Comprehensive Cardiac Rehabilitation for Secondary Prevention After Transient Ischemic Attack or Mild Stroke
Bibliographic record
Abstract
BACKGROUND AND PURPOSE: Comprehensive cardiac rehabilitation (CCR), which integrates structured lifestyle interventions and medications, reduces morbidity and mortality among cardiac patients. CCR has not typically been used with cerebrovascular populations, despite important commonalities with heart patients. We tested feasibility and effectiveness of 6-month outpatient CCR for secondary prevention after transient ischemic attack or mild, nondisabling stroke. This article presents risk factors. A future article will discuss psychological outcomes. METHODS: Consecutive consenting subjects having sustained a transient ischemic attack or mild, nondisabling stroke within the previous 12 months (mean, 11.5 weeks; event-to-CCR entry) with ≥1 vascular risk factor, were recruited from a stroke prevention clinic providing usual care. We measured 6-month CCR outcomes following a prospective cohort design. RESULTS: Of 110 subjects recruited from January 2005 to April 2006, 100 subjects (mean age, 64.9 years; 46 women) entered and 80 subjects completed CCR. We obtained favorable, significant intake-to-exit changes in: aerobic capacity (+31.4%; P<0.001), total cholesterol (-0.30 mmol/L; P=0.008), total cholesterol/high-density lipoprotein (-11.6%; P<0.001), triglycerides (-0.27 mmol/L; P=0.003), waist circumference (-2.44 cm; P<0.001), body mass index (-0.53 kg/m(2); P=0.003), and body weight (-1.43 kg; P=0.001). Low-density lipoprotein (-0.24 mmol/L), high-density lipoprotein (+0.06 mmol/L), systolic (-3.21 mm Hg) and diastolic (-2.34 mm Hg) blood pressure changed favorably, but nonsignificantly. A significant shift toward nonsmoking occurred (P=0.008). Compared with intake, 11 more individuals (25.6% increase) finished CCR in the lowest-mortality risk category of the Duke Treadmill Score (P<0.001). CONCLUSIONS: CCR is feasible and effective for secondary prevention after transient ischemic attack or mild, nondisabling stroke, offering a promising model for vascular protection across chronic disease entities. We know of no similar previous investigation, and are now conducting a randomized trial.

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.
