Myocardial No-Reflow in Humans
Journal of the American College of Cardiology, 2009 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 no-reflow phenomenon has been studied extensively in the basic science laboratory and has entered the clinical arena. No-reflow, which develops largely within the first 2h of reperfusion, is primarily the result of ischemic endothelial cell injury that obstructs the capillary lumen.

Myocardial ‘no-reflow’ — Diagnosis, pathophysiology and treatment
International Journal of Cardiology, 2013 In acute ST-segment elevation myocardial infarction (STEMI), improvement in reperfusion strategies has contributed to improvement in mortality. Nonetheless up to 40-50% of patients who achieve satisfactory epicardial patency do not necessarily achieve ...

On reflow soldering process and reflow profile
2012 13th International Conference on Electronic Packaging Technology & High Density Packaging, 2012In order to obtain good welding quality, some influencing factors of reflow soldering process were studied in this research. A series of welding experiments were conducted in a small reflow soldering oven. Oxidation and surface treatment of soldering materials are important factors in the welding process.

Despite considerable progress in percutaneous coronary interventions, the phenomenon of coronary no-reflow (NR) still represents a serious problem. It occurs when cardiac tissue fails to perfuse normally despite opening of the occluded vessel. The consequences of NR include infarct expansion, early congestive heart failure, ventricular arrhythmias and ...

Assessing the relation between coronary reflow and myocardial reflow
The American Journal of Cardiology, 1998Since the recognition that prompt reperfusion of the infarct-related artery decreases mortality after acute myocardial infarction (MI), we have been interested in optimizing therapeutic regimens to accelerate the establishment of infarct-related artery patency. Although the major endpoint of many angiographic trials has been the acquisition of a patent

No-reflow occurs in up to one third of patients with acute myocardial infarction during acute percutaneous intervention, and occasionally during elective interventions, particularly vein graft intervention. Multiple intracoronary medications will restore flow in most cases.

Solder Reflow Method and Reflow Temperature Profile
Pan Pacific Symposium, 1999ABSTRACT The major cause of integrated circuit package failure mechanisms such as delamination, internal cracking or popcorning is package saturation with moisture and subsequent exposure to high temperature during the solder reflow process.

Management of the no-reflow phenomenon
Pharmacology & Therapeutics, 2011The lack of reperfusion of myocardium after prolonged ischaemia that may occur despite opening of the infarct-related artery is termed "no reflow". No reflow or slow flow occurs in 3-4% of all percutaneous coronary interventions, and is most common after emergency revascularization for acute myocardial infarction.
