Effectiveness of Inspiratory Muscle Training for People With Ischemic Heart Disease Revascularized by Percutaneous Transluminal Coronary Angioplasty.

The control group will perform a standard cardiac rehabilitation program, consisting of 16 multicomponent exercise sessions, health education, and a weekly group of psychological therapy session. The intervention group will do the same program with the addition of Inspiratory Muscle Training (IMT). The following device will be used: Power Breath model: Medic Classic. The training will be performed by adjusting the device load to 70% of the Maximum Inspiratory Pressure value, performing 1 daily training session 4 days a week of 3 sets of 10 repetitions, with a rest of 3 minutes between sets, during 8 weeks. A physical therapist will teach participants how to use the device on the first day and they will be instructed to perform it at home. They will be given a diary to record their compliance. In addition, once a week the physiotherapist will supervise the execution of the IMT by the participants.

The control group will be given the same device as experimental group, but the load for all of the participants of the control group will be 5cm de H2O. This load is so low that it´s not able to induce improvement of the inspiratory musculature.
