Clinical study of thrombolytic therapy by using different drugs and within different time windows in ST segment elevation myocardial infarction

Objective To investigate the clinical effect of ST segment elevation myocardial infarction by using different drugs and within different time windows.Methods We retrospectively analyzed the blood vessel recanalization rates of the 42 patients taking urokinase within six hours after myocardial infarction,the 40 patients taking alteplase within six hours after myocardial infarction,and the 44 patients taking alteplase within 6-12 hours after myocardial infarction.Results The blood vessel recanalization rates of the three groups were respectively 59.5%,80.0% and 29.5%,among which there were statistical differences between each two groups(P0.05).Conclusion The blood vessel recanalization rate is higher by using alteplase in six hours to treat the acute ST segment elevation myocardial infarction,and it is better than using urokinase.There will be more beneficiaries while the earlier of thrombolytic therapy implemented.
