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

The Journal of Physiology, EarlyView.
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 ...

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 287-300, August 1, 2026.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

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

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

The Impact of Cardiac Output Methods on the Classification of Pulmonary Hypertension

Pulmonary Circulation
Cardiac output is essential to calculate pulmonary vascular resistance (PVR) and classify pulmonary hypertension (PH). Recent evidence has shown a lower agreement between thermodilution (COTD) and direct Fick (CODF) methods than historically estimated ...

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 ...

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

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).
