Exercise-based Cardiac Rehabilitation Program on Hospitalized Heart Failure Patients Submitted to Cardiac Transplantation

Not Applicable
Conditions

Other: Cycle ergometer exercise protocol
Registration Number
NCT03506737
Lead Sponsor
Federal University of São Paulo
Brief Summary

Objective: To evaluate the effects of an early-based cardiac rehabilitation program on the functional capacity, inspiratory muscular strength and clinical outcomes in hospitalized heart failure patients before and after heart transplantation. Method: 30 hospitalized heart failure patients awaiting cardiac transplantation will be selected and randomized in 2 groups: conventional group (n = 15) - conventional exercise protocol: breathing exercises and global active exercises of upper and lower limbs in the sitting position; and Intervention group (n = 15) - cycle ergometer exercise protocol: each session consists of cycling on a stationary bicycle in the seated position for 20 minutes. In both groups, the exercise protocols will be applied twice a day until the hospital discharge, always supervised by a physiotherapist and a doctor. The evaluation procedures in all patients of the research will be: functional capacity measured by the 6 minute walk test and inspiratory muscle strength measured by manovacuometry. Evaluations will be repeated in 3 distinct moments: after 24h of hospital admission and/or clinical stabilization; before transplantation and after transplantation in hospital discharge.

Primary Outcome Measures
NameTimeMethod
Six-minute walk test to measure functional capacity changeAfter 24 hours of hospital admission or clinical stabilization; before transplantation (after 4 weeks of rehabilitation program) and in hospital discharge (after 4 weeks of transplantation).

According to the baseline distance walked, we will evaluate the improvement in functional capacity after the period of the rehabilitation programs

Respiratory muscle strengthAfter 24 hours of hospital admission or clinical stabilization; before transplantation (after 4 weeks of rehabilitation program) and in hospital discharge (after 4 weeks of transplantation)

By manovacuometry, assessing the change in inspiratory muscle pressure and expiratory muscle pressure

Secondary Outcome Measures
NameTimeMethod
Invasive mechanical ventilationFirst day after transplantation.

Duration of invasive mechanical ventilation will be recorded after cardiac transplantation.

Duration of intensive care unit stayIn hospital discharge (after 4 weeks of transplantation).

Duration of stay in intensive care unit (in days) after transplantation will be recorded.

Hospitalization stayIn hospital discharge (after 4 weeks of transplantation).

Duration of stay in the hospital (in days) will be recorded.
