Summary

This study is designed to compare between blood flow restricted resistance exercises and low level laser on cardiac functions in patients with chronic heart failure

Conditions

  • Heart Failure NYHA Class II

Interventions

DEVICE

Acupuncture LLLT:

Acupuncture LLLT: This mode of therapy will be conducted for study group B as follows: A therapeutic unit (M6 MLS from ASA laser, Italy) with wavelength 905 nm, output 5-20 MW, laser beam spot size 0.785 cm2, energy density 91 J/cm2, energy delivered 28 J, and frequency 500HZ. Laser probe will be placed in intercostal space both anteriorly and posteriorly on chest wall. Each acupuncture point will be stimulated with a laser for 60 s, three weekly sessions over 12 successive weeks. Anterior chest wall acupuncture points are {LU1, LU2, CV17, (Ren17)}, posterior chest wall from a prone or setting position of the patient {UB13, (BL13), UB 17(BL17)}.

OTHER

Blood flow restricted resistance exercise:

The subject will warm up and cool down for at least five to seven minutes each, (before and after exercise). The patients will perform blood flow restricted resistance exercise (BFRRE) at 40-80% of 1RM with 50% limb occlusion pressure (LOP), while placing cuff on midthigh and perform four sets of bilateral knee extension exercise, each set consist of 15 repetitions with 30-60 second rest in between sets and relieve cuff pressure in rest period, three weekly sessions over 12 successive weeks

DRUG

Medical treatment

All patients will enroll to maximum doses guideline medical treatment that include (Beta blockers-Aspocid- Ator-Concor-Tritace). Also all patients will adhere to routine cardiac rehabilitation: The patients will enroll in CR program for 12 weeks, three times per week for 12 week. Moderate-intensity treadmill exercise training achieving a target heart rate of 40-60% of HR reserve (calculated from pre-exercise symptom-limited treadmill exercise stress test by modified Bruce protocol). The duration of each session was 30- 45 minutes (5-10 minutes of treadmill warm up, followed by 20-30 minutes of aerobic continuous treadmill training and terminated by 5-10 minutes of cooling down
