Abstract

Objective: To evaluate the safety and effectiveness of the cardiac rehabilitation (CR) program after open-heart surgery (OHS) in both inpatient and outpatient phases.

Methods: This is a controlled clinical trial research. 67 patients, who underwent OHS, agreed to participate in the study at the Rehabilitation Department of Military Hospital 175, from 12/2023 to 09/2024. They were divided into two groups: 32 patients in the CRP group (intervention group) and 35 patients in the non-CRP group (control group). The CR program in the inpatient phase included peri-operavtive respiratory and limb mobility exercises until hospital discharge, the outpatient phase included individualized endurance exercise using a cycle ergometer, upper and lower limb strength excercises, lasting 60 minutes per session, 3–5 sessions per week, for six weeks. A total of 50 patients (25 in the intervention group and 25 in the control group) completed the procedure.

Results: In the inpatient phase, CR was safe for patients after OHS, with a 2% incidence of respiratory complications, the average duration of ICU and postoperative hospitalization was 3,8 and 10,9 days respectively. In the outpatient phase, patients in the intervention group showed an improvement in exercise capacity, with an increase by 13.5% in VO2 max from 17.16 ± 3.77 to 19.48 ± 4.15 ml/kg/min (p<0.01) and an 11% increase in METs from 5.41 ± 1.41 to 6.00 ± 1.55 (p><0.01). In contrast, patients in the control group showed no significant improvement in VO2 max, with an increase of 3.2% only (p>0.05), and an insignificant 6.3% increase in METs (p>0.05). In both groups, the 6-minute walking test distance significantly increased, with a gain of 35.6m in the intervention group and 34.8m in the control group (p<0.05)

Conclusion: The CR program after OHS is safe and effective, the incidence of postoperative complications is low, enhancing exercise capacity and improving the quality of life.
