Degree of exercise stress. The exercise intensity level was set using percentage maximum heart rate (% HR) or the exercise factor from the Karvonen formula. For convenience, the approximate systolic blood pressure (SBP) corresponding to each exercise intensity in our institutes is described. The exercise stress with a modified anaerobic threshold (AT) level was much lower than that of other cardiac rehabilitation programs. Exercise with a modified AT level corresponds to an SBP of <150 mm Hg. AAA indicates abdominal aortic aneurysm.
