Question normal

In the vast majority of the relevant articles Gensini score has been calculated taking into consideration 2 factors for each lesion [1. severity score & 2. region multiplying factor]. However, in its first description [Gensini GG. Coronary arteriography. In: Heart Disease. Braunwald E, ed. Philadelphia: WB Saunders, 1980:352-353] is taken into account an additional third parameter, the modifying influence of the collaterals with the severity score adjustment factor.
