Comparisons of thrombotic angiographic characteristics between lesions in Group 2 and Not-Group 2.
| Characteristics | Group 2 (n = 73) (highly probable coronary thrombus) vs. Not-Group 2 (n = 250)

|||||
|---|---|---|---|---|---|---|
| Group 2 N (%) | Not-Group 2 N (%) | GEE OR (95% CI) | P | Sensitivity % (95% CI) | Specificity % (95% CI) | |
| Complex Ambrose morphology | 5 (6.9) | 14 (5.6) | 1.07 (0.9, 1.31) | 0.5 | 14 (8, 23) | 94 (89, 96) |
| Presence of spherical, ovoid or irregular filling defect | 10 (13.7) | 1 (0.4) | 60.8 (3.84, 961) | 0.004 | 22 (13, 35) | 100 (96, 100) |
| Presence of abrupt vessel cutoff with persistence of contrast | 20 (27.4) | 18 (7.2) | 2.72 (1.12, 6.57) | 0.03 | 32 (22, 45) | 94 (89, 96) |
| Presence of intraluminal staining | 9 (12.3) | 3 (1.2) | 8.18 (2.12, 31.6) | 0.002 | 17 (9, 29) | 99 (97, 100) |
| Presence of any coronary filling defect* | 14 (19.2) | 5 (2.0) | 8.53 (2.7, 26.9) | 0.0003 | 26 (16, 39) | 98 (95, 99) |
GEE OR — generalized estimating equations-estimated odds ratio between groups; CI — confidence interval
Group 2 — individual lesions with highly probable coronary thrombus [ST elevation in territory of >70% stenosis and elevated troponin]
*
Any coronary filling defect includes spherical, ovoid, irregular, hazy, occlusive filling defects and obstructive coronary dissections
