Screening and improved selection of individuals for more effective prevention is now possible because of the following: 1) subclinical atherosclerosis develops slowly over several decades before it becomes clinically manifest; 2) screening methods are now available for detecting the presence and severity of subclinical atherosclerotic plaques; and 3) current primary prevention with aggressive risk factor modification can reduce morbidity and mortality from heart attacks and strokes by 50%.
