Differences between the Filling Velocities of the Left and Right Heart Ventricle in Racing Pigeons (Columba livia F. Domestica) and the Influence of Anesthesia with Isoflurane

Veterinary Sciences, 2019
The ventricular filling velocities during diastole and the influence of isoflurane anesthesia on these blood flow velocities of the racing pigeon (n = 43) are evaluated by pulsed-wave (PW) Doppler sonography. Sonographic examination demonstrates an early

Risk of Non‐Arteritic Anterior Ischemic Optic Neuropathy in Idiopathic Intracranial Hypertension Patients Treated with GLP‐1 Receptor Agonists

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) have demonstrated significant weight‐reducing effects and may offer benefits in idiopathic intracranial hypertension (IIH); however, recent concerns about the risk of non‐arteritic anterior ischemic optic neuropathy (NAION) have emerged.

Quantitative three-dimensional cardiovascular magnetic resonance myocardial perfusion imaging in systole and diastole [PDF]

, 2014
Background Two-dimensional (2D) perfusion cardiovascular magnetic resonance (CMR) remains limited by a lack of complete myocardial coverage. Three-dimensional (3D) perfusion CMR addresses this limitation and has recently been shown to be clinically ...

Current perspectives in diastolic dysfunction and diastolic heart failure [PDF]

Heart, 2006
Diastolic heart failure (HF) has emerged over the last two decades as a separate clinical entity. Approximately half of the patients presenting with symptoms of congestive HF exhibit a near normal left ventricular (LV) systolic function at rest, which is thought to be caused by a predominant abnormality in diastolic function. It is generally considered

Long‐Term Efficacy of Immunotherapy in Autoimmune Autonomic Ganglionopathy—A 10‐Year Follow Up Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune autonomic ganglionopathy (AAG) is a rare but potentially treatable cause of severe autonomic failure. Evidence guiding long‐term immunotherapy, treatment sequencing, and residual autonomic impairment is limited. We evaluated long‐term treatment response, residual autonomic dysfunction, and relapse patterns in patients with

Time related Characteristics of cardiac systole, diastole, baroreeeptor activity and inactivity during vagal stimulation and mild haemorrhage in the dog [PDF]

, 1990
The duration of cardiac systole and diastole in each individual cardiac cycle were measured from aortic pressure curves during vagal stimulation and mild haemorrhage with simultaneous recording of aortic baroreceptor single fibre nerve activity.

Cerebral arterial flow dynamics during systole and diastole phases in young and older healthy adults [PDF]

, 2023
Background Since arterial flow is the leading actor in neuro-fluids flow dynamics, it might be interesting to assess whether it is meaningful to study the arterial flow waveform in more detail and whether this provides new important information.

Integrating Time‐Adjusted Imaging Instability Into Functional Outcome Prediction After Intracerebral Hemorrhage: Development and Validation of the HAGIV Score

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Early risk stratification may support clinical decision‐making in spontaneous intracerebral hemorrhage (ICH). We aimed to develop and internally validate HAGIV, a score integrating frequency of imaging markers (FIM), a time‐adjusted non‐contrast computed tomography (CT) metric of hematoma expansion, with established predictors for 90‐

Left ventricular diastolic dysfunction: Early diastolic relaxation and late diastolic compliance

Journal of the American College of Cardiology, 1989
The fundamental importance of cardiac filling in regulating performance of the heart was recognized by Starling (I) early in this century. Development of comprehensive ventricular function curves by Sarnoff and others (la,2) beginning in the 1950s focused attention on the role of ventricular compliance in influencing cardiac pump performance by ...
