RESUMO
OBJECTIVE: To observe the reperfusion rate of acute myocardial infarction (AMI) affected by inspiring nitric oxide (NO) and resolving thrombus through veins. METHODS: Sixty cases with AMI were randomly divided into test group (n=30) and control groups (n=30). Patients in test group were cured with NO (20+/-1)mg/L inspiration for 30 minutes at once before admission and urokinase (150x10(4) U) adding 0.9% sodium chloride intravenously injected within 30 minutes, while patients in control were treated with urokinase as the same method of the test group. RESULTS: The reperfusion and non-reperfusion patients were 25 and 5 cases in test group, and they were 19 and 11 cases in control group. The reperfusion rate of AMI in test group was significantly higher than that in control group 83.3% vs. 63.3% (P<0.05). No peak periods of lactate dehydrogenase (LDH) and creatine phosphokinase (CPK) appeared in test group, and the difference was significant compared to the control group (P<0.05). CONCLUSION: NO inspiration before urokinase is an effective method to treat AMI and advance the reperfusion rate.
