How do exercise and stress management strategies compare to medical care alone in their effectiveness at reducing emotional distress and cardiovascular risk markers?
What will be an ideal response?
Blumenthal et al. demonstrated that exercise and stress management were more effective at reducing emotional distress and cardiovascular risk markers than medical care alone in their randomized controlled trial study. However, one review of 36 trials concluded that stress management alone showed no strong evidence for reducing cardiac mortality even though it was associated with a reduction of non-fatal MIs. The authors also expressed concern about the poor quality of many of the studies examined and saw a tendency toward publication bias of favorable studies. As a result, they expressed skepticism about the validity of some of the results that showed beneficial outcomes for stress management. Evidence for the use of exercise-based rehabilitation programs for CHD is more supportive and on average these programs result in a 31% reduction in cardiac-related mortality for those with CHD.
