[Early exercise testing after myocardial infarction (author's transl)].

203 patients suffering from acute myocardial infarction performed a cycloergometric submaximal exercise test before leaving hospital. The causes for stopping the test were fatigue or submaximal heart rate (24,1%), angina (14,2%), ischaemic S-T changes (28,08%), arrhythmias (4,9%) and changes of blood pressure (17,2%). No important complications were observed. The test proved useful for the definition of more objective criteria in order to prescribe an individualized rehabilitation programme. Above all it was possible to prescribe treatment which would not have otherwise been prescribed at the time of discharge. The short term prognostic value is not, however quite clear as yet.
