Clinical Efficiency Observation Of Angina Pectoris With Treatment Of Transcutaneous Electrical Neuromuscular Stimulations Of Diverse Frequency In Neiguan

ObjectiveThe meaning of coronary atherosclerotic heart disease(CAHD) is coronary atherosclerosis leading to vascular stenosis or obstruction, or (and) because of changes in coronary artery (spasm) caused by heart disease, myocardial ischemia or necrosis. Serious harm to human health, coronary heart disease, can cause sudden death at any time, or lead to aneurysm, thrombosis, heart failure. Coronary heart disease also seriously affect the quality of life of patients with recurrent angina patients mental anxiety, limited mobility, brought a lot of obstacles. With the increase in socio-economic level, and change people’s habits, diet and way of working, the upward trend in the incidence of coronary heart disease is worrisome. While Western medicine treatment of coronary heart disease has made considerable progress, both cholesterol management, secondary prevention of coronary heart disease, or a new thrombolytic drugs, rapid intervention and coronary artery bypass surgery techniques, gave coronary heart disease patients to bring the gospel. However, recurrent angina pectoris is still a major problem of modern medicine, and acupuncture treatment for angina pectoris has a unique effect. Which, compared to traditional acupuncture, electrical acupoint stimulation have good reproducibility, operability, etc., become the focus of clinical research. But limited to technical constraints, acupuncture treatment of angina pectoris has not been internationally recognized, and thus require more evidence to support research of higher quality. In this study, Korean therapy device designed by electrical stimulation of different frequencies within the customs points, different clinical efficacy study of angina pectoris, evaluate the clinical efficacy of different frequencies produce different, and evaluation of the safety of electrical stimulation therapy.MethodsIn the Guangdong Provincial Hospital of Traditional Medicine from July 2014 to March 2015,90 inpatients or outpatients with angina pectoris meeting the requirements(the inclusion criterion and also the exclusion criterion in detail) would be included in the study.Subjects were randomly given number (A1, A2...... A30, B1, B2...... B30, C1, C2...... C30)) according to a randomized, single-blind method in which high-frequency treatment group A, group B for the treatment of low-frequency group C was the control group, all patients were given conventional Western medicine treatment group were treated with electrical stimulation of the corresponding frequency on its basis (bilateral customs points, time 30min,1 times a day), to observe and Record efficacy index (according to TCM symptoms of angina pectoris Evaluation Scale, nitroglycerin stopped by rate) and safety indicators (blood, urine, liver function, kidney function),10 days for a course of treatment, a total of two courses. Follow-up two months later, the subjects included in the comparative evaluation of the quality of life before and after treatment (according to the Seattle Angina Scale). The data collected, using SPSS22.0 software, enter the indicator variables of patients, to establish a database. Using the chi-square test, t test methods, the test data to assess differences between the groups and the results obtained.Results(1) In terms of the efficacy of TCM symptoms, according to the efficacy of TCM symptom score sheet, A group was 93.33%, the effective rate was 90.00% in group B, the treatment group total effective rate was 91.67%, the effective rate of group C was 56.67%. Therefore, the treatment group was better than the control group, the difference was statistically significant (P<0.05). Comparison of the treatment groups within each group, there are differences after treatment with that before treatment, the difference was statistically significant (P<0.05).(2) the rate of nitroglycerin stopped by, A group was 66.67%, the effective rate was 66.67% in group B, the treatment group, the total effective rate was 66.67%, the effective rate was 36.67% in group C; therefore, the treatment group was better than the control group, the difference between the two groups was statistically significant (P<0.05), the difference between group A and group B was not statistically significant (P> 0.05).(3) in terms of quality of life, according to survive treatment assessment form, compare the differences of AS、AF、TS before and after treatment, with a statistically significant (P<0.05).(4) in terms of security, comparing before and after treatment of blood, urine, ALT, AST, Cr, show no significant difference (P>0.05).ConclusionWhile conventional secondary coronary heart disease prevention and treatment, the use of. Neiguan percutaneous neuromuscular electrical stimulation, can better improve angina pectoris syndromes, quality of life and reduce the rate of nitroglycerin medication. Transcutaneous electrical neuromuscular stimulation Neiguan within the clinical efficacy of the exact treatment of angina pectoris, and the security is good, but the neuromuscular electrical stimulation at different frequencies of the differences in the present study was not statistically significant.
