Abstract

Impedance cardiography (ICG) represents a non-invasive method for hemodynamic assessment in a beat-to-beat basis. Since its introduction more than forty years ago, a renewed interest in the use of this technique during the last decade has been noticed, mainly as a result of a series of clinical studies showing its precision in the estimation of stroke volume either against invasive gold standard (i.e. ther- modilution) or against non-invasive reference methods (i.e. echocardiography). On the other hand, ICG has demonstrated to be useful for the management of heart failure patients and for the diagnostic and therapeutic approach to hypertension, which currently constitute two of the major applications of ICG. In heart failure patients, changes in thoracic fl uid content and cardiac output tracked by ICG have shown to be predictors of acute decompensation even weeks before respiratory symptoms appear; also allowing identifi cation of a cardiac vs. respiratory origin of dyspnea when physical examination and laboratory tests are not conclusive. In the particular case of patients with uncontrolled or severe hypertension, ICG makes possible a better characterization of hypertensive phenotype leading to a more specifi c choice of pharmacological agents to treat the primary hemodynamic alteration (i.e elevated peripheral resistance vs. elevated cardiac output). The present review, provides a review of the biophysical principles of ICG and its precision in measuring stroke volume and present a critical assessment of the literature supporting its clinical application in the management of heart failure and arterial hypertension.
