PEDOT:PSS—A Key Material for Bioelectronics

open access: yesAdvanced Science, EarlyView.
PEDOT:PSS ‐ Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate ‐ is typically processed from water dispersions to form multifunctional and multidimensional constructs with tunable electronic and ionic conductivity. Throught processing engineering, PEDOT:PSS is intergrated in bioelectronic devices that operate efficiently in physiological conditions

Towards Phenotyping Characteristics and Mechanism of Conduction Delay in Patients With Nonischemic Heart Failure With Reduced Ejection Fraction: Insights From Cardiac Magnetic Resonance Imaging

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Considering that 30% to 40% of patients do not benefit from cardiac resynchronization therapy implantation, it is insufficient to evaluate patients with heart failure with reduced ejection fraction solely based on QRS duration and morphology ...

Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricle

open access: yesCardiovascular Ultrasound, 2006
Background The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering ...

Three-dimensional echocardiography and 2D-3D speckle tracking imaging in chronic pulmonary hypertension. diagnostic accuracy in detecting hemodynamic signs of RV failure [PDF]

open access: yes, 2015
Background and objective. Our aim was to compare three-dimensional (3D) and 2D and 3D speckle tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH ...

HEART FAILURE WITH MID-RANGE LEFT VENTRICULAR EJECTION FRACTION

open access: yesWiadomości Lekarskie, 2020
The aim of the publication was to review available data on epidemiology, pathophysiological and clinical aspects of HFmrEF as a specific HF pattern. Materials and methods: We carried out the analysis of the publications that appeared during last decade, related to the different aspects of HFmrEF. The literature search was conducted by use of Google Web

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 ...

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

open access: yesAdvanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...
