results mean age of patients was 59.47 (sd = 12.48) years, of which 75 (75.8%) were male and 24 (24.2%) were female. based on univariable analysis, white blood cell (wbc) count, pain duration, lv function, maximal st-change, thrombus grade and eccentricity were identified as predictors of the no-reflow phenomenon. after multivariable logistic regression: wbc count and thrombus grade remained th...

introduction: no-reflow phenomenon in coronary vessels, manifested in some patients with reperfused acute myocardial infarction (mi), is associated with poor clinical and functional outcomes. therefore, evaluation of predisposing risk factors can be helpful in risk assessment and identification of patients at higher risk. herein, we aimed to study the predictive factors for the development of n...

OBJECTIVES We sought to elucidate the clinical factors related to the development of no-reflow phenomenon after successful coronary reperfusion in patients with an acute myocardial infarction (AMI). BACKGROUND Myocardial contrast echocardiography revealed that the no-reflow phenomenon is observed in some patients with a reperfused AMI, and those patients usually have poor functional and clini...

BACKGROUND AND OBJECTIVES There is limited information on the transient or persistent no reflow phenomenon in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). SUBJECTS AND METHODS The study analyzed 4329 patients with AMI from a Korean multicenter registry who underwent PCI using coronary stents (2668 ST-elevation and 1661 non-ST-elevation m...

OBJECTIVES The aim of this study was the scintigraphic evaluation of clinical no-reflow phenomenon. BACKGROUND In patients with acute myocardial infarction, the relationship of the severity of reduction of microvascular reflow to the ischemia time or to the secondary extension of myocardial necrosis is poorly understood, and we accordingly conducted a scintigraphic evaluation of clinical no-r...

The phenomenon of no-reflow is defined as inadequate myocardial perfusion through a given segment of the coronary circulation without angiographic evidence of mechanical vessel obstruction. Temporary occlusion of the artery, a prerequisite condition for no-reflow, may be produced in the experimental setting or occur during reperfusion of an infarct-related artery or following percutaneous coron...

BACKGROUND No-reflow is a frequent complication during percutaneous coronary intervention (PCI) for acute ST segment elevation myocardial infarction (STEMI). Available data is limited regarding its impact on short-term outcomes in patients undergoing manual thrombus aspiration. Renal impairment is also associated with higher complication rates in STEMI. Herein, we aimed to evaluate the impact o...

OBJECTIVES We sought to elucidate the long-term prognostic importance of angiographic no-reflow phenomenon after percutaneous transluminal coronary angioplasty (PTCA) for acute myocardial infarction (AMI). BACKGROUND Angiographic no-reflow phenomenon, a reduced coronary antegrade flow (Thrombolysis in Myocardial Infarction [TIMI] flow grade < or =2) without mechanical obstruction after recana...

PURPOSE To review (1) the mechanisms of coronary microvascular reperfusion injury, particularly in the relationships between microvascular endothelium dysfunction, microstructure damage, microemboli and no-reflow phenomena; (2) the no-reflow presentation and management at ischemia-reperfusion to suggest future direction for no-reflow therapy in acute myocardial infarction.
