Visualization of Minute Mechanical-Excitation/Relaxation Wave-front Propagation in Myocardial Tissue [PDF]
, 2010 Unlike the case of skeletal muscle, the direction of myocardial contraction does not coincide with the direction of work necessary to eject the intraventricular blood, contributing to great complexity of the wall deformation sequence of cardiac ...

Dynamic finite-strain modelling of the human left ventricle in health and disease using an immersed boundary-finite element method [PDF]
, 2014 Detailed models of the biomechanics of the heart are important both for developing improved interventions for patients with heart disease and also for patient risk stratification and treatment planning.

Modeling 3D cardiac contraction and relaxation with point cloud deformation networks [PDF]
arXiv, 2023 Global single-valued biomarkers of cardiac function typically used in clinical practice, such as ejection fraction, provide limited insight on the true 3D cardiac deformation process and hence, limit the understanding of both healthy and pathological cardiac mechanics.

Key Trends and Insights in Smart Polymeric Skin Wearable Patches
Advanced Engineering Materials, EarlyView.Intelligent polymers, which respond to various physical and biological stimuli, are explored for the development of skin wearable patches in biomedical applications. Smart polymers, also known as intelligent or stimuli‐responsive polymers, play a crucial role in the development of advanced wearable patches due to their versatility and softness.

Angina de Prinzmetal Angina de Prinzmetal Prinzmetal's angina
Arquivos Brasileiros de Cardiologia, 2009 Essa síndrome é causada por um espasmo focal de uma artéria coronária epicárdica, levando a isquemia miocárdica grave. Embora freqüentemente acredite-se que o espasmo ocorra em artérias sem estenose, muitos pacientes com angina de Prinzmetal apresentam ...

Cardiac Dysfunction Induced by Obesity Is Not Related to β-Adrenergic System Impairment at the Receptor-Signalling Pathway. [PDF]
PLoS ONE, 2015 Obesity has been shown to impair myocardial performance. Some factors have been suggested as responsible for possible cardiac abnormalities in models of obesity, among them beta-adrenergic (βA) system, an important mechanism of regulation of myocardial ...

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Losartan Treatment Attenuates Tumor-induced Myocardial Dysfunction [PDF]
, 2015 Fatigue and muscle wasting are common symptoms experienced by cancer patients. Data from animal models demonstrate that angiotensin is involved in tumor-induced muscle wasting, and that tumor growth can independently affect myocardial function, which ...
