Echocardiographic Evaluation of Ventricular Function—For the Neonatologist and Pediatric Intensivist

Frontiers in Pediatrics, 2018
In the neonatal and pediatric intensive care setting, bedside cardiac ultrasound is often used to assess ventricular dimensions and function. Depending upon the underlying disease process, it is necessary to be able to evaluate the systolic and diastolic

Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular

The impact of Hnrnpl deficiency on transcriptional patterns of developing muscle cells

FEBS Open Bio, EarlyView.
We performed nanopore whole‐transcriptome sequencing comparing RNA from Hnrnpl‐knockdown versus control C2C12 myoblasts to investigate the contributions of Hnrnpl to muscle development. Our results indicate that Hnrnpl regulates the expression of genes involved with Notch signaling and skeletal muscle, particularly splicing patterns of specific muscle ...

Mechanisms mediating muscle metaboreflex control of cardiac output during exercise: Impaired regulation in heart failure

Experimental Physiology
The ability to increase cardiac output during dynamic exercise is paramount for the ability to maintain workload performance. Reflex control of the cardiovascular system during exercise is complex and multifaceted involving multiple feedforward and ...

A exposição crônica à fumaça do cigarro resulta em remodelação cardíaca e prejuízo da função ventricular em ratos Chronic cigarette smoke exposure results in cardiac remodeling and impaired ventricular function in rats

Arquivos Brasileiros de Cardiologia, 2005
OBJETIVO: Determinar as alterações cardíacas estruturais e funcionais causadas pela exposição à fumaça do cigarro em ratos. MÉTODOS: Os animais foram aleatoriamente distribuídos em dois grupos: fumante (F), composto por 10 animais, expostos à fumaça do ...

Autonomic regulation therapy to enhance myocardial function in heart failure patients: the ANTHEM-HFpEF study. [PDF]

, 2017
BackgroundApproximately half of the patients presenting with new-onset heart failure (HF) have HF with preserved left ventricular ejection fraction (HFpEF) and HF with mid-range left ventricular ejection fraction (HFmrEF).

Dietary nitrate and nitrite protect against doxorubicin‐induced cardiac fibrosis and oxidative protein damage in tumor‐bearing mice

FEBS Open Bio, EarlyView.
Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

Assessment of Myocardial Fibrosis in Marfan Syndrome Using Cardiac Magnetic Resonance Imaging

Molecular Genetics & Genomic Medicine
Background Impaired myocardial function and arrhythmia are important manifestations of Marfan syndrome (MFS). Studies assessing myocardial fibrosis in relation to these manifestations are scarce. Methods This cross‐sectional, single‐center study assessed

Analysis of left ventricular behaviour in diastole by means of finite element method [PDF]

, 1979
The human left ventricle in diastole can be modelled as a passive structure with incremental internal pressure change being considered as the load. Recent developments in engineering stress analysis provide techniques for predicting the behaviour of ...

Analysis of ventricular function by CT [PDF]

Journal of Cardiovascular Computed Tomography, 2015
The assessment of ventricular function, cardiac chamber dimensions, and ventricular mass is fundamental for clinical diagnosis, risk assessment, therapeutic decisions, and prognosis in patients with cardiac disease. Although cardiac CT is a noninvasive imaging technique often used for the assessment of coronary artery disease, it can also be used to ...
