Influence of Virtual Reality on Myocardial Revascularization

Study Overview
=================
Brief Summary
-----------------
Coronary artery disease is a dysfunction characterized by the narrowing of the coronary arteries in due to the accumulation of atheromatous plaques. The surgery of myocardial revascularization is a surgical procedure of choice performed in individuals with to improve symptoms and survival. Cardiovascular surgeries of this size in an extended time of rest after the procedure. Such immobility may have repercussions to the functionality of the individual. Thus, the early mobilization with the use of reality in the Intensive Care Units (ICU) emerges as a potential means of of complications in the postoperative period of cardiac surgery.

Detailed Description
-----------------
The study will be performed at the ICU coronary artery of the Hospital de Clínicas Gaspar Viana de Belém-Pará. 40 volunteers will participate in the study. preoperative period of myocardial revascularization. The oxidative stress (by the method called Optical Morphology by Oxidative Stress, using capillary blood drops), the modulation autonomic heart rate (with a Polar® model RS800CX) and motor function (through the Medical Research Council scale), before and after the application of protocol for cardiac rehabilitation with ergometer, virtual reality and ambulation. Volunteers will be randomized into a control group who receive the cardiac rehabilitation protocol from the hospital and the Early Mobilization Group, which will receive the cardiac rehabilitation protocol plus virtual reality training using Wii video game from Nintendo.
