There is limited evidence to suggest that CVD systematic risk assessment may have some favourable effects on cardiovascular risk factors .
BACKGROUND Screening programmes can potentially identify people at high cardiovascular risk and reduce cardiovascular disease ( CVD ) morbidity and mortality .
However , there is currently not enough evidence showing clear clinical or economic benefits of systematic screening-like programmes over the widely practised opportunistic risk assessment of CVD in primary care setting s.

Multifactorial trial in the prevention of coronary heart disease: 3. Incidence and mortality results.
Incidence and mortality results are presented from an international controlled trial of multifactorial prevention of coronary heart disease , involving r and omization of 66 factories ( 49 781 men ) in U.K. , Belgium , Italy and Pol and ( Cracow ) . Results for Pol and ( Warsaw ) are not yet complete . Net average reductions in risk factors ( all subjects ) were 1.2 % for plasma cholesterol , 8.9 % for daily cigarettes , 0.4 % for weight , 2.0 % for systolic blood pressure , and 11.1 % for a combined risk estimate . Greater reductions occurred in high-risk subjects ( 19.4 % for the combined estimate ) . The net overall reduction in CHD rates was 7.4 % ( 95 % confidence interval -29 to + 15 % ) for deaths ( 722 cases ) , and 3.9 % ( 95 % confidence interval -10 to + 2 % ) for fatal CHD + non-fatal myocardial infa rct ion ( 1502 cases ) . Among men aged 40 - 49 the reduction for this end-point was 15 % ; at ages 50 - 59 there was a small net increase . All-causes deaths after an early adverse trend showed 2.7 % reduction overall . There were large differences between centres , ranging from a 5 % net increase in CHD for U.K. to a decrease of 24 % in Belgium . In Belgium the decrease both in CHD and in all deaths was significant at the 5 % level . The effect on CHD in the different centres correlated broadly with their changes in risk factors . It is concluded that reduction in major coronary risk factors in industrial population s is possible , but it depends on adequate re sources ; the results support the hypotheses that CHD risk in middle-aged men is reversible and that community intervention can be beneficial
