title: [Observation on therapeutic effects of electroacupuncture at Neiguan (PC 6) on silent myocardial ischemia].
abstract: OBJECTIVE
  To observe the therapeutic effects of acupuncture at Neiguan (PC 6) on silent myocardial ischemia (SMI).
  
  
  METHODS
  Forty patients with SMI were randomly divided into an electroacupuncture group and a medicine group, 20 cases in each group. The Electroacupuncture group was treated with electroacupuncture and Neiguan (PC 6) was selected as the main acupoint, and the other acupoints were selected by syndrome differentiation. The medicine group was treated with oral administration of compound Danshen dripping pill. The total effective rate, heart rate, blood pressure and dynamic electrocardiogram in 24 h were compared.
  
  
  RESULTS
  The total effective rate of 95.0% (19/20) in the electroacupuncture group was better than that of 75.0% (15/20) in the medicine group (P < 0.05). After treatment, the heart rate, systolic blood pressure and diastolic blood pressure in the two groups were decreased significantly (P < 0.01, P < 0.05) and the electroacupuncture group was superior to the medicine group (all P < 0.05). The SMI duration and the number of ST segment depression were decreased significantly in both groups after treatment (P < 0.01, P < 0.05) and the electroacupuncture group was superior to the medicine group (P < 0.05).
  
  
  CONCLUSIONS
  Acupuncture at Neiguan (PC 6) has a good therapeutic effect on SMI. It can decrease the heart rate and blood pressure, reduce the afterload in left ventricular and is superior to that of compound Danshen dripping pill.
