Despite these successes, however, there were additional questions. Would the reduction in risk be translated into a reduction in morbidity and mortality? The North Karelia Project was apparently associated with a fall in mortality as was the Belgium Heart Disease Prevention Program. However, the U.K. Heart Disease Prevention Project was not effective nor was the Multiple Risk Factor Intervention Trial in reducing mortality. It is an appropriate responsibility of the scientific community to inform the general public of the implications of this research and to give advice on the prudent preventive measures.
