[Tolerance and hemodynamic support for physical loading in patients in the early period of an acute large-focus myocardial infarct].

Tolerance to physical stress and hemodynamic support of the latter were compared in normal subjects, patients with chronic coronary disease and those at early stages after large-focal myocardial infarction. Tolerance to stress and its hemodynamic support were shown to be virtually identical in patients at early postinfarction stages and chronic coronary patients. It was therefore suggested that controlled bicycle ergometry was a safe test for patients at early stages after large-focal myocardial infarction (6 days, on average), and a useful one for the objective assessment of individual tolerance of varying load regimens.
