[Tolerance to physical exertion after myocardial infarct as a method of evaluation of coronary circulation and cardiac function].
Twenty healthy individuals and 61 persons who had suffered from myocardial infarction 3 to 18 months previously were examined. They were all males under the age of 50. Tolerance of healthy persons to physical load on a treadmill (according to a standard program) was 3.6 steps of the treadmill test with maximum pulse rate of 166 +/- 2 per minute. The tolerance to load of persons who had a history of myocardial infarction was much lower and varied mainly with the severity of coronary insufficiency. An inadequate reaction of the cardiovascular system to the load was revealed in most of them.
