Cardiac Rehabilitation, as art and acting science multiprofessional, is based on the training with exercises that provides the post-infarct patients to satisfactorily re-establish the patient's clinical condition and that improve the functional capacity of these individuals.

Evidence shows that aerobic exercise training provides improvements in the endothelial function of this population. However, we do not yet have strong evidence of other modalities of exercise in these parameters in post-infarction patients treated with angioplasty.

Inclusion Criteria:

• Post-acute myocardial infarction patients
• Ergometric test 30 days after the infarction

• Regular use of optimized drugs

Exclusion Criteria:
