Similarly , no significant differences were observed for infarct size ( @ % LV ; IQR : @ to @ vs. @ % LV ; IQR : @ to @ ; p = @ ) , myocardial salvage index ( @ ; IQR : @ to @ vs. @ ; IQR : @ to @ ; p = @ ) , or angiographic parameters such as blush grade ( p = @ ) and Thrombolysis In Myocardial Infarction flow grade ( p = @ ) .
