About the Gensini Score
The Gensini Score is an angiographic scoring system used to quantify the extent and severity of coronary atherosclerotic disease. Each lesion is assigned a nonlinear stenosis severity score and multiplied by a location-dependent factor.
The conventional severity scores are: 1–25% = 1, 26–50% = 2, 51–75% = 4, 76–90% = 8, 91–99% = 16, and 100% = 32.
For an exact 99% subtotal lesion receiving collateral flow, the conventional collateral correction subtracts 8 points from the severity score. For a 100% occlusion receiving collateral flow, the correction depends on the degree of stenosis in the donor artery.
Segment weighting includes left main ×5, proximal LAD ×2.5, mid LAD ×1.5, distal LAD ×1, D1 ×1, D2 ×0.5, proximal LCx ×2.5 in right dominance and ×3.5 in left dominance, and conventional weighting for the remaining coronary segments.
Important: The Gensini Score is a quantitative angiographic burden score. There is no universally accepted set of "mild", "moderate", or "severe" cutoffs applicable to every clinical population.
