BACKGROUND Incompleted ST segment resolution (STR) after primary percutaneous coronary intervention (PCI) is associated with worse clinical outcomes. AIM To investigate the association between plasma N-terminal pro B-type natriuretic peptide (NT-proBNP) levels on admission and STR after reperfusion, in a patient with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. ...
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 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...
PURPOSE To investigate the incidence and risk factors of the no-reflow phenomenon in central retinal artery occlusion (CRAO) patients and to determine its effects on visual and anatomic outcomes. METHODS In 102 eyes with CRAO in which arterial recanalization was obtained within 1 week from baseline, fluorescein angiography images obtained at baseline and 1 week were retrospectively reviewed. ...
OBJECTIVES The objective of this study was to investigate the impact of no-reflow phenomenon on 5-year mortality among patients with acute ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI). This impact was also assessed in relation to infarct size. BACKGROUND The impact of no-reflow on long-term mortality in patients with STEMI has ...
Background No-reflow is an important factor as it predicts a poor outcome in patients undergoing primary angioplasty. In comparison with patients attaining TIMI 3 flow, patients with no-reflow have an increased incidence of ventricular arrhythmias, early congestive cardiac failure, cardiac rupture and cardiac death. As such, it is of paramount importance to consider strategies to prevent the oc...
introduction: the precise time of using percutaneous coronary intervention (pci) after fibrinolytic therapy for maximum efficiency and minimum side effects is still undetermined. therefore, the present study was designed to compare the outcome of myocardial infarction (mi) patients who underwent surgical intervention (angiography and pci) within 48 hours of thrombolytic therapy or after that. m...
BACKGROUND The no-reflow phenomenon is an uncommon and critical occurrence which myocardial reperfusion does not restore to its optimal level. Several predisposing factors of the no-reflow phenomenon have been identified. However, at present we know little about clinical predictors of no-reflow after percutaneous coronary intervention (PCI). OBJECTIVES In this study, we evaluated clinical pre...
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 no-reflow phenomenon has been produced in the cerebral hemispheres of the gerbil by 30 minutes of bilateral carotid artery occlusion. The no-reflow phenomenon was found to develop in relation to the fall in blood pressure which occurred on release of bilateral carotid clips. Metaraminol tartrate intravenously prevented the fall of blood pressure and significantly reduced the occurrence of t...
