Transitional Rehabilitation in CABG Patients

10. července 2021 aktualizováno: Michael J. Toth, Ph.D., University of Vermont

Novel Transitional Rehabilitation Care in Coronary Artery Bypass Graft (CABG) Patients

The goal of this research study is to understand whether an at-home exercise program started soon after CABG surgery, and continuing for 4 weeks following discharge from the hospital, can preserve or improve physical function.

Přehled studie

Detailní popis

Coronary artery bypass graft (CABG) surgery is a common surgical procedures and an important treatment option for coronary artery disease. The post-surgery period of rest and recovery is associated with cardiorespiratory and skeletal muscle deconditioning. The goal of this research study is to understand whether an at-home exercise program started soon after CABG surgery, and continuing for 4 weeks following discharge from the hospital, can serve as a bridge between surgery and the start of cardiac rehabilitation to preserve or improve physical function. Volunteers will be randomly assigned to receive neuromuscular electrical stimulation (NMES) of their quadriceps muscles or not to receive NMES (control group). Volunteers will be evaluated prior to CABG, upon discharge and 4 weeks Post-CABG surgery. Assessments will include measurements of physical function by the Short Physical Performance Battery, 6 min walk tests and body composition analysis, as well as assessment of subjective physical functional capacity and quality of life using the Medical Outcomes Short form 36. Additionally, accelerometry will be used to monitor weight-bearing physical activity during the 4 week treatment phase.

Popis opatření
Časové okno
Short Physical Performance Battery
Časové okno: 4 weeks
Short Physical Performance Battery is composed of three tasks assessing balance, gait speed, and ability to stand from a chair. Units on a scale for each domain range from of 0-4 for a total score of 0 to 12, with a higher score indicating better physical function.

Časové okno
6 Minute Walk Distance
Časové okno: 4 weeks
6 MW was developed to assess cardiopulmonary fitness in patients with lung and cardiac disease, and has been validated in cardiac surgery patients. It assesses the distance that a patient can walk in 6 minutes time around a standard course.

Medical Outcomes Short Form 36 - Physical Function
Časové okno: Hospital discharge and 4-weeks post-discharge
The Medical Outcomes Short Form 36 is a questionnaire that assesses self-reported health and physical functional status. There are 36 questions that reflect eight sub-domains of health included in this questionnaire. Scores for each domain represent weighted sums of the questions in each sub-domain. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. This sub-domain focused on limitations in physical function due to health problems. Lower scores represent more physical function disability, while higher scores represent less disability.

Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. This sub-domain focused on limitations in usual role activities because of physical health problems. Lower scores represent more disability, while higher scores represent less disability.

Physical Activity
Časové okno: Daily from discharge to 4-week post-discharge evaluation
Physical activity was measured throughout the intervention in control and treatment groups and data. Data were analyzed by regression analysis to obtain the best fit line for the data and to compute a slope of the change in step count with day post-discharge to examine whether groups differed in their rate of recovery of weight-bearing activity (ie, walking).
