Has low-dose intracoronary thrombolysis gained ground in primary percutaneous intervention?

Reducing thrombus burden would improve patient's outcomes. Low-dose intracoronary thrombolytic agent administration has been considered to improve myocardial microcirculation, cardiac function, and major adverse cardiovascular events in patients presenting with ST-segment elevation myocardial infarction and high thrombus burden. This paper discusses published meta-analyses on intracoronary thrombolysis in primary percutaneous intervention.
