Materials and Methods: This quasi-experimental study was carried out on 34 patients in Tabriz Shahid Madani hospital from 1 March to the end of July 2019. It is noteworthy that participants were selected based on a random sampling method. The experimental group, namely, the exercise group (n=17) did cardiovascular exercises for 40 minutes the day before the surgery. However, the other group received physiotherapy for each leg for 15 minutes in addition to cardiovascular exercise. Then, DVT diagnosis blood tests, clinical examinations, and Doppler sonography were performed and recorded in all participants’ portfolios. The obtained data were analyzed using SPSS software, and the SPSS tests included Kolmogorov-Smirnov, paired t test, and independent t-test at the significance level of 0.05.

Results: The results of intra-group DVT and blood tests before and after the intervention revealed a statistically significant difference in terms of complete blood count, hemoglobin, hematocrit (P ≤ 0.05). However, no statistically significant differences were reported considering the other variables (P ≥ 0.11). Finally, in the case of inter-group variations, a comparison of the results of the two groups represented no statistically significant difference in any of the studied variables (P ≥ 0.15).

Conclusions: In general, a light exercise session either with or without physiotherapy did not have any positive effects on DVT prevention in postmenopausal women in need of CABG.
