Description
Coronary artery disease (CAD) is a condition characterized by impaired cardiac function due to a reduced blood supply
to the myocardial tissue, resulting from narrowing or obstructing of the coronary arteries. This condition can negatively
impact the physical, psychological, and social dimensions of the patient’s life, often leading to a decline in maximal
oxygen consumption (VO2max) and perceived comfort. One solution for increasing the decreased VO2max is cardiac
rehabilitation. Cardiac rehabilitation is an effective preventive and recovery intervention that includes assessments of
VO2max, and the effects of the incremental shuttle walk test (ISWT) on the VO2max and comfort of CAD patients. This
is a quasi-experiment with a pre-post control group design. Consecutive sampling was used to recruit 60 respondents,
who were then divided into a control and an intervention group, with 30 respondents in each group. VO2max was
measured using the distance achieved in the ISWT, and comfort was assessed using the Shortened General Comfort
Questionnaire (SGCQ). Data were analyzed using a paired t test to determine whether the mean pretreatment VO2max
and comfort levels significantly changed after the treatment. VO2max and comfort showed significant improvements
after the ISWT (p = 0.001 for both variables), confirming the effectiveness of ISWT in CAD patients undergoing phase
3 cardiac rehabilitation. Therefore, ISWT should be considered an integral part of cardiac rehabilitation for the
management of CAD patients after hospital discharge.
