[Importance of left ventricular function for active early ambulation following acute myocardial infarct].

On the 4th postmyocardial infarction day a risk group determination among n = 80 patients was undergone on the base of LDH-isoenzyme-monitoring. The active early mobilization was carried out following corresponding risk groups: less risk (38%) until the 14th, middle risk (23%) until the 21st and high risk (38%) until the 28th postmyocardial infarction day or longer. The average period of hospitalization was 21.1 day. The exercise load test was done successful in 97% by patients with low risk and in 40% by patients with high risk. The ejection fraction was 51.3% for patients with low risk and 38.5% (p less than 0.01) for patients with high risk. The exercise test at discharge is usefull for check of the risk from the acute phase and for the determination of high-risk patients for physical conditioning.
