Effects a Rehabilitation Program in Patients With Left Ventricular Dysfunction After Coronary Artery Bypass Grafting

3 de mayo de 2016 actualizado por: Solange Guizilini, Federal University of São Paulo

Effects of Exercise Rehabilitation Program at Hospitalar Fase on Inflammatory Markers, Functional Capacity and Clinical Outcomes in Patients With Left Ventricular Dysfunction After Coronary Artery Bypass Grafting

This study aims to analyze effects of three types of cardiac rehabilitation protocol on fuctional capacity, inflammatory markers, pulmonary function and clinical outcomes after coronary artery bypass grafting (CABG) in patients with left ventricular disfunction. Patients will be randomized and allocated in three groups according to type of exercise protocol: 1. walk; 2. cycle; 3. functional electrical stimulation.

Descripción general del estudio

Descripción detallada

Several studies have been demonstrated beneficial effects of exercise to minimize impact of CABG. However, there is no consensus on what kind of exercise is safe and effective for patients with left ventricular dysfunction.

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: Walking exercise
Participants will be sumitted to progressive exercises and supervised by a physiotherapist, active-assisted to free active exercise in upper and lower limbs, stationary running and walking. The intensity of walk will be determined by the Borg's sujective effort perception scale - (modified from zero to 10). On first postoperative day, participants will perform exercises in supine position. From the second to the fifth postoperative day, they will perform progressive walking.

Experimental: Neuromuscular electrical stimulation
Participants will be sumitted to progressive exercises and supervised by a physiotherapist, active-assisted to free active exercise in upper and lower limbs. From the first to the fifth postoperative day, quadriceps and gastrocnemius muscles will be percutaneous stimulated with the following parameters: Synchronic mode, 50Hz, 400uS, time on 10s, time off 20s, intensity as tolerated by the patient.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Functional Capacity
Periodo de tiempo: Up to ten days after surgery, at hospital discharge.
Participants will be submitted to six minute walk test on preoperative period and sixth postoperative day (or before hospital discharge) to evaluate functional capacity. The test will be performed with a mobile device to measure metabolic response to exercise (Oxycon™ Mobile).
Up to ten days after surgery, at hospital discharge.

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Inflammatory markers
Periodo de tiempo: in-hospital postoperative period, up to ten days after surgery.
Blood sample will be collected to measure inflammatory markers (TNF-alpha and interleukins) and to compare exercise effects on inflammatory response after surgery.
in-hospital postoperative period, up to ten days after surgery.
