Low and medium coronary patients sent to cardiac rehabilitation program at our center within the first 12 weeks after presenting with acute coronary syndrome or been revascularized will be included in the study. The prescription of intensity of effort is based on heart rate reached during the stress test for the initial evaluation in all cases, although at home-program heart rate will be monitored using heart rate monitor and / or by the Borg scale. In this way outpatient group patient could performed training sessions individually and at the time of day that best suits their capabilities. The other program components: control of risk factors, health education and counseling will be identical in both groups of patients.
