Adaptations to iron deficiency: cardiac functional responsiveness to norepinephrine, arterial remodeling, and the effect of beta-blockade on cardiac hypertrophy. [PDF]

, 2002
BackgroundIron deficiency (ID) results in ventricular hypertrophy, believed to involve sympathetic stimulation. We hypothesized that with ID 1) intravenous norepinephrine would alter heart rate (HR) and contractility, 2) abdominal aorta would be larger ...

Extracorporeal support for patients with acute respiratory distress syndrome. [PDF]

, 2014
Extracorporeal membrane oxygen (ECMO) has been used for many years in patients with life-threatening hypoxaemia and/or hypercarbia. While early trials demonstrated that it was associated with poor outcomes and extensive haemorrhage, the technique has ...

Synchronous quantification of arterial, venous, and cerebrospinal fluid flow dynamics using real-time phase-contrast MRI

Fluids and Barriers of the CNS
Background Neurofluid flow dynamics are frequently studied from asynchronous blood and CSF flow measurements from real-time imaging using separate phase contrast (PC) MRI scans.

Cerebral blood flow during cardiopulmonary bypass in pediatric cardiac surgery: the role of transcranial Doppler – a systematic review of the literature

Cardiovascular Ultrasound, 2006
Background Transcranial Doppler Ultrasound (TCD) is a sensitive, real time tool for monitoring cerebral blood flow velocity (CBFV). This technique is fast, accurate, reproducible and noninvasive.

Effect of Outflow Tract Banding on Embryonic Cardiac Hemodynamics

Journal of Cardiovascular Development and Disease, 2015
We analyzed heart wall motion and blood flow dynamics in chicken embryos using in vivo optical coherence tomography (OCT) imaging and computational fluid dynamics (CFD) embryo-specific modeling. We focused on the heart outflow tract (OFT) region of day 3

Source, triggers and clinical implications of hyperlactemia in patients undergoing mitral valve surgery using Custodiol cardioplegia [PDF]

, 2013
Postoperative blood hyperlactaemia is an indicator of organ anaerobic metabolism and is associated with morbidity after cardiac surgery. This prospective study aims to explore the source, triggers and clinical implications for hyperlactaemia in patients ...

BLOOD FLOW DISTRIBUTION IN ESSENTIAL HYPERTENSION

Российский кардиологический журнал, 2002
128 patients of essential hypertension were examined with the help of ultrasound Doppler to measure speed of blood flow and vessels diameter on the heart, aorta, cubital arterial level.
