Blood Flow Restricted Resistance Exercises Versus Low Level Laser on Cardiac Functions in Patients With Chronic Heart Failure

This study will be carried out on sixty male and female patients diagnosed with chronic heart failure. They will be recruited from El-Demerdash hospital, Ain Shams university, Cairo. Their ages will be ranged from (40-60) years old. The design of this study will be a randomized controlled trail (RCT).

The patients of this study will randomly assigned into three equal groups (n=20):

Study Group A (20 patients) will receive blood flow restricted resistance exercises in addition to medical treatment program and routine cardiac rehabilitation.

Study Group B (20 patients) will receive low level laser in addition to medical treatment program and routine cardiac rehabilitation.

Control Group C (20 patients) will receive medical treatment program and routine cardiac rehabilitation only.

The program of treatment for the three groups A ,B , and C will be applied once per day, three times per week for 12 consecutive weeks
