[The significance of the performance-lactate quotient in patients following acute myocardial infarct in a preliminary stress test].

According to the risk group classification on the basis of an isoenzyme monitoring n = 67 patients (of them 12 females) with acute myocardial infarction were temporarily differentiated: slight risk (n = 26) on the 14th day, medium risk (n = 16) on the 21st day and high risk (n = 25) greater than or equal to 28. By means of orientating tolerance test and measurement of the lactate concentrations examinations were performed on the day post infarction. All patients with slight risk achieved the physical performance of 375 Watt/min in slight lactate concentrations (less than 4 mmol/l). The performance/lactate quotient (WL-Q) for a slight risk was 1.23 for males and 0.98 for females, for a high risk only 0.66 (males) and 0.53 (females) for a high risk. Patients with high risk were reliably recognized and underwent an individually adapted physical conditioning, taking into consideration the sex-specific differences.

[An orienting stress test following acute myocardial infarct in the elderly].

In a prospective study of 150 patients with definite myocardial infarction (WHO) risk group assignment in the acute phase was done based on lactate dehydrogenase isoenzyme monitoring. 28% of the patients were older than 60 years. The informative functional exercise test was performed by the end of the hospital phase according to three risk groups at different times. Low risk on the 14th day, medium risk on the 21st day, and patients at highest risk on the 28th day after the infarction at the earliest. In connection there this test lactate was determined. In older patients, upper age limit 75 years, any severe complications did not occur during exercise. High-risk patients were objectified by the lactate dynamism, and the decision was made on the further individual outpatient design of physical conditioning by means of low level exercise training.

[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.
