The aim of the research was to assess the value of the bicycle exercise test in patients after acute myocardial infarction (MI) as an indicator of prognosis and evaluation of efficiency of the recovery treatment. The study involved 193 patients observed one year after MI and a group of 27 postinfarction persons after coronary artery bypass surgery (CABG) in which the remaining exercise tolerance did not exceed 50 W. The relationship
between the exercise load and number and severity of coronary stenoses was established. During the first year after MI in 42% patients we noted increase of exercise tolerance, in 37% patients it remained unchanged, and
in 21% it decreased. Increase of exercise tolerance occurred mainly in patients with initially low (25–50 W) threshold load. Determining the level of exercise tolerance is of especially great importance as a diagnostic
factor before revascularization, while as prognostic efficiency of revascularization does not always depend on the surgical treatment performed.
