Myocardial blush grade - grading of myocardial perfusion during coronary angiography
Myocardial blush grade evaluates contrast density in the myocardial region of the infarct-related artery compared to regions of noninfarct-related arteries on coronary angiography.
| Myocardial blush grade - MBG | Description |
|---|---|
| MBG 0 | no myocardial blush (or contrast density) or persisting blush (staining) |
| MGB 1 | minimal myocardial blush (or contrast density) |
| MBG 2 | moderate myocardial blush (or contrast density) but less than that obtained during angiography of a contralateral of ipsilateral noninfarct-related coronary artery |
| MBG 3 | normal myocardial blush (or contrast density) |
