Current Guidelines
| Guideline | Recommendation | ||
|---|---|---|---|
| Class | Level of Evidence | ||
| 2013 ACC/AHA Guideline on the Assessment of Cardiovascular Risk | If after quantitative risk assessment, a risk-based decision is uncertain, one or more of the following tools may be used to aid in decision making: family history, hs-CRP, CAC score or ABI. | IIb | B |
| 2016 European Guidelines on Cardiovascular Disease Prevention In Clinical Practice | CAC may be considered as a risk factor in CV risk assessment in patients with a calculated SCORE risk between 5% to 10%. | IIb | B |

| ACCF/SCCT/ACR/AHA/ASE/ASNC/NASCI/SCAI/SCMR
2010 Appropriate Use Criteria for Cardiac Computed Tomography |
CAC would be appropriate in patients with a 10-20% 10-year risk of CHD. | Appropriate | |
| CAC would be appropriate in low risk patients (<10% 10-year risk of CHD) with a family history of premature CHD. | Appropriate | ||
| The usefulness of CAC is uncertain in patients with peripheral arterial disease or other coronary risk equivalents, or have a 10-year CHD risk greater than 20%, or who are 40 or older with diabetes. | Uncertain | ||
| CAC would be inappropriate in low risk patients (<10% 10-year risk of CHD). | Inappropriate | ||
