor Modulates Cuproptosis Via Liquid–Liquid Phase Separation to Restore Cardiac Function in Aged Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
An age‐adapted therapy pairs δ‐Amyrenone, a CBX7 inhibitor, with an alginate hydrogel (CSAδ) to rescue infarcted elderly hearts. CSAδ disrupts CBX7–ATP7A liquid–liquid phase separation, restores ATP7A trafficking and copper efflux, suppresses cuproptosis, supplies oxygen, scavenges ROS, promotes M2 polarization, supports angiogenesis, and enhances ...

Effects of anesthesia on conventional and speckle tracking echocardiographic parameters in a mouse model of pressure overload [PDF]

open access: yes, 2015
Genetically‑modified mice are widely applied in cardiovascular studies as model organisms. Echocardiography is a key tool for evaluating cardiac and hemodynamic functions in mice.

Ythdc1‐p300‐Klf5 Complex‐Mediated Golgi Dysfunction Promotes Aortic Aneurysm

open access: yesAdvanced Science, EarlyView.
In their Research Article (DOI: https://doi.org/10.1002/advs.202512116* lF: 14.1 Q1), Wenli Wang and co‐workers identifies a novel lncRNA m6A modification‐dependent regulatory mechanism of vascular homeostasis, and constructs a predictive model for post‐operative short‐term death based on AD patient's features, providing a platform to be able to ...

Transthoracic Doppler echocardiography – noninvasive diagnostic window for coronary flow reserve assessment

open access: yesCardiovascular Ultrasound, 2003
This review focuses on transthoracic Doppler echocardiography as noninvasive method used to assess coronary flow reserve (CFR) in a wide spectrum of clinical settings. Transthoracic Doppler echocardiography is rapidly gaining appreciation as popular tool

Automated 4D flow cardiac MRI pipeline to derive peak mitral inflow diastolic velocities using short-axis cine stack: two centre validation study against echocardiographic pulse-wave doppler

open access: yesBMC Cardiovascular Disorders, 2023
Background Measurement of peak velocities is important in the evaluation of heart failure. This study compared the performance of automated 4D flow cardiac MRI (CMR) with traditional transthoracic Doppler echocardiography (TTE) for the measurement of ...

Trigonelline Improves Metabolism and Cardiac Function of HFpEF Mice Via Gut Microbiome Alterations‐Mediated AMPK Activation

open access: yesAdvanced Science, EarlyView.
Metabolomics analyses reveal that trigonelline is markedly reduced in HFpEF hearts. Trigonelline supplementation alleviates metabolic disorders and improves cardiac function in HFpEF mice via gut microbiota‐mediated AMPK activation. Abstract Heart failure with preserved ejection fraction (HFpEF) is a prevalent end‐manifestation of cardiovascular ...

A case of hypertrophic cardiomyopathy combined with muscular ventricular septal defect and abnormal origin of right coronary artery

open access: yesBMC Cardiovascular Disorders, 2019
Background Hypertrophic cardiomyopathy (HCM) is a myocardial disease. However, the coexistence of HCM with muscular ventricular septal defect (VSD), especially those with both incomplete spontaneous closure and coronary abnormal origin, is relatively ...
