[Exercise-induced attacks of variant angina pectoris].

Ten coronary patients showing no signs of controlled myocardial infarction and responding with transient ST rise to bicycle-ergometric exercise were investigated. ST rise was also recorded from the same leads during a spontaneous attack and cold testing. Coronarography revealed mild coronary arterial lesions. No ST elevation was recorded when bicycle-ergometric test was repeated in the presence of obsidan or corinfar treatment, and the test was negative in most cases.
