After signing the informed consent form, patients will be randomized into 4 groups: 1. Optimized clinical treatment group + physical training for 12 weeks (TF); 2. optimized clinical treatment group (CT); 3. Group with coronary insufficiency without angina (CD); Group 4: normal healthy subjects All patients will be submitted to the following procedures in 2 moments * (times 0 and 3): -Routine laboratory tests including study of total cholesterol, LDL-cholesterol, -HDL-cholesterol, including study of the functionality of HDL-c, triglycerides, complete blood count, renal function, fasting glycemia, glycosylated hemoglobin (HbA1C); - Dosage of biomarkers of myocardial ischemia (ultra-sensitive troponin); - Dosage of inflammatory markers: Tumor necrosis factor (TNFn), interleukins 1 and 6 (IL-1 and IL-6), ultra-sensitive C-reactive protein (CRP); - Vascular endothelial growth factor (VEGF) dosage; - ergospirometric test in cycloergometer; - Echocardiogram with physical stress with evaluation of myocardial perfusion and function; - Evaluation of sympathetic activity through microneurography; - Evaluation of vascular reactivity through ultrasound of the brachial artery. - Evaluation of muscular blood flow through plethysmography; - Isometric exercise protocols; - Mental stress protocol - Quality of Life Questionnaire; - Diary of angina. After the initial examinations, the candidates of the TF group will be evaluated by cardiovascular rehabilitation team, for training prescription, which will be performed in a hospital environment, supervised by a qualified doctor. The rehabilitation may be interrupted in any patient, for safety measure, if the investigator deems it appropriate. All patients in both groups will receive clinical follow-up during the protocol, with monthly consultations during the 12-week protocol period (time 0 to 3), in which clinical evaluations of symptoms and quality of life of the patients will be performed . Any clinical intercurrence will be promptly annotated and evaluated according to the need of the moment. After this period, routine outpatient follow-up is scheduled at the outpatient clinic, and counseling for unsupervised physical training, according to the results of the study. All laboratory, clinical, imaging, and functional parameters will be evaluated before and at the end of the protocol.
