A method of determining the viability of a hibernating or stunned myocardial segment comprises the administration of ribose, a vasodilator and an inotropic agent. The preferred agent is dobutamine, which has both a vasodilation and an inotropic effect. The segments may be identified by myocardial imaging by any known means, such as echocardiography, Thallium-201 tracing or positron emission tomography. Ribose is preferably given one minute to three hours prior to administration of the vasodilator and inotropic agents.

Method for determining viability of a myocardial segment

The administration of ribose raises the hypoxic threshold of mammals experiencing a hypoxic condition. The presence of an effective amount of ribose in the tissue of a mammal increases the tolerance to hypoxia and decreases the symptoms of hypoxia in mammals experiencing chronic hypoxia due to cardiovascular disease or peripheral vascular disease. Such mammals are additionally benefited by administration of ribose and a vasodilator or an isotropic agent. Mammals experiencing transient hypoxia from high altitude, anesthesia or exercise are also benefited.
