Cardio vascular risk stratification based on absolute coronary artery calcium score classes n (%)

CACS class	gCCT	ngCCT
0	6 (10)	10 (16.7)
1-10	6 (10)	7 (11.7)
11-100	14 (23.3)	10 (16.7)
101-400	14 (23.3)	17 (28.3)
400-1000	14 (23.3)	10 (16.7)
> 1000	6 (10)	6 (10)

The Table shows how the total Agatston score distributed using the Mayo Clinic Classification (Rumberger et al[17]) with gCCT and ngCCT within the same population. In total 23 (38.3%) patients shifted to a different cardiovascular risk group. gCCT: ECG gated cardiac computed tomography; ngCCT: Non-gated chest computed tomography.
