Bioreactance is a reliable method for estimating cardiac output at rest and during exercise [PDF]

, 2015
Background: Bioreactance is a novel noninvasive method for cardiac output measurement that involves analysis of blood flow-dependent changes in phase shifts of electrical currents applied across the thorax.

Changes in cardiac output with hemodialysis relate to net volume balance and to inferior vena cava ultrasound collapsibility in critically ill patients

Renal Failure, 2020
Cardiac output may increase after volume administration with relative intravascular volume depletion, or after ultrafiltration (UF) with relative intravascular volume overload. Assessing relative intravascular volume using respiratory/ventilatory changes

A cortical potential reflecting cardiac function [PDF]

, 2007
Emotional trauma and psychological stress can precipitate cardiac arrhythmia and sudden death through arrhythmogenic effects of efferent sympathetic drive. Patients with preexisting heart disease are particularly at risk.

Comparison of continuous cardiac output monitoring derived from regional impedance cardiography with continuous thermodilution technique in cardiac surgical patients

Annals of Cardiac Anaesthesia, 2020
Background: Cardiac output (CO) assessment is a corner stone in advanced haemodynamic management, especially in critical ill patients. The present study was conducted to validate cardiac index and cardiac output by NICaS™ with the thermodilution ...

The normal ranges of cardiovascular parameters measured using the ultrasonic cardiac output monitor [PDF]

, 2017
The ultrasonic cardiac output monitor (USCOM) is a noninvasive transcutaneous continuous wave Doppler method for assessing hemodynamics. There are no published reference ranges for normal values in adults (aged 18– 60 years) for this device.

Videodensitometric Methods for Cardiac Output Measurements

EURASIP Journal on Advances in Signal Processing, 2003
Cardiac output is often measured by indicator dilution techniques, usually based on dye or cold saline injections. Developments of more stable ultrasound contrast agents (UCA) are leading to new noninvasive indicator dilution methods.

The aorta in humans and African great apes, and cardiac output and metabolic levels in human evolution

Scientific Reports, 2023
Humans have a larger energy budget than great apes, allowing the combination of the metabolically expensive traits that define our life history. This budget is ultimately related to the cardiac output, the product of the blood pumped from the ventricle ...

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Apolipoprotein E Genotype Modifies the Association Between Cardiac Output and Cognition in Older Adults

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Subtle reductions in cardiac output relate to lower cerebral blood flow, especially in regions where Alzheimer's disease pathology first develops.
