ABSTRACT

A descriptive, longitudinal and prospective study of 36 patients of the male sex with ischemic heart disease was carried out. They were surgically treated by means of corrective surgery without extracorporeal circulation in the Territorial Center of Cardiovascular Surgery in Santiago de Cuba, during the first quarter of 2010, in order to identify the modifications of the impedance vector because of volume changes in body water due to surgical stress in comparison with a reference population, for which the electric bioimpedance method was used at 50 kHz. In the series significant differences in the highest axis of the tolerance ellipses were seen (associated to the hydration state) and in the smallest axis (associated to structure changes), and the distribution of water was significantly different between the reference population and the patients in the preoperative and postoperative conditions. It was concluded that the method of the vectorial analysis through bioimpedance is useful to detect the volume modifications of the body water caused by surgical stress.
