Temporal Changes of Cardiac Structure, Function, and Mechanics During Sub-acute Cervical and Thoracolumbar Spinal Cord Injury in Humans: A Case-Series

Frontiers in Cardiovascular Medicine, 2022
Individuals with cervical spinal cord injury (SCI) experience deleterious changes in cardiac structure and function. However, knowledge on when cardiac alterations occur and whether this is dependent upon neurological level of injury remains to be ...

Will the real ventricular architecture please stand up? [PDF]

, 2017
Ventricular twisting, essential for cardiac function, is attributed to the contraction of myocardial helical fibers. The exact relationship between ventricular anatomy and function remains to be determined, but one commonly used explanatory model is the ...

Impact of Aortic Stenosis on Myofiber Stress: Translational Application of Left Ventricle-Aortic Coupling Simulation

Frontiers in Physiology, 2020
The severity of aortic stenosis (AS) has traditionally been graded by measuring hemodynamic parameters of transvalvular pressure gradient, ejection jet velocity, or estimating valve orifice area.

Higher Ventricular-Arterial Coupling Derived from Three-Dimensional Echocardiography Is Associated with a Worse Clinical Outcome in Systemic Sclerosis

Pharmaceuticals, 2021
Primary myocardial involvement is common in systemic sclerosis (SSc). Ventricular-arterial coupling (VAC) reflecting the interplay between ventricular performance and arterial load, is a key determinant of cardiovascular (CV) performance.

Left ventricular systolic function evaluated by strain echocardiography and relationship with mortality in patients with severe sepsis or septic shock. a systematic review and meta-analysis [PDF]

, 2018
Sepsis-induced myocardial dysfunction is associated with poor outcomes, but traditional measurements of systolic function such as left ventricular ejection fraction (LVEF) do not directly correlate with prognosis.

Cardiac Chamber Quantification by Echocardiography in Adults: Recommendations from the Association of Cardiovascular Surgeons of Ukraine and Ukrainian Society of Cardiology

Український журнал серцево-судинної хірургії, 2020
Fast technology development over the past decade as well as changes in practical echocardiography (EchoCG) lead to have given rise to a need in the update of previous guidelines for cardiac chambers quantification, which was the aim of this publication ...

Describing right ventricular function [PDF]

European Respiratory Journal, 2013
In pulmonary hypertension and other conditions, such as acute respiratory distress syndrome and left heart failure, right ventricular dysfunction is a prognostic determinant. Therefore, functional parameters pertaining to the right heart alone,i.e.independent of its loading conditions, should be used to quantify right ventricular disease progression ...

Thyroid hormone levels within reference range are associated with heart rate, cardiac structure, and function in middle-aged men and women [PDF]

, 2013
Background: Triiodothyronine (T3) has many effects on the heart, and marked changes in cardiac function and structure occur in patients with (subclinical) thyroid disease. We investigated whether between-subject variation in thyroid hormone levels within

Synergistic Model of Cardiac Function with a Heart Assist Device [PDF]

, 2019
The breakdown of cardiac self-organization leads to heart diseases and failure, the number one cause of death worldwide. The left ventricular pressure–volume relation plays a key role in the diagnosis and treatment of heart diseases.
