BACKGROUND: The Screening for Heart Attack Prevention and Education (SHAPE) Task Force recommends noninvasive atherosclerosis imaging of all asymptomatic men (aged 45-75 years) and women (aged 55-75 years), except those at very low risk, to augment conventional cardiovascular risk assessment algorithms. METHODS: Among 2611 participants in the Dallas Heart Study aged 30 to 65 years who underwent computed tomography to measure coronary artery calcification, low-density lipoprotein cholesterol (LDL-C) therapeutic targets were calculated using both National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) and SHAPE algorithms. The proportion of subjects reclassified as being "at goal" for LDL-C vs "not at goal" after implementation of the SHAPE recommendations was determined. RESULTS: More subjects were identified with LDL-C levels greater than or equal to goal based on SHAPE than on NCEP-ATP III (27.4% vs 21.6%), with 7.0% of individuals reclassified as having unmet LDL-C goals and 1.1% of individuals reclassified as at goal. When more aggressive optional LDL-C goals were implemented, 31.7% had LDL-C levels greater than or equal to goal using SHAPE recommendations vs 28.1% using NCEP-ATP III recommendations, with 6.3% of subjects reclassified as being not at goal and 2.7% as being at goal. CONCLUSIONS: The SHAPE recommendations resulted in bidirectional reclassification of eligibility for lipid-lowering therapy in subjects aged 30 to 65 years. While broad implementation of these recommendations would modestly increase cholesterol-lowering drug use in this age range, the magnitude of the increase depends on whether standard or optional LDL-C goals are targeted.
