Prevalence and Impact of Musculoskeletal Comorbidities in Cardiac Rehabilitation
Bibliographic record
Abstract
In Brief BACKGROUND: With the demographic of patients entering cardiac rehabilitation (CR) indicating an older and more obese population, musculoskeletal comorbidities (MSKCS) may be escalating. METHODS: Musculoskeletal comorbidities affecting exercise were ascertained in 322 patients (233 men and 89 women) by a questionnaire and then an interview before and after 3 months of CR. Outcome variables were measured at baseline and 6 months. RESULTS: Musculoskeletal comorbidities perceived to affect exercise were reported by 50% of subjects at CR entry (48.1% of males, 55.1% of females; P = .26); most commonly occurring in the knee(s) (25%) and back (19%) due predominantly to arthritis (36.6%) and strains/sprains (28.6%). Multivariate regression revealed that greater body mass, older age, and lower peak oxygen uptake ( ) were predictors of baseline MSKCs. At entry, patients with MSKCs were less likely to be exercising 30 minutes or more, 5 times per week than those without MSKCs (17.4% vs 28%, respectively, P = .03). Exercise modifications were required for 33.5% of patients with MSKC. By 3 months, 15.2% of patients developed 62 new MSKCs (26.5% strains/sprains). Six months of CR yielded significant (P < .001) and similar improvements in for patients with and without baseline MSKCs (16.3% and 18.8%, respectively, P = .28). The improvement was mitigated in those with arthritic conditions compared with others (7.8% vs 20%, respectively, P = .01). By 6 months, 31.1% and 29.8% of patients with and without baseline MSKCs respectively, discontinued CR (P = .81). CONCLUSIONS: At entry to CR, patients reporting MSKCs had a poorer health profile than those without mskcs, including lower levels of physical activity and cardiovascular fitness, and unfavorable anthropometric measures. With exercise modifications, significant benefits were achievable without affecting compliance. Musculoskeletal comorbidities affecting exercise were reported by 50% of subjects at entry to cardiac rehabilitation. Multivariate regression revealed that greater body mass, older age, and lower peak oxygen uptake were associated with baseline musculoskeletal comorbidities. With exercise modifications, significant benefits in outcomes were achieved without affecting exercise compliance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
