Predictive Value of Coronary Artery Calcium Score From Nongated Chest CT Scans Compared With Gated Scans and Incidence of Cardiovascular Events
Authors' conclusion
Nongated CAC predicts cardiovascular events with performance comparable to gated CAC.
Study context
- Population
- MESA exam 5 participants without previous CHD or CVD who underwent same-day gated and nongated chest CT, April 2010 to December 2011of 2601 scanned
- Participants
- 2,472 participants
- Exposure
- Nongated coronary artery calcium (CAC) vs gated CAC for prediction of CHD/CVD events
- Outcome
- Incident CHD/CVD events
Methodological detailspaired same-day gated and nongated CT, core laboratory, blinded to acquisition methodology
