Cardiac Outcomes According to the Severity of CAD on CCTA During Median Follow‐up of 8.2 Years (IQR: 7.7–10.1 Years)
| Total (n=470) | Normal (n=170) | Nonobstructive CAD (n=224) | Obstructive CAD (n=76) | P Value | |
|---|---|---|---|---|---|
| Death | 104 (22.1) | 26 (15.3) | 52 (23.2) | 26 (34.2) | 0.004 |
| Cardiac | 16 (3.4) | 3 (1.8) | 5 (2.2) | 8 (10.5) | 0.001 |
| Noncardiac | 88 (18.7) | 23 (13.5) | 47 (21.0) | 18 (23.7) | 0.082 |
| Nonfatal MI | 8 (1.7) | 0 (0.0) | 4 (1.8) | 4 (5.3) | 0.011 |
| MACE (cardiac death or nonfatal MI) | 24 (5.1) | 3 (1.8) | 9 (4.0) | 12 (15.8) | <0.001 |
Values are number (percentage). CAD indicates coronary artery disease; CCTA, coronary computed tomography angiography; IQR, interquartile range; MACE, major adverse cardiac event; MI, myocardial infarction.
