Tissue Doppler study in the diagnosis of functional disorders of the myocardium in patients with chronic heart failure

open access: yesRUDN Journal of Medicine, 2010
The article presents a comparative analysis of standard echocardiography and tissue Doppler method Rings atrioventricular valves in patients with chronic heart failure with a view to early diagnosis of functional disorders of the myocardium.

Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

open access: yesArtificial Organs, EarlyView.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

Project Sickle Cure: A Prospective, International Observational Study of Hematopoietic Cell Transplantation for Sickle Cell Disease

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic and life‐limiting hemoglobin and systemic vascular disease. While over 1000 people have undergone hematopoietic cell transplantation (HCT) over the last 40 years, long‐term disease‐specific and health‐related quality of life data are lacking.

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

open access: yesEquine Veterinary Education, EarlyView.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

open access: yesThe FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Refining Residual Ischemic Stroke Risk in Anticoagulated Atrial Fibrillation Using Index Outpatient LA Diameter: The CHA2DS2‐VALa Score

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
In anticoagulated atrial fibrillation, residual ischemic stroke risk persists despite guideline‐directed therapy. In this single‐center cohort, an enlarged index outpatient left atrial diameter independently predicted stroke and improved risk stratification when added to CHA2DS2‐VA (CHA2DS2‐VALa), supporting a simple, clinically implementable ...

Diastolic Dysfunction and Doppler Echocardiography

open access: yesJournal of the American College of Cardiology, 2005
The recent review by Maurer et al. ([1][1]) on diastolic dysfunction was a welcome read. I concur completely with their observations that “have led us to fundamentally question whether diastolic dysfunction is the underlying pathologic mechanism of the heart failure syndrome in all ...

Changes in hemodynamics of pulmonary artery using Flowire in a canine model of acute pulmonary thromboembolism

open access: yesAnimal Models and Experimental Medicine
Background Pulmonary hypertension (PH) is a life‐threatening condition that can be triggered by pulmonary thromboembolism (PTE), which causes abrupt increases in pulmonary artery pressure and resistance.

Pre‐anaesthetic risk assessment and management of dogs with myxomatous mitral valve disease: a spectrum of care narrative review

open access: yesJournal of Small Animal Practice, EarlyView.
Myxomatous mitral valve disease, an acquired valvular degeneration, is the most common cardiac disorder in dogs, affecting approximately 10% of dogs in primary care veterinary practice. Dogs with myxomatous mitral valve disease frequently require anaesthesia for routine procedures.

Cardiovascular Responses to Natural and Auditory Evoked Slow Waves Predict Post‐Sleep Cardiac Function

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT The importance of sleep as a key component of cardiovascular health has been increasingly recognized. Our previous research demonstrated that auditory‐enhanced slow waves increase cardiac function, but the underlying mechanisms behind these beneficial effects remain uncertain. In this study, we examined the influence of two types of slow waves
