title: [Comparison of effects of taizhi' an capsule and pravastatin on vascular endothelial function in senile patients with coronary heart disease].
abstract: OBJECTIVE
  To explore the anti-atherosclerosis effect of Taizhi'an Capsule (TZA) for providing a theoretical base of its application in preventing coronary heart disease (CHD), by way of observing the effects of TZA and pravastatin (PVT) on vascular endothelial function in senile patients with CHD.
  
  
  METHODS
  Seventy-eight Senile patients with CHD were randomly divided into the TZA group and the PVT group, 39 in each group. Changes of carotid arterial intima-media thickness (IMT) and brachial arterial endothelium dependent diastolic function (FMD) before and after treatment were observed by non-invasive ultrasound test technique, and levels of serum nitric oxide (NO) and plasma endothelin-1 (ET-1) were determined as well.
  
  
  RESULTS
  After TAZ treatment, IMT decreased from 1.21 +/- 0.17 mm to 0.91 +/- 0.13 mm, FMD increased from 5.02 +/- 0.58% to 8.97 +/- 0.39%, ET-1 lowered from 95.93 +/- 19.41 ng/L to 49.35 +/- 53.27 ng/L, and NO enhanced from 42.56 +/- 14.12 mumol/L to 69.84 +/- 21.96 mumol/L; after PVT treatment, the corresponding changes were 1.25 +/- 0.21 mm to 0.88 +/- 0.32 mm, 4.90 +/- 0.37% to 8.12 +/- 0.25%, 89.35 +/- 10.02 ng/L to 47.96 +/- 11.05 ng/L and 51.71 +/- 9.39 mumol/L to 72.93 +/- 16.51 mumol/L, all the changes were statistically significant.
  
  
  CONCLUSIONS
  TZA can obviously improve the vascular endothelial function in old patients with CHD, which has the anti-atherosclerosis effect similar to that of PVT.
