Conclusions We found that psychological intervention  improved psychological symptoms and reduced cardiac mortality for people with CHD .
However , there remains considerable uncertainty regarding the magnitude of these effects and the specific techniques most likely to benefit people with different presentations of CHD
Background Although psychological interventions are recommended for the management of coronary heart disease ( CHD ) , there remains considerable uncertainty regarding their effectiveness .
Physical training and relaxation therapy in cardiac rehabilitation assessed through a composite criterion for training outcome.
One hundred fifty-six myocardial infa rct ion patients were r and omly assigned to either exercise plus relaxation and breathing therapy ( treatment A , n = 76 ) or to exercise training only ( treatment B , n = 80 ) . Effects on exercise testing showed a more pronounced training bradycardia and a remarkable improvement in ST abnormalities in treatment A ( p less than 0.005 ) . A model was developed to integrate the various exercise parameters into a single measure for training benefit . Approximately half the patients showed a training success , with a more positive and less negative outcome in treatment A ( p = 0.09 ) . The odds for failure were 0.25 for treatment A and 0.51 for treatment B ( odds ratio : 2.04 ; 95 % confidence interval , 0.94 to 4.6 ) . Thus the risk of failure was reduced by half when relaxation was added to exercise training . These results indicate that exercise training is not successful in all MI patients and that relaxation therapy enhances training benefit
