Lifestyle modification programmes for coronary heart disease patients
have been shown to effectively improve risk factors and related health
behaviours, quality of life, reincidence, and mortality. However, improvements in
routine cardiac care over the recent years may offset the incremental benefit
associated with older programmes. PURPOSE: To determine the efficacy of lifestyle
modification programmes for coronary heart disease patients developed over the
last decade (1999-2009) by means of a systematic review and meta-analysis.
RESULTS: The study included 23 trials (involving 11,085 randomized patients).
Lifestyle modification programmes were associated with reduced all-cause
mortality (summary OR 1.34, 95% CI 1.10-1.64), cardiac mortality (summary OR
1.48, 95% CI 1.17-1.88), and cardiac readmissions and non-fatal reinfarctions
(summary OR 1.35, 95% CI 1.17-1.55). Furthermore, lifestyle modification
programmes positively affected risk factors and related lifestyle behaviours at
posttreatment (M = 10.2 months), and some of these benefits were maintained at
long-term follow up (M = 33.7 months). Improvements in dietary and exercise
behaviour were greater for programmes incorporating all four self-regulation
techniques (i.e. goal setting, self-monitoring, planning, and feedback
techniques) compared to interventions that included none of these techniques.
CONCLUSION: The evidence summarized in this meta-analysis confirms the benefits
of lifestyle modification programmes - over and above benefits achieved by
routine clinical care alone.
