ASCOD grade breakdown
| C1 | Significant cardiac pathology and single infarct | Left ventricle EF <35% | ||
| 7.4% (13) | 2.3% (4) | |||
| C2 | Left ventricle apical akinesia and decreased EF | No cardiac pathology but multiple infarcts | ||
| 4.0% (7) | 10.3% (18) | |||
| O1 | Moyamoya disease | Systemic lupus | ||
| 2.9% (5) | 2.3% (4) | |||
| O3 | Abnormal hypercoagulability laboratories (see Methods) | Homocysteinemia <40 μmol/L | Antiphospholipid AB <100 GPL units | Thrombocytosis <800 000/mm3 |
| 12.6% (22) | 8.6% (15) | 5.7% (10) | 2.9% (5) |
Within each ASCOD grade, specific pathologies were quantified.
EF, ejection fraction.
