Contemporary Evidence and Practice on Right Heart Catheterization in Patients with Acute or Chronic Heart Failure

open access: yesDiagnostics
Heart failure (HF) has a global prevalence of 1–2%, and the incidence around the world is growing. The prevalence increases with age, from around 1% for those aged 10% for those aged 70 years or over.

Bisoprolol Delays Progression Towards Right Heart Failure in Experimental Pulmonary Hypertension [PDF]

open access: yes, 2012
Background— In pulmonary arterial hypertension (PH), sympathetic adrenergic activity is highly elevated. Sympathetic overactivity is a compensatory mechanism at first, but might be detrimental for cardiac function in the long run.

Predicting Heart Failure with Attention Learning Techniques Utilizing Cardiovascular Data [PDF]

open access: yesarXiv
Cardiovascular diseases (CVDs) encompass a group of disorders affecting the heart and blood vessels, including conditions such as coronary artery disease, heart failure, stroke, and hypertension. In cardiovascular diseases, heart failure is one of the main causes of death and also long-term suffering in patients worldwide. Prediction is one of the risk

Magnetic Field‐Assisted Conductive Nerve Guidance Conduit Enabling Peripheral Nerve Regeneration with Wireless Electrical Stimulation

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a conductive nerve guidance conduit integrated with wireless electrical stimulation through alternating magnetic fields, which induces currents and creates a supportive microenvironment for nerve regeneration. In vivo studies show that this approach significantly enhanced myelin restoration, gastrocnemius muscle regeneration ...

Geodesic-based Predictive Shape Modeling on Right Ventricles of Patients with Hypoplastic Left Heart Syndrome [PDF]

open access: yesarXiv
Hypoplastic left heart syndrome (HLHS) is a congenital defect in which right ventricle (RV) shape changes over time in response to altered loading conditions as adaptations to patient's single ventricle physiology. The RV shape can be considered as a co-indicator of the severity of underlying tricuspid valve (TV) regurgitation in HLHS, thus the ...
