To demonstrate the impact of cardiac CT (CTCA) in the stratification of cardiovascular risk in a population of asymptomatic patient with classic risk factors for coronary artery disease (CAD) compared to the systematic coronary risk evaluation (SCORE).

We included 123 asymptomatic patients (97 men/ 26 women; age 51.3 ±7.2) who underwent CTCA after clinical evaluation during which a risk for cardiovascular events in 10 years with the SCORE was calculated. Calcium score was also evaluated. Three possible outcomes were hypotized: patient with no CAD, patients with non-significant coronary stenosis, and patients with significant coronary stenosis. On the basis of CACA results, we developed a simulation model to evaluate the effect on patient management.

The pretest risk of cardiovascular events in the asymptomatic population was 1,06%. The average value of calcium score was 56.48 ± 176.61 (moderate risk). We found 17 patients with significant coronary stenosis who underwent coronary revascularization. Over 50 patients with non- significant coronary stenosis began a medical treatment with statins. The average risk for cardiovascular events was 0,42 ± 0,66 after a cardiac CT exam.

We demonstrated an hypothetical reduction of the average risk for cardiovascular events using cardiac CT.

Better stratification of cardiovascular risk using Cardiac-CT.
