heart failure are not directly related to effort, and in
such cases medical supervision could lead to earlier
diagnosis. Furthermore, it is more advantageous to
close a stent during exercise stress testing or during a
medically supervised training session than to do so at
home.
The selected population did not represent all patients in rehabilitation, because some patients initially admitted to the center may have presented a contraindication to physical training and would thus have been
excluded from our registry. The registry included only
exercise-related complications, and the rate of events that
may have occurred during the same period but outside
the time of exercise is not known. Therefore, further studies involving other analytical problems (eg, potential predictors of adverse cardiac events or postsurgical complications) may be warranted.
In summary, the risk of cardiac events during exercise testing and training appears to be very low at present,
but such events seem difficult to predict. Our results concern supervised exercise training, but they should induce cardiac patients to be more active and to practice
physical activity on a regular basis.28
