Effects of Rehabilitation in Patients With Stable Chronic Heart Failure
Heart Failure, Aerobic Exercise, Quality of Life
About this trial
This is an interventional prevention trial for Heart Failure focused on measuring Heart Failure, Aerobic Exercise, Respiratory Muscle Training, Strength Training
Eligibility Criteria
Inclusion Criteria

- Left ejection fraction ≤ 45%.
- NYHA functional class II and III.
- A patient with a diagnosis of CHF for six months including no admission to the hospital or change in medications over the previous 3 months.
- IMW <70% of predicted
Exclusion criteria
- Pulmonary limitation (forced expiratory volume in 1 s and/or vital capacity of less than 60% of predicted value).
- History of significant cardiac arrhythmia.
- History of myocardial infarction or cardiac surgery (6 months).
- Orthopedic or neurologic disease.
- Non echogenic, Unstable.
- Poorly controlled blood pressure.
- End-Stage HF (on the waiting list for transplantation or LVAD).

Combined
Patients follow an alternating aerobic training using a treadmill at an intensity of 60% of maximum heart rate, 3 mn and 3 mn working off an alternative way.To ensure progressive overload appropriate, we adjust moderate intensity aerobic exercise every two weeks with an overall 5% increase in heart rate.
The inspiratory muscle training involves a high intensity endurance training to 60% of PI, max. We recalculate the individual SPImax and PImax in each training session. Patients use the driving tool inspiratory muscle.
The resistance should be measured on 1 RM (Repetition Maximum) for each muscle group. The exercises are performed in three sets of ten repetitions of exercises at 60% of 1RM intensity recalculated every two weeks training.
The control group patients were allocated to a non-training time period, during which they were told to continue their life as before enrollment.
Note that the Aerobic and Inspiratory group participant undergone same protocols of inspiratory and aerobic training stated above, with almost a 5 minutes rest in between.
