Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Clinical treatment physical training
Patients with optimized clinical treatment group that will do physical training for 12 weeks. They will do the tests in moment 1 and after 3 mounths. The intervention is the Cardiac Rehabilitation. |
The physical training program will start shortly after the initial exams have been completed. The physical training protocol will consist of a 12-week duration, with a frequency of 3 weekly sessions of 60 minutes duration each. The intensity will be prescribed from the echocardiogram with effort and cardiopulmonary test. All sessions will be monitored by telemetry and will be distributed as follows:
|
No Intervention: Optimized clinical treatment
Patients with optimized clinical treatment group that will not do physical training.They will do the tests in moment 1 and after 3 mounths.
|
|
No Intervention: Coronary insufficiency without angina
Group with coronary insufficiency without angina and will not do physical training.
They will do the tests only one moment.
|
|
No Intervention: Normal healthy subjects
Group normal healthy subjects, without coronary injuries, diabetes, hypertension and another chronic disease.
These group have be sedentary and will not do physical training.
They will do the tests only one moment.
