Table 3.
Reclassification of risk (30 day probability of cardiovascular death and myocardial infarction) for those who did and did not experience primary outcome in model that included findings on coronary computed tomographic angiography (CCTA) compared with model that included only revised cardiac risk index (RCRI) scores*
RCRI scores only | Model that included CCTA findings | ||||||
---|---|---|---|---|---|---|---|
Patients who had an event | Patients who did not have an event | ||||||
<5% | 5%-15% | >15% | <5% | 5%-15% | >15% | ||
<5% | 5 | 10 | 0 | 191 | 114 | 0 | |
5%-15% | 0 | 41 | 7 | 47 | 453 | 37 | |
>15% | 0 | 1 | 10 | 0 | 10 | 29 |
*CCTA risk reclassification for those who experienced primary outcome was: (17−1)/74=22%, 95% confidence interval 10% to 33%; P<0.001. Risk reclassification for those who did not experience primary outcome was: (57−151)/881=−11%, −14% to −7%; P<0.001.
