[Impacts on neutrophil to lymphocyte ratio in patients of chronic stable angina pectoris treated with acupuncture at Neiguan (PC 6)].
OBJECTIVE
To observe the clinical efficacy on chronic stable angina pectoris treated with acupuncture at Neiguan (PC 6) and explore the impacts of acupuncture on peripheral blood neutrophil to lymphocyte ratio (NLR) in the patients of stable angina pectoris.


METHODS
Thirty patients of chronic stable angina pectoris met the inclusive criteria were randomized into an acupuncture group (15 cases) and a medication group (15 cases), and a healthy control group (15 cases of the same ages) was set up separately. In the acupuncture group, at the same time of the basic medication, acupuncture was applied to bilateral Neiguan (PC 6), once every two days, 3 days a week, totally for 4 weeks. In the medication group, the basic medication was applied, without acupuncture intervention. In the healthy control group, no any intervention was applied. The attack frequency of angina pectoris, dose of nitrogly-cerin, the evaluation of visual analogue scale (VAS), Seattle angina questionnaire (SAQ), the six-minute walking test (6MWT), the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were observed before and after treatment in the subjects. Additionally, the peripheral blood cells were detected to analyze specifically the changes in NLR before and after treatment and observe the relationship between NLR and clinical efficacy.


RESULTS
Compared with the medication group, the attack frequency of angina pectoris was reduced within 30 days (P<0.01); the dose of nitroglycerin was reduced (P<0.01); VAS was reduced (P<0.01) and SAQ was increased (P<0.05) in the acupuncture group. The differences in 6 MWT, SAS and SDS were not significant between the two groups after treatment (all P>0.05). Additionally, compared with the medication group, in 30 days of acupuncture, NLR was reduced apparently in the acupuncture group (P<0.05).


CONCLUSIONS
Acupuncture relieves the clinical symptoms of chronic stable angina pectoris, but has not apparent effects on motor ability and psychological health. Corresponding to that before treatment, the decreased NRL in the patients of acupuncture group suggests the potential good prognosis on coronary heart disease after acupuncture.
