| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control group | No Intervention | Patients randomised to control group will get usual recommendations regarding physical activity after a discharge from inpatient cardiac rehabilitation. | |
| Intervention group | Experimental | Patients randomised to intervention group will continue home exercise training that will last 12 weeks and consists of endurance, flexibility, balance and cardiovascular resistance training performed with low to moderate intensity, in 20-60 minutes sessions, five times a week. Study participants will be asked to wear wrist and chest unobtrusive devices during active day time or at least during the training session and two hours before and after. Study participants well receive telephone calls every other week and were asked to answer questions regarding their health and physical activity. |

| Home training program | Other | Subjects randomized to the IG will participate at home training program that will last 12 weeks and consists of endurance, flexibility, balance and cardiovascular resistance training performed with low to moderate intensity, in 20-60 minutes sessions, five times a week. Study participants will be asked to wear wrist and chest unobtrusive devices during active day time or at least during the training session and two hours before and after. |
| Measure | Description | Time Frame |
|---|---|---|
| Autonomic nervous function by Heart Rate Recovery (HRR) | HRR (beats per minute) is a difference of the maximal HR obtained during stress testing and HR during the recovery period: HR30-360 the decay of heart rate from 30 to 360 s after the recovery onset. | 3 weeks |
| Autonomic nervous function by Heart Rate Recovery (HRR) | HRR (beats per minute) is a difference of the maximal HR obtained during stress testing and HR during the recovery period: HR30-360 the decay of heart rate from 30 to 360 s after the recovery onset. | 12 weeks |
| Autonomic nervous function by Heart Rate Fragmentation (HRR) | HRF measured by RR interval indexes:percentage of inflection points (PIP), inverse of the average length of the acceleration/deceleration segments (IALS), percentage of short segments (PAS), percentage of alternation segments (PSS). | 3 weeks |
