Electrocardiographic and electrophysiological characteristics of premature ventricular complexes associated with left ventricular dysfunction in patients without structural heart disease.

open access: yesEuropace, 2013
AIMS The mechanism responsible for premature ventricular complex (PVC)-mediated left ventricular (LV) dysfunction remains unclear. We sought to determine the electrocardiographic and electrophysiological characteristics of PVC-mediated LV dysfunction ...

Decursin‐Loaded Nanovesicles Target Macrophages Driven by the Pathological Process of Atherosclerosis

open access: yesAdvanced Science, EarlyView.
This study presents decursin, a traditional Chinese medicine monomer, that inhibits lipid accumulation and inflammation in atherosclerosis through PKCδ interaction. A novel targeted delivery system (ALD@EM) is developed to overcome decursin's short half‐life, combining antibody‐mediated targeting, LDL‐facilitated chemotaxis, and enhanced macrophage ...

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

open access: yesCatheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Effects of the mechanical ventilation on the cardiovascular system [PDF]

open access: yes, 2014
Mechanical ventilation with positive pressure significantly influences cardiovascular system function. The main effects are a decrease of right ventricular preload and a decrease of left ventricular afterload.

Biomass Fuel Use and Cardiac Function in Nepali Women. [PDF]

open access: yes, 2020
BackgroundExposure to household air pollution (HAP) from cooking with biomass fuel affects billions of people. We hypothesized that HAP from woodsmoke, compared to other household fuels, was associated with adverse cardiovascular outcomes, of which there

Leucine‐Rich Repeat‐Containing G Protein‐Coupled Receptor 6 Ameliorates Pressure Overload‐Induced Cardiac Hypertrophy by Regulating Cardiomyocyte Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
LGR6 overexpression ameliorates cardiac hypertrophy by regulating metabolic reprogramming through USP4‐PPARα pathway. Abstract Metabolic reprogramming is a pivotal mechanism in the pathogenesis of pathological cardiac hypertrophy. Leucine‐rich repeat‐containing G protein‐coupled receptor 6 (Lgr6) has emerged as a significant player in cardiovascular ...

Age‐related changes in the coronary microcirculation influencing the diagnostic performance of invasive pressure‐based indices and long‐term patient prognosis

open access: yesCatheterization 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 ...

A two phase harmonic model for left ventricular function [PDF]

open access: yesarXiv, 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,

Acute left ventricular dysfunction secondary to right ventricular septal pacing in a woman with initial preserved contractility: a case report [PDF]

open access: yes, 2011
Introduction Right ventricular apical pacing-related heart failure is reported in some patients after long-term pacing. The exact mechanism is not yet clear but may be related to left ventricular dyssynchrony induced by right ventricular apical pacing ...
