Insights
Lifestyle modification programs for coronary heart disease patients significantly reduce mortality and cardiac events. These programs improve risk factors and health behaviors, offering benefits beyond standard clinical care.
Area of Science:
- Cardiology
- Preventive Medicine
- Health Behavior Science
Background:
- Lifestyle modification programs (LMPs) are established interventions for coronary heart disease (CHD) patients, improving risk factors, quality of life, and mortality.
- Recent advancements in routine cardiac care may impact the added benefits of older LMP designs.
Purpose of the Study:
- To systematically review and meta-analyze the efficacy of LMPs for CHD patients developed between 1999 and 2009.
- To assess the impact of LMPs on mortality, cardiac events, risk factors, and health behaviors.
Main Methods:
- Systematic review and meta-analysis of 23 randomized controlled trials.
- Inclusion of 11,085 randomized patients diagnosed with coronary heart disease.
Main Results:
- LMPs were associated with significant reductions in all-cause mortality (OR 1.34) and cardiac mortality (OR 1.48).
- Cardiac readmissions and non-fatal reinfarctions were reduced (OR 1.35) with LMPs.
- Positive effects on risk factors and behaviors were observed at post-treatment (10.2 months) and long-term follow-up (33.7 months).
- Programs incorporating goal setting, self-monitoring, planning, and feedback showed greater improvements in diet and exercise.
Conclusions:
- LMPs provide significant benefits for coronary heart disease patients, complementing routine clinical care.
- The findings support the continued implementation and refinement of LMPs in cardiac rehabilitation.
- Self-regulation techniques enhance the effectiveness of lifestyle modification interventions for CHD.
Background:
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.
