Scapular renal cell carcinoma metastasis as a cause of high-output heart failure: a case report

open access: yesBMC Cardiovascular Disorders, 2022
Background High-output heart failure is a rare condition that occurs when the heart is unable to respond to a sustained increase in blood demand. On echocardiography, a cardiac index of > 4 L/min/m2 (or 6 L/min) is a clear indicator of this disorder. The

A staggered-in-time and non-conforming-in-space numerical framework for realistic cardiac electrophysiology outputs [PDF]

open access: yesarXiv, 2023
Computer-based simulations of non-invasive cardiac electrical outputs, such as electrocardiograms and body surface potential maps, usually entail severe computational costs due to the need of capturing fine-scale processes and to the complexity of the heart-torso morphology. In this work, we model cardiac electrical outputs by employing a coupled model

CARDIAC OUTPUT COMPUTATION

open access: yesBritish Journal of Anaesthesia, 1970
SUMMARY A comparatively simple mathematical expression has been devised for the computation of the area under the cardiac output curve which is easy to use, quick to give a result, and yet is comparable in accuracy to other methods of determining cardiac output when the dye dilution technique is used.

Early metastasis is characterized by Gr1+ cell dysregulation and is inhibited by immunomodulatory nanoparticles

open access: yesMolecular Oncology, EarlyView.
Breast cancer metastasis is associated with myeloid cell dysregulation and the lung‐specific accumulation of tumor‐supportive Gr1+ cells. Gr1+ cells support metastasis, in part, through a CHI3L1‐mediated mechanism, which can be targeted and inhibited with cargo‐free, polymeric nanoparticles.

Predictors of low cardiac output in decompensated severe heart failure

open access: yesClinics, 2011
OBJECTIVE: To identify predictors of low cardiac output and mortality in decompensated heart failure. INTRODUCTION: Introduction: Patients with decompensated heart failure have a high mortality rate, especially those patients with low cardiac output ...
