Triple-Parametric Optical Mapping for Simultaneous Measurement of Transmembrane Potential, Intracellular Calcium and NADH

Case ID: 022-005-Efimov

Researchers at GW have developed a novel triple-parametric optical mapping method that can effectively, accurately, and simultaneously measure metabolic, electrical, and contractile components associated with cardiac physiology. As a result, this allows effective clinical management of cardiac procedures especially with regards to one aspect known in the art as metabolism-excitation-contraction coupling (MECC). Further, the disclosed triple-parametric optical mapping method can effectively assist in the drug development process by means of effectively determining appropriate dosing for a subject while also accounting for toxicity considerations of the aforementioned dosing. The method also effectively allows analysis of repolarization-related parameters by effectively utilizing electromechanical uncouplers known in the art.

The disclosed invention can be implemented as either a system, a method, or a device as can be appreciated. The system or method can include various aspects including the following: (i) at least one optical system, for each of the metabolic, electrical, and contractile components associated with cardiac physiology, that can effectively, accurately, and simultaneously measure relevant parameters as can be appreciated; (ii) at least one optical source that can effectively, accurately, and simultaneously assist in measuring the parameters as can be appreciated. In one embodiment, the parameters include the following: transmembrane potential, intracellular calcium, and NADH.
