No reflow after acute myocardial infarction is an important predictor of infarct size and clinical outcome. However, the exact relationship between no reflow and infarct size remains to be determined, particularly because no reflow may progress during the time course of reperfusion. Control groups of five previous protocols using the anesthetized, open-chest rabbit model of coronary artery occl...

The reaction of brain parenchymal vessels in areas of no-reflow following ischemia in cats was evaluated. A method was devised by which brain biopsies following ischemia were quickly frozen at -170 degrees C, sections were cut and stained and vessel internal and external diameter measured. Vessels in the no-reflow areas had smaller internal and external diameters and thicker walls when compared...

OBJECTIVE The no-reflow phenomenon is associated with a worse prognosis at follow-up for ST-segment elevation myocardial infarction (STEMI) patients with a primary percutaneous coronary intervention. To date, there is no effective method to predict no-reflow. The aim of this study was to establish a predictive system to evaluate the risk of no-reflow by integrating multiple types of information...

AIMS Thromboxane A2 (TXA2) is a key mediator of platelet activation and aggregation, and an important mediator of platelet-induced coronary artery constriction. We sought to investigate whether baseline plasma levels of TXA2 are associated with coronary no-reflow after primary percutaneous coronary intervention (PPCI). METHODS AND RESULTS A total of 47 consecutive patients (age, 62.5 +/- 12.7...

Background: Angiographic no-reflow phenomenon after primary Percutaneous Coronary Intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI) may result in unfavorable outcome. Objectives: The aim of the study was to evaluate the TIMI risk score of STEMI as a predictor of no-reflow phenomenon after primary PCI. Patients and Methods: We analyzed 627 patients presenting w...

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. ...

The no-reflow phenomenon is a complication of percutaneous coronary intervention resulting in poor myocardial perfusion and associated with significant morbidity mortality. It vital for cardiologist to recognise this as it clinically significant. We reported two cases no reflow occurred the same day discussed its predisposing factors, possible aetiology, managements successful outcome.
