Longitudinal Analysis of Quality of Life, Clinical, Radiographic, Echocardiographic, and Laboratory Variables in Dogs with Preclinical Myxomatous Mitral Valve Disease Receiving Pimobendan or Placebo: The EPIC Study [PDF]

, 2018
Background: Changes in clinical variables associated with the administration of pimobendan to dogs with preclinical myxomatous mitral valve disease (MMVD) and cardiomegaly have not been described. Objectives: To investigate the effect of pimobendan on

NO and cardiac diastolic function [PDF]

Cardiovascular Research, 1999
Time for primary review 34 days. Since the first report of a role for nitric oxide (NO) in modulating myocardial contractile function in 1991 [1], an enormous number of studies have been published in this field (recently reviewed in Refs. [2–4]). It is now recognised that, under physiological conditions, the major sources of NO that are important for

Comparison of cardiac DTI parameters between systole and diastole

Journal of Cardiovascular Magnetic Resonance, 2014
Results Two of the original 46 volunteers were excluded due to ECG irregularities. Data from one further volunteer was incomplete and therefore excluded from the final analysis. Results from the remaining 43 volunteers are in table 1.

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Volumetric 3D Printing and Melt‐Electrowriting to Fabricate Implantable Reinforced Cardiac Tissue Patches

Advanced Materials, EarlyView.
This study presents an implantable reinforced cardiac patch (RCPatch) combining volumetrically 3D‐printed metamaterials with melt‐electrowritten (MEW) meshes. The design integrates tunable stiff polymer structures with soft, cell‐laden hydrogels. The RCPatch withstands suturing, intraventricular pressure, and cardiac contraction in a large animal ...

RETRACTED ARTICLE: Assessment of fetal intraventricular diastolic fluid dynamics using ultrasound vector flow mapping

BMC Cardiovascular Disorders, 2023
Objective The purpose of this study was to investigate the feasibility of visualizing and quantifying the normal pattern of vortex formation in the left ventricle (LV) and right ventricle (RV) of the fetal heart during diastole using vector flow mapping (

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]

, 2019
BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

Hypoglycemia Induces Diabetic Macrovascular Endothelial Dysfunction via Endothelial Cell PANoptosis, Macrophage Polarization, and VSMC Fibrosis

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.
