[Submaximal stress test and lactate dynamics following acute myocardial infarct in elderly patients].

Eighty patients were physically conditioned after definite myocardial infarction (WHO definition). The percentage of patients older than 60 years was 28%. Physical conditioning as part of the non-drug therapy of acute myocardial infarction is of great importance also to older patients. The older patient impaired in his/her performance becomes physically more capable by an individually adapted conditioning and can socially better be re-integrated. A suitable parameter for the demonstration of the efficiency of physical conditioning in older patients is the lactate dynamics.
