[Dynamic observations of tolerance to physical exercise in patients with ischemic heart disease during drug therapy].

Proceeding from a dynamic observation of the tolerance of physical exercises in the process of drug therapy of 90 patients with ischaemic heart disease the author concludes that a certain dissociation exists between the subjective effect of the antianginal drugs and the results of bicycle tests in the evaluation of the efficacy of the treatment. While a subjective improvement was declared in 2/3 of the patients, the exercise test indices improved only in 1/3. The bicylce test before and after the therapeutic course seems to facilitate a more precise evaluation of the efficacy of the antianginal drugs.
