Guideline-based early rehabilitation after myocardial infarction. A pragmatic randomised controlled trial

OBJECTIVES: To determine the effectiveness of individualised educational behavioural treatment delivered by cardiac nurses in hospital compared to usual care for patients following acute myocardial infarction. METHODS: One hundred and fourteen consecutive patients were randomised to receive the intervention or usual care. Outcome assessment was by self-report questionnaire (the Hospital Anxiety and Depression Scale and Dartmouth COOP Health Status), interview at 1 month, and self-report at 3 and 12 months. The primary outcome was improvement in the Dartmouth COOP total score from baseline to 3 months. RESULTS: Four patients needed to be treated to give an additional patient with improvement in health status at 3 months (number needed to treat NNT] 4, 95% confidence intervals CIs] 3 to 12). The intervention group were more confident about returning to activities 1 month after discharge from hospital. Treated patients had fewer further treatment needs. CONCLUSIONS: An individualised educational behavioural treatment delivered by cardiac nurses in hospital may have substantial benefits. A large-scale pragmatic RCT is needed.
