On the adaptive significance of group III/IV muscle afferent feedback for the cardiovascular response during sustained locomotion in humans

The Journal of Physiology, Volume 604, Issue 17, Page 7112-7124, 1 September 2026.
Abstract figure legend Group III/IV leg muscle afferent feedback has previously been recognized as an important determinant of the cardiovascular response to exercise lasting <5 min. Here we demonstrate that the activity of these neurons is crucial in regulating central and peripheral haemodynamic responses during steady state exercise of longer ...

Comparison of transthoracic electrical bioimpedance cardiac output measurement with thermodilution method in post coronary artery bypass graft patients

Annals of Cardiac Anaesthesia, 2011
Transthoracic electrical bioimpedance (TEB) has been proposed as a non-invasive, continuous, and cost-effective method of cardiac output (CO) measurement. In this prospective, non-randomized, clinical study, we measured CO with NICOMON (Larsen and Toubro

Use of thermodilution cardiac output overestimates diagnoses of exercise-induced pulmonary hypertension

Pulmonary Circulation, 2017
Two new definitions of exercise-induced pulmonary hypertension (EIPH) have emerged. Both rely on measuring cardiac output (CO), yet this remains unstandardized. In our cohort of patients undergoing invasive cardiopulmonary exercise testing, we found that

Measurement of cardiac index by transpulmonary thermodilution using an implanted central venous access port: a prospective study in patients scheduled for oncologic high-risk surgery. [PDF]

PLoS ONE, 2014
BACKGROUND:Transpulmonary thermodilution allows the measurement of cardiac index for high risk surgical patients. Oncologic patients often have a central venous access (port-a-catheter) for chronic treatment.

Impella‐Assisted High‐Risk Percutaneous Coronary Intervention in Cardiogenic Shock With Low‐Flow, Low‐Gradient Aortic Stenosis and Multivessel Coronary Artery Disease: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Patients with cardiogenic shock, low‐flow, low‐gradient aortic stenosis, and multivessel coronary artery disease who are ineligible for surgery present a major therapeutic challenge. Percutaneous mechanical circulatory support may facilitate revascularization in this high‐risk population. A 69‐year‐old man presented after a mechanical fall and

Post lung-transplant predictive value of thermodilution vs estimated Fick cardiac output measurement

JHLT Open
Background: Comparison of thermodilution (TD) and indirect Fick (iFick) methods of cardiac output (CO) measurement has not been well described in patients with World Health Organization (WHO) group 3 pulmonary hypertension (PH).

Assessment of Pulmonary Vascular Impedance in Patients With Severe Pulmonary Arterial Hypertension

Comprehensive Physiology, Volume 16, Issue 4, August 2026.
Pulmonary vascular impedance (PVZ) was calculated from clinical PA pressure and RVOT flow velocity profiles. Participants with increased pulmonary vascular resistance have increased PVZ, afterload, and diastolic stiffness. The characteristic impedance (ZC) to mean PA pressure relationship models the effect of proximal vasculature remodeling on ZC for a

Coronary Microvascular Dysfunction: Epidemiology, Pathophysiology, Diagnosis, and Treatment

MedComm, Volume 7, Issue 8, August 2026.
This visual summary illustrates the key aspects of coronary microvascular dysfunction (CMD) in angina with nonobstructive coronary artery disease (NOCAD), including epidemiology, pathophysiology (microvascular remodeling and endothelial dysfunction), the protective NRG‐1/ErbB signaling pathway, diagnostic methods, and both Western and traditional ...

Correction of Hemodynamic Disorders in the Complex Surgical Correction of Acquired Cardiac Valvular Defects

Общая реаниматология, 2011
Objective: to compare the efficiency of using the values of transpulmonary (PiCCO) and prepulmonary (Swan-Ganz catheter) thermodilution as guides to targeted therapy for hemodynamic disorders in the surgical correction of mixed cardiac valvular defects ...
