Stress Myocardial Perfusion Imaging Interpretation From the Viewpoint of Fractional Flow Reserve
Circulation Journal, 2021 Myocardial perfusion imaging (MPI) and fractional flow reserve (FFR) are established approaches to the assessment of myocardial ischemia. Recently, various FFR cutoff values were proposed, but the diagnostic accuracy of MPI in identifying positive FFR using various cutoff values is not well established.We retrospectively studied 273 patients who ...

Fractional flow reserve and myocardial perfusion by computed tomography: a guide to clinical application [PDF]
European Heart Journal - Cardiovascular Imaging, 2017 The aim of this paper is to provide a guide to the clinical application of the functional computed tomography (CT) techniques fractional flow reserve (CT FFR) and myocardial perfusion (CTP) in patients presenting for the evaluation of coronary artery disease (CAD). Both techniques have recently been introduced to complement coronary CT angiography (CTA)

3D Printing of Conducting Polymer Hydrogels for Electrostimulation‐Assisted Tissue Engineering
Advanced Materials, EarlyView.This review highlights nanosized inherently conducting polymers (ICPs) as promising ink constituents for 3D printing of conducting hydrogel (CH)‐based electrostimulation (ES) devices. ICP‐based ink formulation, 3D printing, and solidification strategies are discussed, along with the application of 3D‐printed ICP‐based CHs as ES platforms for regulating

Advanced Science, EarlyView.This study investigates hypoglycemia‐induced diabetic macrovascular endothelial dysfunction. It reveals that hypoglycemia triggers ZBP1‐dependent PANoptosis of endothelial cells, proinflammatory polarization of macrophages, and fibrosis of vascular smooth muscle cells (VSMCs) in diabetic mice.

Application of pressure-derived myocardial fractional flow reserve in chronic hemodialysis patients [PDF]
Journal of Cardiology, 2018 Although fractional flow reserve (FFR) measurements during coronary angiography are performed in routine clinical practice, few studies have evaluated FFR measurements in dialysis patients.We retrospectively studied 42 hemodialysis patients with suspected or known coronary artery disease (CAD) who underwent stress myocardial perfusion imaging and ...

Advanced Science, EarlyView.Irisin is a crucial plasma biomarker and promising therapeutic target that reflects disease severity, pulmonary vascular remodeling status and clinical outcome in patients with pulmonary arterial hypertension (PAH). As a novel protective factor, irisin is downregulated in PAH. By ubiquitination, irisin promotes Enolase 1 degradation and suppresses cell
