The Effect and Safety of Low-level Laser Therapy in Acute Decompensated Heart Failure Patients.

The advantages of laser acupuncture are a non-invasive, painless, low risk of infection and high safety. Laser acupuncture as a treatment tool has the following advantages1.Painless, 2. Non-invasive treatment, the subject is highly accepted, the risk of infection and needle stick is low, 3. Very few side effects such as fainting, bleeding, 4. The therapeutic dose is easy to operate, and the instrument output frequency, power and time can be controlled. Through the clinical physiological function test plus the verification and analysis of the quantitative test values, it will be more able to define the new role of laser acupuncture treatment in patients with heart failure from the perspective of Chinese medicine.

From the perspective of ancient books, the discussion of heart failure in the etiology and pathogenesis of traditional Chinese medicine was first seen in the "Shu Wen". It is clearly pointed out that "heart qi" is the basic pathogenesis of heart failure. The "qi" and "blood" of Chinese medicine are closely related. The blood line is driven by the gas, the blood is bloody, and the qi deficiency is unable to push the blood to blood. If the qi deficiency, it would lead to blood stasis; There were studies have indicated that traditional acupuncture treatment can increase exercise tolerance and adjust autonomic nerve activity in patients with chronic heart failure, and can reduce their readmission rate and mortality rate in patients with acute heart failure. Studies using laser acupuncture to treat patients with heart failure have also found that they can increase the subject's six-minute walking distance.
