Coronary CT angiography
- Gated CT of heart timed during peak contrast enhancement in coronary arteries
- NTG given to dilate coronary arteries. β-blockers commonly used to lower HR.
- CT-FFR: uses computational fluid dynamics to estimate fxnal significance of focal lesions
- CAD-RADS score in stable CP improves risk stratif. of CV events (JACC Img 2020;13:1534)
- In stable outPt w/ CP: CCTA added to stnd of care → ↑ early but not overall angiography/revasc; ↑ use of preventive med Rx, and ↓ coronary death/MI by 5 y (NEJM 2018;379:924)
