OBJECTIVE: To analyze the correlation between local interleukin-6 (IL-6) levels in different parts of blood vessel and the record of Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) after myocardial ischemia-reperfusion (IR) model.

MATERIALS AND METHODS: Establishment of IR model in Yorkshire pigs, the pigs were divided into two groups (n=6). Experiment group pigs were administrated with Shenfu injection (SF) intravenously (1 mL/kg), control group was given saline injection. The blood reflowed after 30 min. TIMI was recorded to evaluate the coronary blood flow and myocardial perfusion. IL-6 levels in venous sheath, coronary sinus, artery sinus, and proximal coronary artery were determined by ELISA.

RESULTS: The records of TIMI in experimental group were higher than that in control group. The difference was statistically significant (p < 0.05). The level of IL-6 increased obviously compared with control group after reperfusion (p < 0.05). Shenfu injection reduced the level of IL-6. IL-6 level at the coronary sinus was positively correlated with TIMI in experimental group (p = 0.03, R2 = 0.97) but not in control group.

CONCLUSIONS: IL-6 levels were significantly increased after reperfusion, which aggravated myocardial injury. IL-6 may be associated with coronary reflow, but further study is needed.
