Relation of myocardial blush grade to microvascular perfusion and myocardial infarct size after primary or rescue percutaneous coronary intervention.


Angiographic myocardial blush grade (MBG) is a potent predictor of long-term outcome after percutaneous treatment of myocardial infarction, yet little is known regarding the underlying pathophysiologic features. The relation between MBG and cardiovascular magnetic resonance (CMR)-defined amounts of necrosis and microvascular obstruction was examined in 27… (More)
