Feasibility and safety of high-dose adenosine perfusion cardiovascular magnetic resonance

open access: yesJournal of Cardiovascular Magnetic Resonance, 2010
Introduction Adenosine is the most widely used vasodilator stress agent for Cardiovascular Magnetic Resonance (CMR) perfusion studies. With the standard dose of 140 mcg/kg/min some patients fail to demonstrate characteristic haemodynamic changes: a ...

Exercise Right Heart Catheterisation in Cardiovascular Diseases: A Guide to Interpretation and Considerations in the Management of Valvular Heart Disease

open access: yesInterventional Cardiology: Reviews, Research, Resources, 2021
The use of exercise right heart catheterisation for the assessment of cardiovascular diseases has regained attention recently. Understanding physiologic haemodynamic exercise responses is key for the identification of abnormal haemodynamic patterns ...

Life events and hemodynamic stress reactivity in the middle-aged and elderly [PDF]

open access: yes, 2005
Recent versions of the reactivity hypothesis, which consider it to be the product of stress exposure and exaggerated haemodynamic reactions to stress that confers cardiovascular disease risk, assume that reactivity is independent of the experience of ...

Ageing alters the severity of Sunitinib-induced cardiotoxicity: Investigating the mitogen activated kinase kinase 7 pathway association [PDF]

open access: yes, 2019
Anti-cancer drug Sunitinib is linked to adverse cardiovascular events, which have shown to involve mitogen activated kinase kinase 7 (MKK7) pathway. Sunitinib-induced cardiotoxicity in 3, 12 and 24 months old male Sprague-Dawley rats and MKK7 expression ...

Pulmonary vascular responses to exercise: a haemodynamic observation [PDF]

open access: yesEuropean Respiratory Journal, 2012
Exercise testing provides additional information over resting variables and is a standard of care in the assessment of coronary artery disease with less subsequent cardiovascular events. In pulmonary hypertension (PH), right ventricular function is clearly an important determinant of survival. However, right ventricular impairment is currently assessed

Functional Optical Topography Analysis Using Statistical Parametric Mapping (SPM) Methodology with and without Physiological Confounds [PDF]

open access: yes, 2010
Functional optical topography (OT) measures the changes in oxygenated and deoxygenated hemoglobin (HbO(2), HHb) across multiple brain sites which occur in response to neuronal activation of the cerebral cortex.

Rate-responsive pacing regulated by cardiac haemodynamics

open access: yesEuropace, 2005
Trans-valvular impedance (TVI) recording has been proposed for the assessment of cardiac haemodynamics, assuming an inverse relationship between TVI and ventricular volume. We checked whether the TVI sensor can drive the rate-responsive function of a cardiac pacemaker following changes in the inotropic regulation of the heart.An external DDD-R ...

Pitch Processing Can Indicate Cognitive Alterations in Chronic Liver Disease: An fNIRS Study

open access: yesFrontiers in Human Neuroscience, 2020
Early detection and evaluation of cognitive alteration in chronic liver disease is important for predicting the subsequent development of hepatic encephalopathy.

Effects of Low Dose Dexmedetomidine Infusion on Intraoperative Haemodynamic Stress Response in Patients Undergoing Oral Oncological Surgeries: A Randomised Control Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2020
Introduction: Maintaining stable haemodynamics throughout oral and maxillofacial surgeries helps to decrease intraoperative bleeding and thus improves the surgical field avoiding unnecessary damage to vital structures and tissues.

Comparing the Effect of Preoxygenation using High-flow Nasal Oxygen and the Tight Facemask Technique during Rapid Sequence Induction in Abdominal Surgeries: A Research Protocol [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Introduction: Preoxygenation is a critical step during Rapid Sequence Induction (RSI) to prevent hypoxemia during the apnoeic phase, particularly in patients undergoing abdominal surgeries who are at higher risk due to full stomachs, elevated ...
