In a variable proportion of patients presenting with ST-segment elevation myocardial infarction, ranging from 5% to 50%, primary percutaneous coronary intervention achieves epicardial coronary artery reperfusion but not myocardial reperfusion, a condition known as no-reflow. Of note, no-reflow is associated with a worse prognosis at follow-up. The phenomenon has a multifactorial pathogenesis in...
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...
ne of the corporate goals at AT&T is to eliminate chloroflurocarbons (CFCs) from its manufacturing operations by the end of 1994. Many alternatives have been implemented to meet this objective, including noclean wave soldering using low-solids flux, aqueous cleaning of water-soluble flux, aqueous cleaning with saponifiers and semiaqueous (terpene) cleaning. Part 1 of this article describes the ...
Potential mechanisms of perilipin 2 in angiographic no-reflow = coronary no reflow.
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...
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...
BACKGROUND No-reflow (TIMI < 3) during primary PCI (PCI) for STEMI occurs in 11-41% of cases, indicates poor myocardial tissue perfusion, and is associated with a poor outcome. We aimed to determine predictors and 12 month outcomes of patients who developed no-reflow. METHODS We analysed the PCI database of The Canberra Hospital and identified 781 patients who underwent primary PCI during 200...
