Collateral blood flow can predict myocardial blush grade in primary coronary intervention

Abstract

OBJECTIVES: Our aim was to investigate whether collateral flow may predict myocardial blush grade (MBG) in acute myocardial infarction patients undergoing primary percutaneous coronary intervention. BACKGROUND: No-reflow is a well known phenomenon associated with increased morbidity and mortality due to underperfused myocardium; therefore early prediction of no-reflow is of major importance. We have observed that in patients with good …
