Abstract
Purpose: This study is to investigate the influence of acupuncture at acupoints Neiguan (PC 6) and Ximen (PC 4) on the stroke volume and the flow rate of peak value of left ventricle ejection in the patients with coronary heart disease.Methods: 60 cases of coronary heart disease were divided into acupoint Neiguan (PC 6) group and acupoint Ximen (PC 4) group, and the stroke volume and the flow rate of peak value of left ventricle ejection were detected 3 min after manipulating needles and 20 min after retaining needles respectively, then were compared with those before acupuncture.Results: 3 min after manipulating needles, the stroke volume and the flow rate of peak value of left ventricle ejection were enhanced in 46 cases, and 20 min after retaining needles, both the stroke volume and the flow rate of peak value of left ventricle ejection were all enhanced in 34 cases.Conclusion: Puncturing acupoints Neiguan (PC 6) and Ximen (PC 4) could enhance the contractility of left ventricle wall, increase the stroke volume of the heart and improve the myocardial ischemia in the patients with coronary heart disease
