All the patients had preliminary instrumental studies, including exercise test, echocardiography, hyperventilation and orthostatic tests, and variation pulsometry. A regression equation was derived, which could predict the efficacy of foridon from the findings of the tests used. The antianginal effect of foridon was found to be the weakest among the other drugs under study.
