Multivariable associations of CAD assessing tools with MACE.
| Univariable analyses | Multivariable analyses | |||
|---|---|---|---|---|
| CAD assessment tool | HR (95% CI) | P-value | HR (95% CI) | P-value |
| Significant stenosis in ICA, (%) | 1.16 (0.41–3.26) | 0.780 | 0.70 (0.22–2.28) | 0.557 |
| Significant stenosis in CCTA, (%) | 1.10 (0.38–3.221) | 0.857 | 0.96 (0.30–3.10) | 0.942 |
| CACS, AU | 1.00 (1.00–1.00) | 0.318 | 1.00 (1.00–1.01) | 0.200 |
| RCA PCAT attenuation, HU | 1.09 (1.01–1.18) | 0.022 | 1.11 (1.02–1.20) | 0.015 |
The model was constructed via Cox proportional hazard regression; conventional CAD evaluating tools as well as the novel RCA PCAT attenuation were incorporated. n = 62. HR, hazard ratio; CI, confidence interval; AU, Agatston units; HU, Hounsfield units; ICA, invasive coronary angiography; CCTA, coronary CT angiography; CACS, coronary artery calcium score.
