Multifactorial lifestyle interventions aim ed at improving modifiable risk factors in patients with established CHD reduce the risk for fatal cardiovascular events .
Therefore , they may have added value in secondary prevention of CHD
CONTEXT Coronary heart disease ( CHD ) is responsible for about 15 % of all deaths worldwide and is identified as a top priority for decision makers .
Both primary and secondary prevention are considered key strategies in the prevention of CHD .
The aim of this study was to assess the efficacy of nonpharmacologic interventions with multiple lifestyle components in patients with established CHD in comparison to usual care .
Attenuated progression of coronary artery disease after 6 years of multifactorial risk intervention: role of physical exercise.
BACKGROUND It was the aim of this study to assess the long-term effects of physical exercise and low-fat diet on the progression of coronary artery disease . At the beginning of the study , 113 male patients with coronary artery disease were r and omized to an intervention group ( n=56 ) or a control group ( n=57 ) ; 90 patients ( 80 % ) could be reevaluated after 6 years . METHODS AND RESULTS Patients in the intervention group ( n=40 ) showed a reduction in total serum cholesterol ( 6.03+/-1.03 versus 5.67+/-1.01 mmol/L ; P<.03 ) and triglyceride levels ( 1.94+/-0.8 versus 1.6+/-0.89 mmol/L ; P<.005 ) and maintained their initial body mass index ( 26+/-2 versus 27+/-2 kg/m2 ; P = NS ) , but results were not statistically different from the control group ( n=50 ) ( total serum cholesterol , 6.05+/-1.02 versus 5.79+/-0.88 mmol/L ; triglycerides , 2.25+/-1.28 versus 1.85+/-0.96 mmol/L [ both P = NS ] ; body mass index , 26+/-2 versus 28+/-3 kg/m2 [ P<.0001 ] ) . In the intervention group , there was a significant 28 % increase in physical work capacity ( 166+/-59 versus 212+/-89 W ; P<.001 ) , whereas values remained essentially unchanged in the control group ( 165+/-51 versus 170+/-60 W ; P = NS ; between groups , P<.05 ) . In the intervention group , coronary stenoses progressed at a significantly slower rate than in the control group ( P<.0001 ) . Energy expenditure during exercise was assessed in a subgroup ; patients with regression of coronary stenoses spent an average of 1784+/-384 kcal/wk ( approximately 4 hours of moderate aerobic exercise per week ) . Multivariate regression analysis identified only physical work capacity as independently contributing to angiographic changes . CONCLUSIONS After 6 years of multifactorial risk intervention , there is significant and persistent improvement in lipoprotein levels and physical work capacity , which results in a significant retardation of disease progression . These beneficial effects appear to be largely due to chronic physical exercise
