Effect of the ratio of coronary arterial lumen volume to left ventricle myocardial mass derived from coronary CT angiography on fractional flow reserve.

open access: yesJournal of cardiovascular computed tomography, 2017
BACKGROUND We hypothesize that in patients with suspected coronary artery disease (CAD), lower values of the ratio of total epicardial coronary arterial lumen volume to left ventricular myocardial mass (V/M) result in lower fractional flow reserve (FFR).

A Dual‐Phase Exosomal Nanotherapy Enhances Continual Efferocytosis by Coordinating Checkpoint Inhibition and Metabolic Reprogramming in Atherosclerosis

open access: yesAdvanced Science, EarlyView.
Here we developed Am@SExo, a dual‐functional engineered exosome that coordinates CD47–SIRPα checkpoint blockade with Arg1 mRNA–mediated metabolic reprogramming. Surface SIRPα promotes recognition of apoptotic cells and plaque targeting, while Arg1 expression enhances arginine–ornithine metabolism, Rac1 activation, and actin remodeling in macrophages ...

Clinical usefulness of instantaneous wave-free ratio for the evaluation of coronary artery lesion with prior myocardial infarction: A multi-center study

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2020
Background: Fractional flow reserve (FFR) is useful for assessing the functional significance of coronary artery stenosis, even in lesions with prior myocardial infarction (pMI).

Zebrafish and CRISPR—A synergistic approach to decipher and cure human diseases

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Zebrafish, with high genetic homology to humans, serves as a powerful vertebrate model for disease modeling and drug discovery. Integration of CRISPR/Cas9 technology enables precise genome editing, facilitating the development of translational models for human diseases.

TWEAK/Fn14 Signaling Drives Oxidative Cardiac Injury in Systemic Lupus Erythematosus: Evidence From Patient Biomarker Studies, Lupus Mouse Models, and Cardiomyocyte Assays

open access: yesArthritis &Rheumatology, EarlyView.
Objective Cardiac involvement is a major cause of morbidity in systemic lupus erythematosus (SLE). Tumor necrosis factor–like weak inducer of apoptosis (TWEAK) is elevated in SLE, but its contribution to lupus‐associated cardiac injury is unclear. We investigated the role of TWEAK/fibroblast growth factor–inducible 14 (Fn14) signaling in SLE‐related ...

Fractional flow reserve of intermediate lesions on collateral donor coronary arteries after myocardial infarction [PDF]

open access: yes, 2013
Fractional flow reserve (FFR) is the gold standard for the functional assessment of coronary arteries. The aim of this study was to evaluate the relation between angiography, QCA and FFR in borderline lesions on collateral donor coronary arteries.

Diagnostic performance of on-site, CT-derived fractional flow reserve in predicting invasive fractional flow reserve and absolute myocardial blood flow

open access: yesEuropean Heart Journal - Cardiovascular Imaging
Abstract Background Computed tomography (CT)-derived fractional flow reserve (FFR) improves the diagnostic accuracy of coronary CT angiography (CCTA) but requires off-site transfer of images and long processing times.

Prediction of fractional flow reserve with angiographic DILEMMA score

open access: yes, 2017
Objective: Angiographic assessment of stenosis has limited predictive value for functionally significant lesions compared with fractional flow reserve (FFR). The recently developed angiographic DILEMMA score, which consists of minimal lumen diameter (MLD)
