This project aims to evaluate, in recent post-AMI patients on dual antiplatelet therapy, the impact of regular exercise training on platelet aggregability, analyzed by VerifyNowP2Y12® test. Secondary exploratory analysis includes: 1) the influence of acute and strenuous exercise on platelet aggregability measured immediately after the two cardiopulmonary exercise testing (CPET) that patients will be submitted; 2) the correlation between the level of platelet aggregability and MSNA in trained and control groups; 3) the influence of exercise training on platelet aggregability measured by Multiplate® adenosine diphosphate (ADP) test and Multiplate® aspirin (ASPI) test; 4) the influence of exercise training on the mean platelet volume (MPV) and platelet count; 5) the influence of exercise training in other laboratorial parameters as lipids, blood glucose and inflammatory activity; 6) finally, the primary endpoint of the study will be evaluated in different prespecified subgroups such as diabetics, elderly, obese and patients with chronic kidney disease.
