WebHigh aspirin platelet reactivity (≥550 aspirin reaction units), with or without high clopidogrel platelet reactivity (>208 P2Y 12 reaction units), was not associated with clinical outcomes. 22 High clopidogrel reactivity (>208 P2Y 12 reaction units), however, was an independent predictor of 1-year stent thrombosis and MI (HR 2.49, 95% CI, 1. ... WebJan 1, 2010 · Reactivity is the measure of the departure of a reactor from critical. The effective multiplication factor, k eff, determines whether the neutron density within a reactor will remain constant or change.Since the power level is directly proportional to the neutron density, whenever k eff = 1.0, the reactor is critical and operates at a constant power level.
