[RESULTS] In treatment group , the percentage of thrombolysis in myocardial infarction-3 ( TIMI-3 ) flow in the infarct-related artery ( IRA ) increased ( 89.3 % to 85.4 , p < 0.05 ) , blood flow in the IRA calculated with TIMI frame count method enhanced [ ( 1.68 0.23 ) ml/s to ( 1.42 0.31 ) ml/s , p < 0.05 ] , STR on electrocardiogram ( ECG ) enlarged [ ( 64.3 7.84 ) % to ( 48.6 6.47 ) % , p < 0.05 ) ] and the prevalence of MACE decreased ( 10.7 % to 18.8 % , p < 0.05 ) , all of which were significantly different from those of control group , but no statistical difference in complications was observed between two groups ( p > 0.05 ) .
