To test the value of bicycle ergometry as an exercise test for prognosis in ischaemic heart disease the method was used in 300 men after myocardial infarction. The assessment of prognostic significance of different combinations of indices of the exercise test was made with the aid of the method of consecutive "risk-stratification". Combinations of indices have been determined identifying persons with high death risk from ischaemic heart disease. These patients made up 28% of the total number of persons examined, they comprised 91% of all death cases from ischaemic heart disease and 94% of cases of sudden deaths. Mortality in this group was 25 times higher and the death frequency, 45 times higher than in the other lot examined; a combination of indices has been found for load test with very high risk of sudden death (mortality 71%), and also a combination of indices identifying persons with high risk of repeated non-fatal infarction and of persons with a favourable prognosis.
