Effectiveness of a Cardiac Rehabilitation Program in Elderly Patients With Heart Failure.

"Strength exercises: strengthe exercise will be performed twice a week for 12 weeks, 4-6 series at 60% RM at the beginning of the program, with a progression towards 85% RM in each functional movement at the end of the intervention. The patients will rest for 90 seconds between series and 3 minutes between exercises. Each session has an estimated duration of between 45-60 min.~Aerobic exercise: aerobic exercise it will be performed twice a week for twelve weeks, between 45-60 min each session of aerobic exercise. It will be developed on a treadmill or cycle ergometer at 50% of HR max at the beginning of the program with a progression towards 80% of HR max at the end, continuously or internally. The Borg scale will prevail over the objective data to adjust the intensity of each patient, Borg = 10/20 or mBorg = 5/10 at the beginning, with progression to Borg = 14/20 or mBorg = 8/10 at the end."

The control group will receive two education sessions per week for twelve weeks on the complications derived from Heart Failure (HF), functional deterioration, and healthy lifestyle habits.
