| COPD, n (%) | 5 (10.9) | 7 (20.0) | 0.252 |
| Renal dysfunction, n (%) | 5 (10.9) | 1 (2.9) | 0.173 |
| Hypertension, n (%) | 25 (56.8) | 17 (48.6) | 0.466 |

| Time to mobilization (mean±SD) | 49.4±11.5 | 14.2±8.2 | 0.977 |
| ICU stay (mean±SD) | 69.5±20.5 | 63.9±21.8 | 0.240 |
| Hospital stay (mean±SD) | 155.0±11.7 | 144.6±31.0 | 0.042* |
| Blood transfusion, n (%) | 23 (50.0) | 12 (34.3) | 0.157 |
| Atrial and ventricular arrhythmias, n (%) | 1 (2.2) | 3 (8.6) | 0.188 |
| New onset renal dysfunction, n (%) | 2 (4.3) | 0 (0.0) | 0.212 |
| Gastrointestinal complications, n (%) | 1 (2.2) | 0 (0.0) | 0.380 |
| Respiratory complications, n (%) | 0 (0.0) | 1 (2.9) | 0.249 |
*P<0.05, statistically significant. Demographic profiles of the control group and study group were comparable. In postoperative parameters, only hospital stay is statistically significant. EF: Ejection fraction, ICU: Intensive Care Unit, BMI: Body mass index, DM: Diabetes mellitus, COPD: Chronic obstructive pulmonary disease, PVD: Peripheral vascular disease, SD: Standard deviation
