Detection of Subclinical Atherosclerosis in Asymptomatic Individuals
Completed
Conditions studied: Coronary Artery Disease
In brief
This study will evaluate the use of cardiac CT in identifying atherosclerosis plaque in patients who have not been diagnosed with atherosclerosis and who have no symptoms of the disease but who are at risk of developing atherosclerosis based on traditional risk factors such as diabetes or a family history of coronary artery disease.

- no prior coronary revascularization procedure
- Aymptomatic
- no chest pain, shortness of breath, angina or angina-equivalent that is assumed to be related to myocardial ischemia
- Presence of a high-risk feature (at least one of the following four will quality)
