    Abstract:
    The aggregability of the blood platelets and their ultrastructure were examined during the bicycle exercise test in 20 patients with ischemic heart disease and stable angina pectoris. In 8 patients with unequivocally positive exercise test a significant increment of stimulated aggregation from 58.2 (CV7%) to 71.2 (13.6%) resulted in comparison with a group of patients who did not fulfilled criteria of exercise testing. In this group the aggregability dropped from 56.0 (5%) to 38.7 (8.4%) eventually. No changes in a diameter and shape were observed during the exercise test was positive the amount of granules decreased. It is considered to be an indirect proof of the functional changes in thrombocytes during a certain rise in aggregability.
