| Research Abstract |
We investigated whether the amount of in-hospital physical activity after cardiac surgery predicts the major adverse cardiovascular events (MACE) within one-year follow-up period. One hundred and thirty three patients who underwent cardiac surgery were included in this study. The average number of steps before discharge was 2,460 ± 1,549. Out of 133 patients, there were 16 cases (12.0%) of re-hospitalization due to MACE during one-year follow-up period. The cut-off value that predicts the occurrence of MACE on the ROC curve was 1,308 steps (Area under the curve: 0.7836, p < 0.001, Sensitivity: 0.814, Specificity: 0.733). Cox proportional hazards analysis revealed that the strongest predictor of MACE as a condition in which patients could barely make 1,308 steps or more before discharge (hazard ratio: 7.58; 95% CI: 2.04-28.22). The amount of in-hospital physical activity could be a risk factor of MACE within one-year follow-up period after cardiac surgery.
