Does the addition of resistance and balance training to usual cardiac rehabilitation improve functional capacity in very old adults after coronary bypass surgery?
Adding intensive resistance and balance training to standard inpatient cardiac rehabilitation significantly improves functional capacity in very old patients recovering from coronary bypass surgery.
Absolute Event Rate: 67.3% vs 41.9%
p-value: p=.003
OBJECTIVES: To compare the efficacy of intensive functional exercise training with that of usual cardiac rehabilitation (CR) in very old adults soon after coronary bypass surgery (CABG). DESIGN: Randomized controlled trial. SETTING: In-hospital CR. PARTICIPANTS: Individuals aged 75 and older (n = 173, mean 78.5 ± 3.2) participated in inpatient CR, which started soon after surgery (13.1 ± 5.3 days) and lasted for a mean of 20.4 ± 3.2 days. INTERVENTION: Participants were randomly assigned to an inpatient CR intervention group (IG; n = 84) or a control group (CG; n = 89). All participants participated in the inpatient CR program. In addition, IG participants participated in resistance training and special balance training (5 d/wk). MEASUREMENTS: Six-minute walk test, cardiopulmonary exercise testing, Timed-Up-and-Go Test (TUG), and a maximal isometric strength test were used to access functional capacity and the MacNew questionnaire to evaluate health-related quality of life (HRQL). RESULTS: There were significant improvements (P < .001) in all measured variables over the duration of CR. Improvements in functional capacity were significantly greater in the IG than the CG for 6-minute walk distance (6-MWD) (IG Δ 67.3 ± 49.0 m vs CG Δ 41.9 ± 51.7 m; P = .003), TUG time (IG Δ -2.4 ± 2.2 seconds vs CG Δ -1.2 ± 3.4 seconds; P = .005), and relative workload (IG Δ 0.19 ± 0.21 W/kg vs CG Δ 0.13 ± 0.11 W/kg; P = .03). CONCLUSION: There were significant improvements in all measured variables in very old adults participating in CR soon after CABG. With additional functional exercise training, participants randomized to IG improved significantly more than those randomized to CG on 6-MWD, TUG time, and relative workload.
Busch et al. (2012) conducted an RCT in Coronary bypass surgery (CABG) (n=173). Resistance and balance training vs. Usual cardiac rehabilitation was evaluated on Change in 6-minute walk distance (6-MWD) (p=.003). Adding resistance and balance training to usual cardiac rehabilitation in very old adults after CABG significantly improved 6-minute walk distance (Δ 67.3 m vs Δ 41.9 m; P=0.003).
