title: [Physical exertion tests in patients with acute myocardial infarct at the hospital stage of rehabilitation].
abstract: The aim of the work is to clarify the part of physical exertion tests applied to patients early after myocardial infarction, i.e. on the 30--35th day of the affection and also to appraise the reserves of the coronary circulation with a definite threshold tolerance to physical efforts. Tests with a graded physical loading were set up in 50 patients with acute macrofocal (including 34 transmural) myocardial infarction at the time of completion of the intrahospital rehabilitation program that included the regimen of an early activation. A continually-rising type of loading with an initial rating of 150 kgm/min was used. At the instant of effort the ECG was being registered in 4 chest leads. The threshold load-rating was found to average 315 kgm/min and the sum-total of the work performed equaled 2190 kgm. Tests with graded physical loading are of great importance for elaboration of concrete recommendations for rehabilitation and prophylactic measures in patients with acute myocardial infarction.
