title: [Effect of danshen chuanxiongqin injection on the myocardial damage of unstable angina patients undergoing percutaneous coronary intervention].
abstract: OBJECTIVE
  To observe the effect of Danshen Chuanxiongqin Injection (DCI) on the myocardial damage of unstable angina (UA) patients undergoing percutaneous coronary intervention (PCI).
  
  
  METHODS
  76 UA patients were randomly assigned to the test group (39 cases) and the control group (37 cases). Routine treatment of Western medicine and PCI were given to all patients. But 10 mL DCI was intravenously dripped to patients in the test group by adding in 250 mL normal saline three to five days before PCI, once daily, lasting for 7 to 10 days. Changes of platelet P-selectin positive expressions before and after medication, the thrombolysis in myocardial infarction (TIMI), myocardial perfusion (TMP) score, levels of creatine kinase-myocardial band (CK-MB) and troponin I (TnI) after PCI were observed in the two groups.
  
  
  RESULTS
  After medication the P-selectin positive expressions was lower in the test group than in the control group (2.45% +/- 1.42% vs 4.43% +/- 1.79%, P<0.05). After PCI the incidence of TMP 0/1, the levels of CK-MB and TnI were lower in the test group than in the control group at the same phase, showing statistical difference (P<0.05). No cardiac event occurred in the two groups during the hospital stay.
  
  
  CONCLUSIONS
  Administration of DCI before PCI could effectively inhibit the activation of platelets, improve post-operative myocardial blood perfusion, and lower the incidence of the myocardial damage.
