To assess the difference between cardiovascular responses to treadmill exercise (TM) and those to bicycle ergometer exercise (EM) in provoking @entity3361 , we compared the ST segment shifts (elevation or @entity308 ) during TM and EM in 67 @entity1 with @entity951 . @entity3361 was demonstrated on angiography. Both TM and EM were performed on the same day during a medication-free period. For both tests, multistage, symptom-limited exercise protocols were used; EM in the morning and TM in the afternoon. The results obtained were as follows: 1. Rate-pressure products at peak exercise during TM and EM were similar. Systolic blood pressure levels at peak exercise were higher during EM than during TM (p < 0.01). The @entity1 ' heart rates at peak exercise were higher during TM than during EM (p < 0.01). Diastolic blood pressure levels at peak exercise were higher during EM than during TM (p < 0.05). 2. Exercise-induced ST elevation occurred more frequently with TM than with EM (19% vs 9%, p < 0.05). 3. Exercise-induced ST @entity308 was provided in 27 @entity1 during TM and in 13 during EM (40% vs 19%, p < 0.01). Among 45 @entity1 without significant lesions, ST @entity308 occurred in 19 during TM, but in only 7 during EM (42% vs 16%, p < 0.01). In conclusion, @entity3361 seemed to occur more frequently with TM than with EM. The mechanism causing such difference remains to be elucidated, however, we speculate that the difference between TM and EM as to enhanced @entity3002 and coronary perfusion exercise may be related to the difference in the incidence of @entity3361 .
