The no-reflow phenomenon in acute myocardial infarction after primary angioplasty: incidence, predictive factors, and long-term outcomes

Abstract

Our results indicate that a fair percentage of patients with TIMI 3 flow after primary angioplasty do not show signs of effective reperfusion (MBG 0) and have a higher in-hospital mortality rate. Myocardial reperfusion after primary angioplasty, as assessed by MBG, strongly correlates with other markers of reperfusion success, including ST-segment resolution.
