On in-silico estimation of left ventricular end-diastolic pressure from cardiac strains [PDF]

2024 46th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), pp. 1-4
Left ventricular diastolic dysfunction (LVDD) is a group of diseases that adversely affect the passive phase of the cardiac cycle and can lead to heart failure. While left ventricular end-diastolic pressure (LVEDP) is a valuable prognostic measure in LVDD patients, traditional invasive methods of measuring LVEDP present risks and limitations ...

PRMT1 Ablation in Endothelial Cells Causes Endothelial Dysfunction and Aggravates COPD Attributable to Dysregulated NF‐κB Signaling

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.

Effect of prolonged space flight on cardiac function and dimensions [PDF]

Echocardiographic studies were performed preflight 5 days before launch and on recovery day and 1, 2, 4, 11, 31 and 68 days postflight. From these echocardiograms measurements were made.

A Novel Protein NAB1‐356 Encoded by circRNA circNAB1 Mitigates Atrial Fibrillation by Reducing Inflammation and Fibrosis

Advanced Science, EarlyView.
The circRNA circNAB1 is downregulated in AF patient. Silencing circNAB1 promotes collagen deposition and inflammation, whereas overexpression reduces AF susceptibility. circNAB1 encodes the protein NAB1 356 that interacts with EGR1 to mitigate fibrosis and inflammation.

Left Ventricle Diastolic Function in Patients Underwent Chemotherapy with Doxorubicin

Majalah Kardiologi Indonesia, 2013
Background. Doxorubicin is one of the first-line chemoterapy against many form of neoplasm but the use is hampered by its cardiotoxic poten-tial with the end result of congestive heart failure.

Application of Fractional Derivatives in Characterization of ECG graphs of Right Ventricular Hypertrophy Patients [PDF]

arXiv, 2017
There are many functions which are continuous everywhere but non-differentiable at some or all points such functions are termed as unreachable functions. Graphs representing such unreachable functions are called unreachable graphs. For example, ECG is such an unreachable graph.

Current clinical applications of spectral tissue Doppler echocardiography (E/E' ratio) as a noninvasive surrogate for left ventricular diastolic pressures in the diagnosis of heart failure with preserved left ventricular systolic function [PDF]

, 2007
Congestive heart failure with preserved left ventricular systolic function has emerged as a growing epidemic medical syndrome in developed countries, which is characterized by high morbidity and mortality rates.

Impact of Bariatric Surgery on Left Ventricular Structure and Function

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Obesity leads to an increased risk of cardiovascular disease morbidity and death, including heart failure. Bariatric surgery has been proven to be the most effective long‐term weight management treatment. This study investigated the changes in
