title: [Clinical study of purified xuefu capsule in treating angina pectoris].
abstract: OBJECTIVE
  To study the effect of purified Xuefu Capsule (PXFC) in treating angina pectoris (AP).
  
  
  METHODS
  Fifty-seven patients with AP were randomly divided into two groups. Group A (30 cases) was treated with PXFC and western medicine, and group B(27 cases) with western medicine (isosorbide dinitrate, diltiazem or atenolol) alone.
  
  
  RESULTS
  The total effective rates and ECG ST-T changes of AP were 93.3% and 63.3% respectively in group A. These results were all superior to those of group B (P < 0.05). Moreover, in group A the level of plasma endothelin (ET-1) decreased from 85.09 +/- 37.56 ng/L to 61.19 +/- 4.02 ng/L, and that of calcitonin gene related peptide (CGRP) increased from 58.64 +/- 19.30 ng/L to 88.87 +/- 20.41 ng/L. Comparing with group B, these changes were statistically different (P < 0.01).
  
  
  CONCLUSIONS
  The effects of adding PXFC on conventional treatment with western medicine were better than those of western medicine.
