Summary

Cardiac rehabilitation reduces morbidity and mortality after myocardial infarction (MI) and improve the sympathovagal balance. The autonomic nervous system (ANS) can be explored by the variation of heart rate (HRV). The HRV is a fatigue marker and guides the athletes training programs. A smartphone app can measure the HRV via a heart rate monitor.

The main study objective is to compare the effect on the functional capacities of a re-training adapted to the HRV compared to a standard program in the post-MI The secondary objective is to compare the patients' quality of life according to the rehabilitation program and to validate the HRV smartphone app.

This is a prospective, multicenter study. Post-MI patients treated with angioplasty with a LVEF\> 40% are randomized into 2 groups: HRV (re-training adapted to HRV daily: 10W decrease or increase in workload according to the HRV) or control (continuous training in SV1). Patients underwent a cardiopulmonary test, a walking test (TM6) and a SF36 questionaries' at the entrance and exit. The taking of HRV was done every morning in a standardized way via the smartphone app during the 20 re-training sessions.

HRV measurement

Patients in group A (control) will benefit from a standard re-training protocol based on initial functional abilities. The training is done at a target heart rate corresponding to the heart rate reached at the first ventilatory threshold (about 55% of VO2max). * Patients in group B (study strategy) will benefit from a re-training protocol based on HRV and initial functional abilities. Any increase in HRV compared to the previous day will result in an increase in workload of 10Watt. Any increase or decrease in HRV for 3 days in a row will cause the stagnation of the workload for 2 days. HRV is measured every day in each group via a heart rate belt and a smartphone App.
