Abstract

fetched live from OpenAlex

OBJECTIVE: To compare the long-term effectiveness of hospital versus telephone-monitored home-based exercise training during cardiac rehabilitation (CR) on exercise capacity and habitual physical activity. DESIGN: Six-year follow-up of patients who participated in a randomised controlled trial of hospital versus monitored home-based exercise training during CR after coronary artery bypass graft surgery. SETTING: Outpatient CR centre in Central-South Ontario, Canada. PARTICIPANTS: 196 Patients who participated in the original randomised controlled trial and who attended an evaluation 1 year after CR. INTERVENTIONS: 6 months of home or hospital-based exercise training during CR. MAIN OUTCOME MEASURES: Peak oxygen uptake (peak Vo₂), Physical Activity Scale in the Elderly (PASE) to assess habitual activity, semi-structured interviews to assess vital status, demographic and descriptive information. RESULTS: Of the 196 eligible patients, 144 (75.5%; 74 Hospital, 70 Home) were available for participation. Patients were predominantly male (n = 120; 83.3%) aged 70 ± 9.5 years. Clinical and sociodemographic outcomes were similar in both groups. While exercise performance declined over time, there were significant between-group differences in peak Vo₂) (1506 ± 418 ml/min vs 1393 ± 341 ml/min; p = 0.017) and PASE scores (166.7 ± 90.2 vs 139.7 ± 66.5; p = 0.001) at 6-year follow-up in favour of the home group. CONCLUSIONS: Home and hospital-based exercise training maintained exercise capacity above pre-CR levels 6 years after CR. Exercise training initiated in the home environment in low-risk patients undergoing coronary artery bypass graft surgery conferred greater long-term benefit on Vo₂ and persistent physical activity compared with traditional hospital-based CR.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
