Background: Coronary Artery Bypass Graft (CABG) surgery is associated
with several complications. Balance disorders have been reported in patients.
The impairments were associated with fall-related injuries and increase the
possibility of morbidity, mortality, and healthcare costs. The present study
aimed to compare postural balance before and after CABG surgery in patients
with established coronary artery disease.
Methods: This cross-sectional study was conducted on 87 patients aged 45-65
years who had undergone CABG surgery through the great saphenous vein.
Participants were enrolled into the study by convenience sampling. To assess
static balance, individuals were asked to perform the Single Leg Stance Test
(SLST). In addition, dynamic balance was measured by the Y-balance test, and
the Functional Reach Test (FRT) was conducted before and after CABG surgery.
These clinical tests were performed during the week before surgery and repeated
one month after that. Paired t-test was used to compare the Y-balance scores,
and Wilcoxon test was used to compare the mean values of other outcomes
before and after CABG surgery. A level of P<0.05 was considered statistically
Results: The results revealed a significant decrease in static and dynamic balance
after CABG surgery (P<0.001). A significant reduction was also observed in the
mean FRT scores in the postoperative period (P<0.001).
Conclusion: CABG surgery through the great saphenous vein influenced
balance in patients with coronary artery disease.
