Bedside ultrasound to assess acute central venous pressure change during treatment of decompensated heart failure

International Journal of Cardiology: Heart & Vasculature, 2022
Background: Accurate volume status assessment is crucial for the treatment of acute decompensated heart failure (ADHF). Volume status assessment by physical exam is often inaccurate, necessitating invasive measurement with right heart catheterization ...

Magnetocardiography combined with machine learning for pulmonary hypertension detection and improved short‐term risk assessment

Interdisciplinary Medicine, EarlyView.
Magnetocardiography (MCG) enables non‐invasive mapping of cardiac magnetic fields. In this study, an MCG‐based machine learning model detects pulmonary hypertension with robust performance. Furthermore, MCG features may improve the accuracy of short‐term risk assessment.

Bedside Assessment of Left Ventricular Function in the Respiratory Intensive Care Unit [PDF]

, 1973
The measurement of the central venous pressure is a widely used technique for gaining information concerning the relationship of the blood volume as it relates to cardiac function. This concept has been widely popularized, and the central venous pressure

Larger pulmonary artery to ascending aorta ratios are associated with decreased survival of patients undergoing pulmonary endarterectomyCentral MessagePerspective

JTCVS Open, 2022
Objectives: The ratio of pulmonary artery (PA) and ascending aorta (AA) diameters has recently been shown to be a useful indicator for disease severity and predictor of outcome in patients with pulmonary hypertension and heart failure.

Myocardial oxygen consumption, myocardial efficiency, and mechanical efficiency: A review across pathologic and physiologic states

Physiological Reports, Volume 14, Issue 10, May 2026.
Abstract Myocardial work and oxygen consumption (MVO2) are tightly coupled. The patient's physiological state, presence of disease, heart rate, and microvascular control of oxygen delivery all combine to maintain this relationship. The myocardial efficiency (MyoEff) of the heart is determined by the ratio of stroke‐work (SW) divided by MVO2, whereas ...

Cardiac power output accurately reflects external cardiac work over a wide range of inotropic states in pigs [PDF]

, 2019
BACKGROUND: Cardiac power output (CPO), derived from the product of cardiac output and mean aortic pressure, is an important yet underexploited parameter for hemodynamic monitoring of critically ill patients in the intensive-care unit (ICU).
