Noninvasive hemodynamic monitoring in heart failure: utilization of impedance cardiography.
The annual health care cost incurred by heart failure patients is about $56 billion, two thirds of which is spent on management of acutely decompensated patients. Hemodynamic evaluation is helpful for optimization of treatment, monitoring clinical outcomes, and overall prognostication of heart failure patients, but historically could only be obtained via costly invasive procedures that carry su...
متن کاملApplicability of Impedance Cardiography During Heart Failure Flare-Ups
BACKGROUND Heart failure (HF) accounts for about 5% of all causes of urgent hospital admissions, and the overall mortality of HF patients within 1 year after hospitalization is 17-45%. Transthoracic impedance cardiography (ICG) is a safe, non-invasive diagnostic technique that helps to detect various parameters that define different cardiac functions. The aim of this study was to investigate th...
متن کاملBiological variation of the cardiac index in patients with stable chronic heart failure: inert gas rebreathing compared with impedance cardiography†
AIMS In chronic heart failure (CHF), changes in cardiac function define the course of the disease. The cardiac index (CI) is the most adequate indicator of cardiac function. Interpretation of serial CI measurements, however, requires knowledge of the biological variation of CI. Because measurements of CI can be confounded by the clinical situation or the method applied, biological variation mig...
متن کاملPatients With and Without Congestive Heart Failure?
Background. Although changes in contractility are often accompanied by changes in relaxation, a mathematical model of ventricular coupling has not been described. A model we examined suggests a hyperbolic relation between measurements of contraction and relaxation. We thus tested the hypothesis that relatively load-independent measurements of contractility (end-systolic elastance [Eesl) and rel...
متن کاملImpedance Cardiography *
Objective: To evaluate the following: (1) the intramethod variability of impedance cardiography (ICG) cardiac output (CO) measurements via the latest generation monitor and thermodilution CO measurements (CO-TDs); (2) the intermethod comparison of ICG CO and CO-TD; and (3) comparisons of the intergeneration ICG CO equation to CO-TD, using the latest ICG CO equation, the ZMARC (CO-ICG), and the ...
