ABSTRACT:
A method and apparatus for evaluating the viability of a tissue of interest, particularly that presents as dead but may be merely stunned or hibernating with reduced or no contractility. Dynamic measurement of oxidative metabolism permits distinguishing between different stages of compromised myocardium. Measurements can be made using near-infrared illumination and detection coupled with infusion of one or more metabolic substrates to the region of interest to evaluate whether a metabolic pathway cascade or a trans-membrane ionic potential are intact and thereby provide an indication of the viability of the cell.
