[Value of linsidomine (SIN 1) in the evaluation of myocardial viability by 201-Tl scintigraphy after exertion].
201Tl scintigraphy can be used to determine exercise-induced ischemia and the viability of the hypoperfused myocardium as a function of radiotracer redistribution. Redistribution is calculated by differential analysis of the normalized circumferential curves of activity. Intravenous injection of linsidomine (SIN 1) a patent coronary vasodilatator, gives more reliable results than conventional imaging at the 4th h, and compares favourably with the results obtained at the 24th h after reinjection of 201 Tl. Linsidomine provides images in 60 to 90 min, in stable clinical conditions.
