SECONDARY outcome

Timeframe: 1 year

Population: all participants with follow up data

To evaluate if treatment with apixaban therapy, as compared to warfarin therapy, will modify the progression, regression and stabilization of coronary atherosclerosis. Modifications will include differences in plaque volume, composition and arterial remodeling; as well as new atherosclerosis formation. The scale is based upon volume of plaque in the coronary arteries, with zero being no plaque and a higher number being more plaque. There is no scale or maximum measure, this is a linear measure of atherosclerosis volume in the coronary arteries and more is worse. None is best, any plaque is considered worse, and a higher plaque volume represents more atherosclerosis. An individual of average health will have a score of 50.
