Preliminary cost-outcome data presented at the Chicago 2008 American College of Cardiology meeting reported that; when including coronary CT calcium scores in the protocol to screen 495 asymptomatic firefighters, researchers were able to effectively triage subjects into follow-up coronary CTA or send them back to work without further workup, thus, decreasing cost. In another report presented, researchers concluded that cost was decreased in an out-patient cardiology clinic by incorporating coronary CTA in the risk-stratification of cardiac patients leading to reduced need for myocardial perfusion imaging and exercise treadmill testing over a 6-month period. Moreover, doctors were able to identify more coronary artery disease and provide more aggressive lipid management.
