Abstract
Background: The 6-minute walking test is a commonly easy test that does not need advanced
training. It is used for evaluating the functional status and exercise tolerance of patients with heart
diseases. It provides consistent information about the patient’s daily activity, the effect of
treatment, and the prognosis. Aim: To evaluate the effect of an early six-minute walking test
(6MWT) post coronary artery bypass graft on walking tolerance and physiological parameters.
Setting: This study was conducted at the cardiothoracic intensive care unit (ICU) at Mansoura
University Hospital in Egypt. Method: A quasi-experimental design was utilized in this research. A
convenience sample of 60 adult patients who were scheduled for and underwent coronary artery
bypass graft was enrolled in this study. Data were collected using ‘physiological parameters and
six minutes walking test assessment tool’. It involved three parts: Part I: Participants'
demographic and health profile data, Part II: Physiological parameters, and six minutes walking
test observation checklist and Part III: Borg rating of perceived exertion (RPE) scale. Results: No
significant differences were noted (p=≤ 0.05) between the intervention and control groups regarding
gender, age, smoking status, and body mass index. However, there were significant differences
between the two groups concerning the length of stay on mechanical ventilation, the time of six
minute walking test after extubation, complaining from dyspnea and fatigue, and the number of rest
periods. Conclusion and Recommendations: The implementation of an early 6MWT post
coronary artery bypass grafting improved patients' physiological parameters and walking tolerance.
Therefore, nurses should attend a training program on the implementation of early 6MWT for post
operative patients in the cardiothoracic intensive care units. Additionally, the 6MWT guidelines
and standards should be available in all hospitals to facilitate and enhance the success of cardiac
rehabilitation programs.
