5 Biomarkers Included
- Max Stenosis CircumflexA measurement of the worst point of narrowing along the left circumflex artery, one of the main blood vessels that feeds your heart muscle.
- Max Stenosis LADA measurement of the most narrowed point inside the heart's largest and most important artery, the one that supplies blood to the front wall of the heart.
- Max Stenosis LMThe percentage of narrowing at the worst point along the main artery that supplies most of the heart with blood.
- Max Stenosis RCAA measurement from a heart scan that shows how narrowed the worst-affected spot in the artery supplying the bottom and back of your heart has become from plaque buildup.
- Max Stenosis Ramus IntermediusA measurement of the worst narrowing inside a coronary artery branch called the ramus intermedius, captured on heart imaging to show how much plaque is blocking blood flow.
