Application of NASTRAN for stress analysis of left ventricle of the heart [PDF]

open access: yes, 1975
Knowing the stress and strain distributions in the left ventricular wall of the heart is a prerequisite for the determination of the muscle elasticity and contractility in the process of assessing the functional status of the heart.

Effect of hypertrophy on left ventricular diastolic function in patients with hypertrophic cardiomyopathy

open access: yesHeart International, 2006
Background. Hypertrophic cardiomyopathy (HCM) is characterized by asymmetric LV hypertrophy (LVH) and impairment in diastolic function. We assess the relationship between LVH and invasive indexes of diastolic function. Methods.

Wearable Hyperspectral Photoplethysmography Allows Continuous Monitoring of Exercise‐Induced Hypertension

open access: yesAdvanced Science, EarlyView.
A wearable hyperspectral photoplethysmography (HS‐PPG) is reported for continuous blood pressure (BP) monitoring. The HS‐PPG module integrates an ultrathin double‐folded solid immersion grating microspectrometer (DFSIG‐µSPEC), achieving a high spectral resolution of 3.4 nm.

Flavonifractor Plautii or Its Metabolite Desaminotyrosine as Prophylactic Agents for Alleviating Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
The gut microbiome is a potential target for treating cardiovascular disease. It is found that prophylactic administration of Flavonifractor plautii or its metabolite desaminotyrosine (DAT) exerts pleiotropic cardioprotective effects via promoting cardiomyocyte survival and attenuating cardiac inflammation against myocardial ischemia/reperfusion (I/R ...

Digital Sphygmomanometer Based on Arduino Using TFT LCD Display [PDF]

open access: yes, 2019
Sphygmomanometer is a human blood pressure measuring device which has several types such as mercury, digital, and aneroid. At this time, mercury Sphygmomanometer is not allowed to be used anymore considering the side effects of mercury which can harm the

rPPG-SysDiaGAN: Systolic-Diastolic Feature Localization in rPPG Using Generative Adversarial Network with Multi-Domain Discriminator [PDF]

open access: yesarXiv
Remote photoplethysmography (rPPG) offers a novel approach to noninvasive monitoring of vital signs, such as respiratory rate, utilizing a camera. Although several supervised and self-supervised methods have been proposed, they often fail to accurately reconstruct the PPG signal, particularly in distinguishing between systolic and diastolic components.

Fish Swim Bladder‐Derived ECM Hydrogels Effectively Treat Myocardial Ischemic Injury through Immunomodulation and Angiogenesis

open access: yesAdvanced Science, EarlyView.
A unique hydrogel based on extracellular matrix from fish swim bladder, which is suitable for transcatheter delivery and possesses remarkable reparative capabilities for treating heart failure, is developed. It emerges as a multi‐effect factor profoundly influencing inflammation regulation, angiogenesis, and myocardial metabolism.

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

open access: yes, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...
