Advanced Science, EarlyView.This study investigates the role of protein arginine methyltransferase 1 (PRMT1) in endothelial cells (ECs) in chronic obstructive pulmonary disease (COPD). Mice with endothelial‐specific PRMT1 deletion develop pulmonary hemorrhage, inflammation, and apoptosis, driven by excessive nuclear factor kappa B activation.

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1195-1205, December 1, 2022., 2022 Abstract Objectives Investigate age‐related changes in coronary microvascular function, its effect on hyperemic and non‐hyperemic indices of stenosis relevance, and its prognostic implications. Background Evidence assessing the effect of age on fractional flow reserve (FFR), resting mean distal intracoronary pressure/mean aortic pressure (Pd/Pa), and ...

Simulation of left ventricular function during dyskinetic or akinetic aneurysm
Biomolecules & Biomedicine, 2012 The purpose of our study was to simulate the hemodynamics of left ventricular function after left ventricular aneurysm (LVA) of various sizes and to validate the results of this computer based simulation with patient data.

Impact of blood pressure changes on myocardial work indices in hypertensive patients in a day
The Journal of Clinical Hypertension, 2022 Evaluating left ventricular function through instantaneous left ventricular deformation parameters might not always be accurate for patients with high fluctuations in blood pressure value due to afterload dependence.

A two phase harmonic model for left ventricular function [PDF]
arXiv, 2006 A minimal model for mechanical motion of the left ventricle is proposed. The model assumes the left ventricle to be a harmonic oscillator with two distinct phases, simulating the systolic and diastolic phases, at which both the amplitude and the elastic constant of the oscillator are different. Taking into account the pressure within the left ventricle,

Non-invasive assessment by B-mode ultrasound of arterial pulse wave intensity and its modification during ventricular dysfunction [PDF]
arXiv, 2022 Arterial pulse waves contain clinically useful information: their intensity varies with cardiac performance, their speed (pulse wave velocity; PWV) depends on arterial stiffness and their reflection is affected by conduit artery tone. Here we demonstrate a novel method for non-invasively assessing wave properties.

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1291-1299, December 1, 2022., 2022 Abstract Background Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. Methods TriCLASP is a prospective, single‐arm, multicenter European post‐market clinical follow‐up study (NCT04614402) to ...

Myocardial Contractions and the Ventricular Pressure--Volume Relationship [PDF]
arXiv, 2010 We present a reduced-order heart model with the aim of introducing a novel point of view in the interpretation of the pressure-volume loops. The novelty of the approach is based on the definition of active contraction as opposed to that of active stress.
