Available studies show convincingly the health benefits of lifestyle changes in CAD patients .
Effect estimates of combined dietary changes look promising .
BACKGROUND Guidelines for lifestyle and dietary modification in patients with coronary artery disease ( CAD ) are mainly supported by evidence from general population studies .
CAD patients , however , differ from the general population in age ( older ) and treatment with preventive drugs .
This review seeks to provide evidence for a prognostic benefit of lifestyle and dietary recommendations from studies in CAD patients .
Lack of benefit of dietary advice to men with angina: results of a controlled trial
Objective : To see whether mortality among men with angina can be reduced by dietary advice . Design : A r and omized controlled factorial trial . Setting : Male patients of general practitioners in south Wales . Subjects : A total of 3114 men under 70 y of age with angina . Interventions : Subjects were r and omly allocated to four groups : ( 1 ) advised to eat two portions of oily fish each week , or to take three fish oil capsules daily ; ( 2 ) advised to eat more fruit , vegetables and oats ; ( 3 ) given both the above types of advice ; and ( 4 ) given no specific dietary advice .  Mortality was ascertained after 3–9 y. Results : Compliance was better with the fish advice than with the fruit advice . All-cause mortality was not reduced by either form of advice , and no other effects were attributable to fruit advice . Risk of cardiac death was higher among subjects advised to take oily fish than among those not so advised ; the adjusted hazard ratio was 1.26 ( 95 % confidence interval 1.00 , 1.58 ; P=0.047 ) , and even greater for sudden cardiac death ( 1.54 ; 95 % CI 1.06 , 2.23 ; P=0.025 ) . The excess risk was largely located among the subgroup given fish oil capsules . There was no evidence that it was due to interactions with medication . Conclusion : Advice to eat more fruit was poorly complied with and had no detectable effect on mortality . Men advised to eat oily fish , and particularly those supplied with fish oil capsules , had a higher risk of cardiac death . This result is unexplained ; it may arise from risk compensation or some other effect on patients ' or doctors ' behaviour .
