Cardiac Rehabilitation Increases the Reliability of the 6-Minute Walk Test in Patients After Coronary Artery Bypass Graft Surgery

Background: Few data are available on the capacity for functional exercise after cardiac rehabilitation in patients who have undergone coronary artery bypass graft (CABG) surgery. The aim of this study was to determine the clinical and biochemical factors that affect the 6-minute walk test (6MWT) results in patients who have undergone CABG.Methods: Data were prospectively collected from 56 patients consecutively admitted at our hospital between January 2013 and May 2015 for a 3-month cardiac rehabilitation program. Data were analysed retrospectively up to 90 days after cardiac surgery. In addition to clinical and biochemical parameters, the functional capacity of patients was evaluated by an exercise 6-minute walking test and echocardiography. Functional capacity was evaluated at baseline and after three months of cardiac rehabilitation. Results: Before cardiac rehabilitation, the 6MWT values were negatively correlated with Body Mass Index (BMI) and abdominal and buttock diameters (r = -0.375, -0.386, and -0.370, respectively; P < .05), and were positively correlated with metabolic equivalent (MET) values (r = 0.493, P < .05). After cardiac rehabilitation, the 6MWT values were negatively correlated with body mass index (BMI) and abdominal and buttock diameters (r = -0.382, -0.274, and -0.405, respectively; P < .05) and were positively correlated with MET and VO2 max values (r = 0.456 and 0.573, respectively; P < 0.05). Before cardiac rehabilitation, VO2 max and FEV1/FEVC values were found as factors that significantly increased 6MWT values (P < .05). After cardiac rehabilitation, VO2 max values were found as factors that significantly increased 6MWT values (P < .05).Conclusion: Overall, in current clinical settings, cardiac rehabilitation increases the reliability of the 6MWT. Improvement in pulmonary function after cardiac rehabilitation reduces the impact of pulmonary function on 6MWT values. The functional capacity of patients may be more reliably determined by 6MWT after cardiac rehabilitation.

Objective: In this secondary analysis of data from the OPTICARE trial, we compared the effects of two behavioral interventions integrated into cardiac rehabilitation to standard rehabilitation with regard to functional capacity, fatigue, and participation in society. Design: This is a randomized controlled trial. Setting: This study was conducted in a cardiac rehabilitation setting. Subjects: A total of 740 patients with acute coronary syndrome were recruited for this study. Interventions: Patients were randomized to (1) three months of standard rehabilitation; (2) cardiac rehabilitation plus nine months after-care with face-to-face group lifestyle counseling; or (3) cardiac rehabilitation plus nine months after-care with individual lifestyle telephone counseling. Main measures: Functional capacity (6-minute walk test), fatigue (Fatigue Severity Scale), and participation in society (Utrecht Scale for Evaluation of Rehabilitation-Participation) were measured at randomization, 3, 12, and 18 months. Results: Additional face-to-face sessions resulted at 12 months in 12.49 m more on the 6-minute walk test compared to standard rehabilitation ( P = .041). This difference was no longer present at 18 months. Prevalence of fatigue decreased from 30.2% at baseline to 11.9% at 18 months compared to an improvement from 37.3% to 24.9% after standard rehabilitation (between-group difference: odds ratio = 0.47; P = .010). The additional improvements in functional capacity seemed to be mediated by increases in daily physical activity. No mediating effects were found for fatigue. No additional improvements were seen for participation in society. Additional telephonic sessions did not result in additional intervention effects. Conclusion: Extending cardiac rehabilitation with a face-to-face behavioral intervention resulted in additional long-term improvements in fatigue and small improvements in functional capacity up to 12 months. A telephonic behavioral intervention provided no additional benefits.

Objective: To determine the impact of an exercise-based prehabilitation (EBPrehab) program on pre- and postoperative exercise capacity, functional capacity (FC) and quality of life (QoL) in patients awaiting elective coronary artery bypass graft surgery (CABG). Design: A two-group randomized controlled trail. Setting: Ambulatory prehabilitation. Subjects: Overall 230 preoperative elective CABG-surgery patients were randomly assigned to an intervention (IG, n = 88; n = 27 withdrew after randomization) or control group (CG, n = 115). Intervention: IG: two-week EBPrehab including supervised aerobic exercise. CG: usual care. Main measures: At baseline (T1), one day before surgery (T2), at the beginning (T3) and at the end of cardiac rehabilitation (T4) the following measurements were performed: cardiopulmonary exercise test, six-minute walk test (6MWT), Timed-Up-and-Go Test (TUG) and QoL (MacNew questionnaire). Results: A total of 171 patients (IG, n = 81; CG, n = 90) completed the study. During EBPrehab no complications occurred. Preoperatively FC (6MWTIG: 443.0 ± 80.1 m to 493.5 ± 75.5 m, P = 0.003; TUGIG: 6.9 ± 2.0 s to 6.1 ± 1.8 s, P = 0.018) and QoL (IG: 5.1 ± 0.9 to 5.4 ± 0.9, P < 0.001) improved signiﬁcantly more in IG compared to CG. Similar effects were observed postoperatively in FC (6MWDIG: Δ-64.7 m, pT1–T3 = 0.013; Δ+47.2 m, pT1–T4 < 0.001; TUGIG: Δ+1.4 s, pT1–T3 = 0.003). Conclusions: A short-term EBPrehab is effective to improve perioperative FC and preoperative QoL in patients with stable coronary artery disease awaiting CABG-surgery.
